SPATHULATE HEAD SETAE ON THE LARVA OF CHAMYRIS CERINTHA TREITS.
BY HARRISON G. DYAR, WASHINGTON, D. C.
I had occasion to notice spathnlate head setae in the case of Cfcisaus melsheaheri (Journ. N. Y. ent. soc., iv, 9%). A second instance is found in Chamyria ce~int/ia, though here it is the first epicraneal seta that has become flattened instead of the fourth, and the structure disappears at the last moult. A condensed description of the last stage of the larva has been given by Mr. Coquillett (Papilio i, i;6); but he does not refer to the ~pathulate hairs of the early stages. I assume the number of stages for convenience in indicating them; I do not know that seven is the true number.
Stage IV-
Slender, anal feet divergent;
head strongly bilobed, the lobes angular, the apex black with a line passing down both front and back lateral angles ; green ; seta 1 short, spathulate; width 1.2 mm. Body with joint 12 slightly enlarged; setae single, stiff, coarse, black; i, ii, iii, v, pointing sharply forward, iv and vi backward, all normal, seta iv behind the middle of the spiracle; leg shields small with few setea. Green; tu- bercle i on joints 5 to 7 enlarged and black ; an obscure white lateral line above wart iii ; anal feet and a subventral dash on joint 12, crimson. The two anterior pair of abdom- inal feet are slightly weaker than the others. Stage V 'The same; a broken reddish
line runs along warts 1 and ii, which are nearly in line; white lateral line distinct. S-e VI. The same; the white lateral
line is sharply edged; head green, the black lines fainter than before, seta i still spath- date.
Stqe VII. Head more rounded, seta i no
longer spathulate, very short; the lobes are low, not angular. Body slender, dorsum between the distinct white lateral lines filled in with dark vinous purplish, the subventral regions green. Setae coarse, long and black ; tubercle ii on joint 12, and i on 13 large, high and conical, the others normal.
The line on the head is abbreviated,
partly or wholly brown ; width 2.5 mm. Ab- dominal feet essentially equal.
Foodplants. Wild cherry and plum.
Larvae solitary, very active and quickly spring off of the plaht when disturbed, like some Deltoids.
AN APPARENTLY NEW LECANIUM FOUND ON WHITE CEDAR. BY T. D. A. COCKERELL AND G. B. KING,
This article is written by Mr. Cockerell, but a form of Ljtetche~f, especially sitice he but is partly based on Mr. King's notes and had found some ~e~itablefletcheri in Massa- observations. chusetts on arbor-vitae. A close examina- When Mr. King sent me a small almost tion of the Cedar scale, however, reveals globose Lecanium found on White Cedar, differences which must surely be specific, so I could hardly believe it could be anything the insect is described herewith.

TWO W\V COCCIDS FROM
BERMUDA
IN January of this year, the writer in his search for coccids infesting green-house plants, observed a potted plani in one of the conservatories visited, trimmed quite close to its roots, and the remaining stumps ^ell covered with a small clear white scale. The plant in question \\as recognized at once to he Cycas ~caoiuia. Upon enquiry it. was
learned that this plant was imported from Bermuda last year. Some of the old stems with the coccids were taken for study. One of the species proved lo be A.s$idiotus he&- me Vallot, a very common species throng11 the United States, and the other coccid was new to the writer, who sent a mount and
some of the scales to Prof. Cockerel1 for determination. He identifies it as Aulacm- å´pi eleyafts Leon. Described as ZZowa?dia eleyans, and only known hitherto from
Portici Italy, on Cycm revolt&, The $
and (^ scale are unknown. The species
differs from typical Aulaca&pis by lucking the circ~imgenital glands. The occurrence of this species is of much interest find the mc.cids of Bermuda are almost unknown.
There are only two other species known to the writer recorded from those islai~cls, Mytilmfi citricola Pack. on orange and
lime trees, and Chiona~pts citri Conlst. 011 orange. Geo. &King.
