tessellate, with numerous large punctures, 

 wanting in tlie middle line ; process of labrum 

 broad, emarginate; antennae fairly long, 

 fiagellum ferruginous beneath towards the 

 tip ; third antennal joint longer than 4 + 5. 

 Mesothorax microscopically tessellate, quite 

 dull, punctured; basal area of metathorax 

 triangular, not bounded bj a ridge, micro- 

 scopically tessellate with a few irregular basal 

 raised lines ; tegulae shining dark brown ; 

 wings smoky, nervures piceous, stigma fer- 

 ruginous edged with piceous ; second sub- 

 marginal cell little narrower above than 

 below, third submarginal narrowed fully 

 half to marginal. Legs black, small joints 

 of tarsi dull ferruginous; hair of legs mostly 

 pale, a black tuft on hind knees, basal joint 

 of hind tarsi broad, with dark brown hair; 

 abdomen oval, convex, shining, microscopic- 

 ally tessellate, with only minute very sparse 

 punctures; first segment fringed at sides and 

 apex with long but not dense white hair ; 

 remaining segments nearly naked, with 

 some white hairs at sides, tending slightly 

 towards band-formation ; fimbria at apex 

 pale brownish-gray. 



I 9 , June 27. It is named after 

 Mr. F. J. Birtwell, the clever young 

 ornithologist who was accidentally killed 

 on the Upper Pecos the day following 

 the capture of this insect. A. birtujclli 

 appears to be related to A. lappotiica, 

 A. frigida and A. convcxa, but is not 

 identical with any of them. 

 ■* Audrena nierrianii, n sp. — 



?. Length about io4 mm., black; pu- 

 bescence all black except on mesothorax, 

 scutelluni and postscutellum, where it is pale 

 ochraceous. Facial quadrangle broader than 

 long; vertex dull, minutely roughened; cly- 

 peus microscopically tessellate, strongly 

 punctured, the punctures sparse in the median 

 line ; antennae short, black, flagellum slightly 



brownish beneath ; first flagellar joint a little 

 longer than the next two together ; process of 

 labrum with sloping sides and emarginate 

 apex ; mesothorax dull, minutely roughened ; 

 enclosure of metathorax ill-defined, minutelv 

 roughened; sides of metathorax with black 

 hair; tegulae very dark brown ; wings smoky, 

 nervures and stigma piceous; third submar- 

 ginal cell long, narrowed more than half to 

 marginal; abdomen shining, microscopicallv 

 tessellate, with sparse punctures at the bases 

 of the hairs ; no hair bands, except black 

 ones on the ventral surface ; fimbria abundant 

 and black. 



One ?, June 27. Named after Dr. C. 

 H. Merriam, in recognition of his valua- 

 ble work on the Hudsonian zone. A. 

 merriami is something like A. anograe'wx 

 miniature. In Schmiedeknecht's tables 

 of palaearctic species, it runs to A. albo- 

 picta, Rad., but is not the same.* 



Ha Hit us virgatclliis, n. sp. — 9 . 



Length about 8 ram.; head and thorax 

 very dark green ; abdomen black with broad 

 white hair bands on the apical margins of 

 the segments; fimbria ochraceous. Facial 



* Tlie following species, closely allied \.qA. merriami, 

 may be made known at the present time : — 



Aitdreitti witshiiigtoiLi, n. sp. — ?. Long, xo\ mm.; 

 differs from merriami as follows : liair of metathorax 

 and upper part of pleura (as well as mesothorax etc.) pale 

 ochraceous (blaclc on lower part of pleura, and pectus), 

 the abundant curled floccus at base of hind legs beneath 

 white, but just anterior to it a tuft of coarse black hairs, 

 strongly contrasting; hair about mouth more or less pale 

 (otherwise the hair of head is all black); first abdominal 

 se^^ment, and middle of second, with long pale hairs; 

 process of labrum short and broad, strongly emarginate, 

 one might say binodose ; tegulae lighter brown ; stigma 

 dark ferruginous ; third submarginal cell less produced 

 apically; tibial spurs light ferruginous; small joints of 

 tarsi, and pubescence of basal joints towards end, ferrugi- 

 nous.
