Dolerns similis, var. yultonensis, Norton. 



This species from Alaska is a little smaller than specimens from the 

 Atlantic Coast, but agrees with them precisely in form and sculpture. 

 The difference in color may be specified as follows : — In similis, the 

 thorax is black, with the anterior angle and anterior lobe of mesotho- 

 rax partly rufous. At times the anterior angles are black. In variety 

 yukonensis the whole thorax is black, but in one specimen the anterior 

 angle is rufous. A % specimen has the mouth pale and the basal half 

 of the two hinder tibiae yellow. The inner claw tooth is stouter in the 

 9 and rather more feeble in the % than in similis. 



Dolerns riistinetus, n. sp. 



9-— Length 0.28; br. wings 0.56 inch. Eather short and stout; head and 

 thorax coriaceous, with coarse punctures, the whole of pleura coarsely pitted, 

 the pits of equal size on the pro- and metapleura, as in middle ; about half as 

 large as in similis; body with quite sparse whitish hair. Color black; tegulae, 

 prothorax, a spot in middle of anterior lobe of mesothorax, a band across side 

 lobes from scutellum to wings, a stripe across the metapleura from anterior 

 wings, and a band across the apical half of segments 2 — 5 of tergum, yellow- 

 red ; legs apparently all of one color; wings blackish-hyaline. 



San Francisco, California. (H. Edwards.) One specimen. 



Dolerns eoeeinifera, n. sp. 



9. — Length 0.50; br. wings 0.95 inch. — Head back of ocelli polished; face 

 about and beneath ocelli very coarsely punctured ; labrum subpolished ; nasus 

 incurved; mandibles punctured above; remainder of body polished, except 

 the pleura, which is coarsely pitted ; inner spur of anterior tibiae bifid ; claws 

 with a strong inner tooth near middle. Antennae, head, a V on anterior lobe 

 of mesothorax, scutel, metathorax, basal plates, pleura, pectus, terebra sheath 

 and legs, black; mesothorax, anterior angle, neck and abdomen coccineous; 

 spurs yellowish; wings violaceous, obscure, nervures black, a clear spot at ex- 

 treme base of wings, lines leading to the bullae clear; first submarginal cell 

 nearly circular and much contracted at the cross-nervure. 



Near San Francisco, California. (H. Edwards.) Several specimens. 

 This fine species seems to be a variety of tejonensis, from which it dif- 

 fers in having the clypeus notched and the pleura more coarsely pitted, 

 and the scutel, metathorax and pleura black. 



Selandria Snmiehrasti, n. sp. (Sec. 1, Tribe 1.) 



9- — Length 0.25; br. wings 0.50 inch. Rather stout; antennae moderately 

 swelled in middle, the four apical joints diminishing in size and length, final 

 joint pointed ; no sutures at sides of ocelli, a lengthened pit back of each upper 

 ocellus, three little pits back of antennae; nasus wide, margin subsinuate, a lit- 

 tle protuberant in middle ; surface shining, covered with whitish hair; inner 

 claw tooth near the tip, long, appearing bifid. Color of head back to neck, pro- 

 and mesothorax, scutel, tegulse and collar, yellow- red; remainder of body shin- 

 ing black; three little dots back of antennae, cheek, labrum and palpi, black; 

 legs black, the two or three basal joints of tarsi clear white ; wings subobscure, 

 blackish, lower half of stigma brownish ; first submarginal cell rather long, se-
