PSYCHE. 



129 



cal shield large, exposed, dark brown and 

 nearly naked. Color grayish like dead 

 leaves, a narrow, dark brown dorsal line. 

 Warts low, flat, but large in three rows. 

 Hairs rather pale, but in general concolorous, 

 stiff, sharp-pointed with clear basal bulbs. 

 Under a high power the spinules are seen to 

 form equidistant rings making the hair ap- 

 pear segmented. Skin densely minutely 

 spinulose. The large pale warts give the 

 appearance of broad, faintly paler subdorsal 

 and lateral bands, separated by the straight 

 dorsal and broken lateral brown lines which 

 gradually become defined. 



Stage IV. Head light brown, eye black; 

 widtli .8 mm., retracted under the large, dark 

 brown cervical shield. Body as before, the 

 large flat warts pale, the ground color only 

 showing as narrow chocolate brown dorsal 

 and subdorsal lines, pale between the seg- 

 ments. Shaft of hairs segmented, the tips 

 black, the bulb at the extreme base, small. 



Stage V. Width of head i.i mm., as 

 before. Warts brown in large pale gray 

 areas which cut up the dark brown ground 

 into straight dorsal, wavy subdorsal and 

 broken stigmatal bands; subventral region 

 pale brown; incisures dark, obscurely con- 

 necting the bands. Joint 2 pale in front, dark 

 behind covering the head. Feet pale. On 

 thorax warts i, ii, iii, iv-|-vand vi are present. 



on abdomen i-J-ii, iii, iv-(-v, vi and leg-plate. 

 Hairs segmented, sub-barbuled with basal 

 bulb which shrinks to an annulus at the end 

 of the stage. The whole color becomes dark 

 purplish at this time. 



Stage VI. Head pale brown, lighter in 

 the sutures; width 1.6 mm. It is retracted 

 in the hood of joint 2, which is large with a 

 large, dark brown, bisected cervical shield. 

 Body thick and robust, not tapering, densely 

 short hairy. Hairs segmented, with basal 

 bulbs as before, well developed. Color dark 

 velvety brown, reduced to a series of longi- 

 tudinal and transverse lines by the large, 

 rounded and slightly oblique pale gray areas 

 which surround the upper three warts (i, ii-|- 

 iii, iv-j-v on thorax, i+ii, iii, iv+v on abdo- 

 men). The warts themselves are brown, 

 forming dark centers to the pale patches, not 

 so dark as the ground color. Hairs on lower 

 side of third wart (iv+v) longer, concealing 

 the subventral region. Feet pale. Spiracles 

 brown, the one on joint 5 moved up. A cir- 

 cular, pale, eversible area surrounds the spir- 

 acle on joints 6 and 1 1. 



Cocoon. This is irregular, like Harrisina 

 but larger, the main web brownish, a little 

 wrinkly and opaque with some white floss 

 silk outside. Size 13x6 mm. Spun between 

 leaves on the ground. 



DESCRIPTIONS OF TWO NEW FOSSORIAL WASPS. 



BY WILLIAM H. ASII.MEAD, WASHINGTON', D. C. 



The two new fossorial wasps described 

 below were discovered by Prof. George 

 W. Peckham in Wisconsin, who will shortly 

 describe their habits and life histories. 



(i) Astata leuthstromi, n. sp. ?. — Length 

 8 mm. Entirely black, shining, and sparsely 

 clothed with a whitish pubescence. Head 

 rather closely punctate, the clypeus truncate 

 anteriorly and fringed medially with some 

 black hairs, on either side of which are long 

 glittering white hairs; palpi rufo-piceous : 

 first joint of flagellum about i longer than the 



second, joints 2-4 subequal, about four times 

 as long as thick. Mesonotum anteriorly 

 finely punctate, posteriorly for at least half 

 its length as well as the scutellum highly 

 polished and with only a few minute scat- 

 tered punctures; mesopleura punctate, closer 

 and more distinctly so posteriorly; meta- 

 thorax with a smooth impunctate space at 

 base, confluently or regularly punctate poste- 

 riorly. Wings towards base hyaline, the 

 apical half subfuliginous ; the marginal cell 

 is about as long as the first submarginal
