PSYCHE. 



[October 1897. 



cell ; the transverse cubital veins are usually 

 subangulately broken with more or less of 

 a distinct stump of a vein issuing from the 

 angle (the right wing has the third submar- 

 ginal cell nearly divided into two cells by 

 a spurious cross-vein from the angulation 

 in the second transverse cubitus). Abdomen 

 apparently smooth, impunctate, but with a 

 strong lens the surface exhibits a fine or 

 microscopical reticulation from very fine 

 lines. 



Hab. — Haitland, Wis. 



Type, No. 3716, U. S. N. M. 



This species is allied to A. occidentalls Cr. 

 but is readily distinguished by its smaller 

 size, the color of the wings, by the venation 

 and by the smoothness of the mesonotum. 

 Its resemblance to A. unicolor Say. is only 

 superficial. 



The species has been named in honor 

 of Dr. Leuthstrom, father-in-law of Prof. 

 Peckham, in whose garden the species was 

 found. 



(2) Plenoculus feckhatni n. sp. J. 

 Length 3 to 3.5 mm. Black, closely punc- 

 tate and clothed with a sparse whitish pube- 

 scence, the face from middle of eyes and the 

 clypeus with a dense silvery pubescence. 

 Clypeus with a median ridge and produced 

 into a small conic median tooth at apex. 

 Mandibles black, the basal two-thirds closely 

 opaquely punctate, the apical half smooth, 

 shining. Palpi brown-black. Antennae 13- 



jointed, the flagellum gradually incrassated 

 towards tip; the first joint of the fiagellum is 

 scarcely as long as the second, the third and 

 fourth a little longer than the second and 

 stouter, the joints beyond to the 13th gradu- 

 ally shortening, joints 7-10 being transverse ; 

 the terminal joint is large, conic-ovate, as long 

 as the three preceding united. Metathorax 

 riigulose with two short median carinae in a 

 slight depression just before the posterior 

 face. Wings hyaline, faintly duskj' at apical 

 margins, the tegulae, stigma and veins brown- 

 black, the marginal cell is sublanceolate 

 with the extreme apex truncate and with an 

 appendage; the second submarginal cell is 

 triangular, petiolate, the second recurrent 

 nervure entering it a little beyond the mid- 

 dle. Hind tibial spurs and the three basal 

 joints of tarsi, whitish. Abdomen long, 

 ovate, a little longer than the head and 

 thorax united, subopaque, finely punctate, 

 sericeous, except lateral triangular spaces, 

 separated by a grooved line, on second, third 

 and fourth dorsal segments, which are smooth 

 and shining 



Hab. — Haitland, Wisconsin. 



Type, No. 3717, U. S. N. M. 



Qiiite distinct from all other species de- 

 scribed in this genus by Mr. Fox, by the 

 apical median clypeal tooth. 



Prof Peckham informs me this species 

 preys upon a Lygaeid belonging to the 

 genus Pamera. 



THE LARVA OF CYDOSIA. 



It will be remembered by lepidopterists 

 that the position of the genus Cydosia 

 Westw., has been in dispute. In Smith's list 

 of 1891, it appears in a subfamily Cydosiinae 

 of Arctiidae. I have just learned from my 

 friend Mrs. E. M. Swainson that she has 

 discovered the larva in Jamaica, and she sends 

 me some notes on the subject, along with a 

 specimen of the moth. The particular spe- 



cies sent — the only one known to occur in 

 Jamaica — is C. submutata (Walk.) Ckll., 

 Journ. Inst. Jamaica, 1S93, p. 259 (= C. 

 /amaicensis Ckll., Journ. Inst. Jamaica, 1892^ 

 p. 135, = C. nobilitella (not Cram.) Butler ex 

 err., P. Z. S., 1S78, p. 495). I give the 

 account of the larva in Mrs. Swainson's own 

 words: — -"A pretty half looper larva, one 

 inch and a half long, soft velvety black with 

 orange marks all down back and at sides, 

 between these are tiny pale yellow marks, on
