OF WASHINGTON, VOLUME XVII, 1915 135 



Female. Length 15 mm.; antennae 12 mm. Differs from virginiensis 

 Gush, as follows: antennae black with an obscure indication of a pale 

 annulus about two-thirds of the way to tip; tapering apically, flagellum 

 45-jointed (in type of virginiensis tips of antennae are broken off) ; propo- 

 deum with middle area transversely rugose at top of posterior declivity, 

 spiracle rather large oval (in virginiensis the spiracle is small and round) ; 

 scutellum and postscutellum, tegula; and spots in front and below, yellow; 

 hind coxa; black, front and middle coxae yellow, testaceous at base; all 

 trochanters yellow, those of hind legs somewhat darker; front and middle 

 femora testaceous, yellow at base and apex; hind femora black, yellow 

 at base and apex; front and middle tibiae and tarsi pale testaceous, the 

 tibise yellow at base; hind tibiae yellow at base, black at tip, their tarsi 

 yellowish, the joints apically infuscate; abdomen piceous-black with 

 apical segments and ovipositor yellowish; first tergite apically, second 

 entirely, except an obscure dark spot on each side of middle, and basal 

 half of third testaceous; first tergite similarly though less coarsely sculp- 

 tured, its sides arcuately divergent beyond the spiracles (in virginiensis 

 the sides beyond the spiracle are at first concave then arcuate); second 

 tergite with carinac weak, more finely punctured; remaining tergites pol- 

 ished, minutely punctured. 



Type locality: Cornwall, Idaho. 



Type: Cat. No. 19299, U. S. N. M. 



A single specimen taken by C. V. Piper on August 1, 1898. 



(Monoblastus) Trematopygus caliroae (Viereck). 

 The types of Monoblastus caliroce Vier., described from speci- 

 mens reared by the present writer from Caliroa cerasi, run in 

 Davis's table to this genus, and agree very well with his descrip- 

 tion of fusculosus Davis. Davis's description is based on the 

 male sex only. Before me are the two females and the male 

 of the type series of caliroce Vier. together with a male and a 

 female taken by me on cherry trees badly infested with pear 

 slug at North East, Pa. The males have all of the characters 

 mentioned in the description of fusculosus and in addition have 

 the apical tergites somewhat infuscated. The females differ 

 from the males in having the wings somewhat paler, the first 

 tergite red except the extreme base and the caring, the apical 

 tergites red, and the pale color of the coxa?, mandibles, trochan- 

 ters and tegulse more reddish. 



Trematopygus eriocampoididis n. sp. 



In Davis's table to the genus this species will run to fusculosus Davis, 

 but differs from that species and caliroce (Vier.) in having the abdomen 

 entirely black. 



Female: Length 5 mm.; antennae 6 mm. Face polished, sparsely, min- 

 utely punctured, and with a very small, rounded tubercle medially below
