19141 Bowditch-Notes on Aulacophora Olivier 133 Leptogaster loewi sp. nov.
Similar to L. fazrillaceus and L. jIavipe8. Legs pale; hind femora with traces of a dark band over swollen part, tip of hind tibize dark. Antenn~ yellow; thorax grayish brown above, with traces of median stripes, the two bristles each side black; abdomen grayish brown, tips of third, fourth, and sfth segments yellowish; vena- tion yellowish-brown, as in L. jlavipes. Differs from L-jlavipes (andfau2laceus) in lacking pale on abdomen before middle of segments, and the more distinct band on hind femora. Length, 10-12 mm. From Paeonian Springs, J7a., 28 June, and Ithaca, N. Y., 7 July. NOTES ON AULACOPHORA OLIVIER AND OIDES
WEBER.
BY F. C. BOWDITCH,
Brookline, Massachusetts.
In the arrangement of my Austral-Malayan species of Aula- cophora the following notes occur which may aid in the study of this group.
In Mr. Baly's table of males, Linn. Soc. Journ. vol. xx, p. 2, No. 14 postica Chap. is placed in 5 A-B: it should be in 5 A* hav- -
ing the middle anal segment sulcate longitudinally, as stated by him in the description, p. 12, and verified by examination. Unicolor Jac. cited by Baly 1. c., p. 23, states that the 3 is un- known; the description by Mr. Jacoby, Notes Leyden Mus, vol, v, p. 201, speaks of five specimens, all Q 's; one of these five exam- ples in the first Jacoby collection is now before me and is a 8 : the middle lobe of the anal segment is slightly concave, placing it in 5 AdB of Baly's table of d's. Mr. Baly speaks of its resemblance to Boisduvali but the anal sulcation seems to me to differ some- what and needs further comparison. If the two are identical it seems that intermediate forms must occur and I have seen none. Semilimbata Baly described 1. c., p. 74, has no characters given for the 3 ; the type specimen apparently came from ccNew Guinea, (Wallace)"; in the first Jacoby collection among the unnamed material is a 3 with the same label; the middle anal segment is deeply concave placing the species in Baly's A*. Denticornis Blackb. seems to me to be the same as jraudulenta Jac. The peculiarities of the two first joints of the 3 antenne described by Mr. Blackburn seem to me to be present in the 8 type of jraudulenta (in my collection) and to have been overlooked

by Jacoby in his description; unless the specimen is held at a cer- tain angle the points spoken of are easily overlooked. Frontalis, Baly, 1. c., p. 182, describes the third joint of the an- tennz "twice as broad as long.'' Comparison with a specimen in my collection labeled "type ex Baly" seems to show the words to be accidentally transposed so they should read "twice as long as broad."
Borrei Baly (pectoralis Jac) is described as having the thorax impunctate (Ann. Mus. Gen. 1886, p. 50) ; the types now in my collection all have the surface near the anterior angles punctured9 so the description should read, "impunctate except the anterior angles." Mr. Blackburn in describing his A. Richmondensis Proc. 2001. SOC. N. S. W. 1701. v, 1890, p. 360, relies upon Mr. Jacoby's description to separate the two forms, which seem identical; in Mr. Jacoby's second collection he has under the name pectoralis specimens from N. S. W. (square purple label) which exactly agree with the description of Mr. Blackburn's species. A. celebensis Jac. 1. c., p. 52, typically has basal and ante-apical spots, what seems an extreme variety, has the elytra entirely black, except for a small flavous spot at the apex, or a slight margin in the middle of the side, the latter very like (flavo-marginata Duv.). All come from Toli-Toli, No. Celebes (Fruhstorfer). Aulacophora blackburni sp. nov.
Reddish, castaneousy labrumå face and antenn~ flavous, mandiblesy eyesy tibie and tarsi bIackishy femora fuscous at apex, the joints 3y 4, 5 of the antennze dilated in the male like denticornis Jac.
Type: 1 3 Manila (coll. Bowditch). Lengthy 5 mm. Head impunctate with two almost circular, deep fov~, one on either side of the vertex ibove the eye, antennz a little more than half the length of the body, first joint clavate, second joint very small, roundedy with a minute point externally in the middle, third joint in the shape of a long pointed perpendicular tooth, the fol- lowing two joints broadly dilated acutely pointed at their anterior anglesy the fol- lowing joints elongate nearly equal, thorax twice as broad as long, finely punctured, very sparsely and finely on the disky sulcation nearly straight, abbreviated on either sidey elytra strongly depressed below the base, showing very lightly punctulate, last abdominal segment longitudinally lightly concave or sulcate. The above specimen was in the second Jacoby collection mixed with examples of sirnilis Oh. Denticornis Jac. is the only other species known to me with the peculiar dentate antenna1 third joint, and this form should be placed next it.

19141 Bowditch-Notes on Aulmophora Olivier 135 In Nov. Zoolog. vol. i, pp. 299-300, Mr. Jacoby described Oides unifasciata and sutu~alis, calling attention to the produced metasternum, imitating to some extent the genus Doryphora, four nearly allied additional forms have occurred and are here made known. Mr. Jacoby further intimates a new genus for his forms, but I have allowed all to remain in Oides for the present: the two Jacoby species and also the new ones are rather more chunky and- robust than the other species of Oides and may be almost picked out by the shape alone.
Oides confusus sp. nov.
Convex ovate? shining; head? antenne and below? mostly black? thorax flavous, elytra reddish fulvous~ with a common broad basal black band? not attaining the lateral edge and a large round subapical spot on each elytron black. 9 with metasternum produced into a well marked obtuse process? last ventral segment obtuse? impressed on either side. Type 9 Milne Bayy Br. N. Guinea (coll. Bowditch). Length? 12 mm. Imitates 0. mbra Blanch. in size and colory but more convex and widery antenn~ attaining the rear edge of basal black band with the two or three basal joints more or less fulvou~~ third and fourth equal and longer than the othersy head with a few fine punctures and an impressed line on the front? thorax very finely punctulate over its entire surface and all the angles rounded? scutellum smoothy truncate be- hindy elytra finely punctulate over the entire surface? abdomen edged with rufous spots? the cox= and base of the femora are also more or less tinged with rufous, probably mixed with rubra in many collections. Oides binotata sp. nov.
Convexj elongate? shining rufousy mouth? eyes? thorax and a large median lateral spot on each elytron black.
3 and Q with metasternum produced into a well- marked obtuse process.
Type: 3 Q Kapour Holl, N. Guinea (Friihstorfer) coll. Bowditch. Length, 11 mm.
Head with a few faint punctures on the front, which is smooth and shining with a faint median line, antenne reaching the middle of the elytra? thorax shining? faintly impressed on either side? rather strongly, evenly puncturedy sides strongly margined, the angles obtusey the anterior ones slightly reflexed? scutellum with apex obtusely rounded? elytra smooth, shining? oblong, rather strongly and evenly punctate? the sutural margin somewhat thickened posteriorlyy the black spot on each elytron is transversely rounded and a trifle nearer the lateral edge than the suture; the meta- sternum process, with the color easily separate this form. Oides gahani sp. nov.
Ovate flavous? eyes? antennte except basey elytra except anterior third, black, the flavous part of the elytra being narrowest at the scutel and from there curved back to meet the lateral margin at about the middle? 8 and 9 with metasternum produced into a well marked obtuse process.
