April, 1917 Bulletin of the Brooklyn Entomological Society 15 



Antennae all black; cephalic femora much swollen. Funicle 

 joints unequal, 2 largest, twice longer than wide, the club 

 apparently 4-jointed with a lateral terminal spine which is 



curved at apex and hairy similis new species. 



Wings with a large, ovate fuscous area against the marginal vein. 

 Postmarginal vein distinctly shorter than the marginal. 

 Funicle joints all wider than long, widening distad; club 

 solid, obliquely truncate, with no terminal spine. Segment 

 2 of abdomen occupying over a third of the surface. Man- 

 dibles tridentate. Cephalic femora a little swollen. Pro- 

 podeum tricarinate at the meson, the space occupied by the 

 carinse barely wider than the space between them and the 



lateral carina (male) maciilipennis Ashmead. 



Euchrysia similis Girault. Female : — Like hyalinipennis except as de- 

 scribed above. One ? in the U. S. Nat. Museum from Lawrence, Kan., 

 June 18, i8g6 (Hugo Kahl). 



Type. — Catalogue No. 20,464, U. S. N. M., the specimen 

 minutien-mounted, a fore and hind leg and an antenna on a slide 

 with the type appendages of hyalimpennis. 



THE ELEVENTH PLEOCOMA. 



By H. C. Fall, Pasadena, Cal. 



Pleocoma badia n. sp. — Form robust, nearly as in fimbriata and conjun- 

 gens; color brown both above and beneath, hairs of under surface yel- 

 lowish brown. Antennae with the third joint elongate, fourth either with 

 a short lamellate process or merely angulate, fifth to eleventh with long 

 lamellae, that of the fifth joint distinctly shorter than those following. 

 Clypeus deeply notched, vertical horn emarginate at tip. Prothorax twice 

 as wide as long, form as in conjungens, antero-medial area flattened and 

 medially impressed or concave, surface finely, rather sparsely punctate, the 

 flattened and impressed area conspicuously more coarsely and densely so 

 and with numerous long hairs anteriorly. Elytra still more finely and 

 sparsely punctate than the prothorax, the geminate lines only feebly 

 defined. 



Length 26-28.5 mm., width 14.5-15 mm. 



Described from three males given me by my young friend 

 Alonzo Davis, of Pasadena, who took them December 19, 1914, 

 at an elevation of about 3,000 feet on the Mt. Wilson trail (So. 

 Cal.), and who has recently published an account of their capture 

 in this Bulletin (February, 1916).
