CAMBRIDGE ENTOMOLOGICAL CLUB.
(Continued from 9. 70.)

club was held at 61 Sacramento St., Cam- bridge, 12 Nov., 1886. In the absence of the president, Mr. S: H. Scudder was chosen
chairman. The secretary announced the
withdrawal from the club of Mr. Thaddeus Willian~ Harris. As Mr. Harris was a mem- ber of the executive committee a ballot was taken and Dr. George Dimmock elected to
fill the vacancy.
Dr. G: Dimmock read a letter from Mrs.
M. L. Owen, of Springfield, with reference to a curious case, exhibited a few meetings ago, which rebembled that of one of the trap-door spiders.
He then showed specimens of what ap-
peared to be a wingless species of chalcidae from Cambridge, and also a specimen of
Gra-pfa interrogufioni~. with its chrysalis, which emerged 10 Nov.
Mr. S : H. Scudder showed a photograph of Dr. Asn Fitch taken from an ambrotype.
Mr. Scudder then read a letter from Miss Adele M. Fielde, in which she described
some of her observationb on insects in China. He then exhibited drawings of Pujiliophi- lenor and P. chalcas, by Mr. J. H. Emerton. 10 DEC., 1886.-The 124th meeting was
held at 61 Sacramento St., Cambridge. In the absence of the president, Mr. S: H. Scud- der was chosen chairman.

Nomination no. 143, that of Mr. Paul
Howard Cheney of Cambridge, for active
membership was presented by Messrs. Child and Dimmock.
Dr. G : Dimmock read a paper on the " Re- production of lost limbs in Coleoptera," in which he gave a somewhat detailed account of experiments which he had tried of ampu- tating the legs of larvae of coccinellidae and the subsequent reproduction of these limbs. The paper was prefaced by an account of
what had been recorded by previous observers upon the reproduction of lost limbs in in- sects, and will be published in full in Psyche. Mr. S : H. Scudder remarked upon an arti- cle by Graber in which that author arrives at the conclusion that the antennaeare the only organs sensitive to smell.
He then read extracts from Plateau's "Une experience sur la fonction des antennes chez la blatte" in which he concludes that the palpi as well as the antennae are capable of the perception of odors.
Mr. Scudder then showed "The butterflies of India," by G. F. L. Marshall and de Nice- ville, and briefly reviewed the work.

November-December 18S8.1 PLY 2TffE. 139
Mr. S: H. Scudder then showed some
plates from a work which he has in prepara- tion upon our New England butterflies.
11 FEB. 1887.-The 126th meeting was
held at 61 Sacramento St, Cambridge, 11
Feb., 1887. The meeting was called to order at 8 P. M., the president, Mr. J. H. Emerton in the chair. Nine members were present. The secretary, in behalf of the executive committee, stated that a contract had been drawn up between the club, as party of the first part, and Mr. B : Pickman Mann, as party of the second part. Under this con- tract, Mr. Mann was to assume the publica- tion of Psyche. The contract was then read, accepted, and the secretary authorized to act as assistant treasurer as per contract. The secretary was empowered to levy an
extra assessment of fifty cents on all resi- dent members.
Mr. S : H. Scudder read a paper on the
injuries to plants by white ants. Maple
trees have been quite seriously injured by Temesflavz'pes. Mr. Scudder found many
of the geranium cuttings in a greenhouse attached to Mt. Auburn cemetery injured by these depredations. The white ants enter the cut end and eat away all but the rind. They have there just the conditions which they most need. Mr. Scudder recomnlends, as a preventative, that the trays in which the cut- tings are placed should be lined with slate tiles.
(See Can. entom., v. 19, p. 217-218.)
Mr. S : H. Scudder exhibited under the mi- croscope some of the androconia or scales peculiar to the male sex, which are found in the hesfeyidae. These occur in one or two places on the fore wing, according to which of the two groups into which he has divided the skippers they belong. In one of these groups, the hes'pe~idi, comprising most of the larger skippers, they are found in a special overlapping fold of the wing mem- brane, on the costal border; in the other, the i>am/hiZidi, into which the bulk of the smaller species fall, in a surface dash cross- ing the base of the median riel-vules. In the interior of each is the mass of slender, more or less thread-like scales, which in our New England hes$e~idi take the form of
curving or chain-like, slender, twisted rib- bons, or thread-tipped, tapering scales; the homologous structures of the &zm$hiZz'dz' are the pointed scales or short pile forming the velvety interior of the discal streak. Out- side of all, and partially or wholly concealing the others, are the large tenuous cover-scales, many times larger than the ordinary scales of the wing, with entire margin and con- cave or tortuous surface, While along the edges of the fold of the hes'pendi, or in defi- nite spots about the stigma of the'pam^/tiZidi, are two other sets of scales-a modification of those found along the veins of the costal area-slender, nearly uniform, one, two, or three-toothed, and generally of a very dark color ; and secondly, the very minute boat- shaped scales, which are apparently inter- mingled indefinitely with the others.
The identity of the elements which char- acterize these two forms of male adornment in the skippers has not before been recog- nized, but there is an additional and inde- pendent character in the /amfkilidi in the frequent presence below the area of the dash proper of a large patch of partially erect fan-like scales.
Mr. Scudder also called attention to the difference between the New England species of Thanaos without pre-marginal white
spots on the fore-wing and the others, in that the curving hairs of the interior of the costal fold are replaced in the former: in one case, brizo, by twisted ribbon-like scales ; and in the other, icel-ns, by thread-tipped, tapering scales, very different in general ap- pearance from the curving hairs and wholly lacking the basal crook of these. (See Psyche v. 5. p. 86-88.) Remarks were made by vari- ous members.
Mr. S : H. Scudder then exhibited the in- flated larvae of various diurnal lepidoptera. Dr. G : Dimmock showed a living plant-
louse, Siphonophora 9elargonii hatched 2 Feb.. which had neary completed its full growth.
