DolerilS distinctllS Norton, Trans. Am. Ent. Soc. iv, 82.—" 9.— Length 



0.28: br. wings O.od inch. — -Rather 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 ; 

 bod}^ with quite sparse whitish hair. Color black : tegulse, prothorax, a spot in 

 middle of anterior lobe of niesothorax, a band across side lobes from scutelluin 

 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." 

 Hub. — San Francisco, California. 



Dolerus coccinil'era Norton, Trans. Am. Ent. Soc. iv, 82. — " 9 -—Length 

 0.50; br. wings 0.95 inch. — Head back of ocelli polished; face about and be- 

 neath 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 tibise 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 extreme base of 

 wings, lines leading to the bullae clear; first submarginal cell nearly circular 

 and much contracted at the cross-nervure." 



Ilab. — Near San Francisco, California. This fine species seems to 

 be a variety of tejonensis, from which it differs in having the clypeus 

 notched and the pleura more coarsely pitted, and the scutel, meta- 

 thorax and pleura black." 



Heniichroa albido-variata Norton, Trans. Am. Ent. Soc. iv, 81.— 

 " 9 • — Length 0.35 ; br. wings 0.70 inch. — Color black, the edge of nasus, labrum, 

 tegulse, collar, anterior angle, a stripe on each side of anterior lobe of thorax, 

 and a band across four basal segments of tergum, wax-white; edges of the 

 three apical segments waxen ; legs whitish, a black band on the hinder femora 

 and the hinder tarsi blackish above. Antennae moderate, not slender, filiform, 

 joints of nearly equal length and size. The two basal joints very short and 

 deeply set, third rather the stoutest: lower ocellus in a deep basin, nasus deeply 

 notched; lower half of face and the pleura with cinereous hairs; remainder 

 of body shining; the head nearly as wide as thorax; body quite thick and 

 stout; the first tarsal joints rather arcuate, with processes beneath. Claws 

 cleft; wings hyaline, faintly smoky, stigma and costal nervure brownish; 

 second submarginal longest, receiving the two recurrent nervures, third of 

 nearly equal width; lanceolate cell contracted; the under wing with two inner 

 cells, lanceolate cell retracted." 



Hah. — Texas. (Coll. Am. Ent. Soc.) 



Hemichroa fraternalis Norton. Trans. Am. Ent. Soc. iv, 81. — "%. — 



Length 0.30; br. wings 0.60 inch. — Shining black, more slender than albido- 

 variata; tegulae and anterior angle piceous; legs pale, with the basal one-third 

 of femora and the coxae black, hinder legs mostly black; sculpture and wings 

 as in albido-variata, of which it is very probably the male."
