:;. DRYOPHANTA EMORYI, new species. 



(hdl. — A small, brown, tliiii-slielled, semiglolnilar gall, attached by 

 a small ])()iiit to the upper or under snrface of a leaf of (/uercus emoriji. 

 Internally there is a small, central kernel, held in place by delicate 

 filamentary fibers. Diameter, 2 to 3 nun. 



Gallfly. — Female, length, L' mm. Form rather slender, polished 

 black; aiitenn;e and legs dark brown, almost black, the articulations 

 and tarsi dark houey-yellow or slightly reddish. The head and thorax 

 are covered with long- sparse pile; lower part of face with some coarse 

 punctures, and a jjoorly defined median ridge. The antenna' extend to 

 base of the abdomen, j)ubescent, 14-joiuted, the third joint more tlau 

 oue-third longer than the fourth: flagellar joints three, four, five, and 

 six, are rounded at apex; the others are short, slightly widened and 

 truncate at apex, but narrowed and rounded at base, the terminal joint 

 one-third longer than the preceding, fusiform. 



The thorax has two broad, distinct, parapsidal grooves; scutellum 

 minutely rugose, elevated and rounded posteriorly, but with a small, 

 smooth, shining spot on the disk; at base it is transversely depressed 

 and apparently without the usual fove;e; if they exist they are small. 

 The mesopleura are smooth, shining, but when carefully examined a 

 few stria^- can be detected anteriorly and basally. The abdomen is 

 large, polished, longer than the head and thorax together, compressed, 

 and, when viewed from the side, obovate in outline; the ventral valve 

 projects considerably, and is armed and hairy. Legs rather densely 

 jiubescent. Wings long, hyaline, pubescent, the veins strongly devel- 

 oped, dark brown, slightly piceous.

Three specimens, reared ])ecember 13, 1880, from the above-described 

 gall; collected by Mr. H. H. Kusby, at Silver City, New Mexico. 



1. DRYOPHANTA PULCHRIPENNIS, new species. 



Gall. — The s])ecimens of the gall from which this species was reared 

 can not now be found in the collection, but the following description of 

 it, taken from the department records, may assist in its identification: 



lieceived from Mr. 11. H. liusby, from Arizona, a leaf of au midtstermiued oak 

 with six galls ou its under surface; four of these are iu a row in the middle between 

 the midrib and the margin; they are light brown, almost hemispherical, subopa((ue, 

 reticulate, and with scattered, very miunte, reddish tubercles, which have some 

 short white hairs basally. 



Gallfly. — Female. Length, 1.8 to 2 mm. Brownish yellow, the second 

 abdominal segment apically dark brown. In one of the two specimens 

 in the collecti(m,the mesonotum, scutellum, and metathorax are brown- 

 ish; eyes, ocelli, and ungues dark brown. Head, thorax, and pleura 

 smooth, shining; the head much wider than the thorax and thick 

 antero-posteriorly. Antenme about as in D. emoryi, the l\)uiteenth 

 joint, however, not being distinctly separated from the thirteenth,
