latter a little longer than broad; in hind wings cubital ends a long 

 way before the fork of median. Thorax, abdomen, and legs with 

 long black hair, especially noticeable on the metanotum, femora, and 

 coxae beneath; front with very short hair. Tibial spines numerous 

 and stout. Length 11 ram. 



Planiceps assimilis, sp. nov. 



TyiK'.— U. C. Z. 10,009. Brit. Columbia: Penicton, August. 

 J. B. Wallis. One specimen. 



9 Related to P. hirsvhis, but differs in having the pronotum fully 

 as broad as long. Black, with blue or violaceous reflection; the 

 antennae very short, the third joint as short as in P. hirsutus; face 

 with erect bristles, vertex straight across; pronotum fully as broad 

 as long, plainly angulate behind in middle, the metanotum with 

 appearance of a median line which, however, is not present, abdomen 

 moderately slender, subcompressed, hairy near tip, mid and hind 

 tibia with stout spines as in P. hirsvtus, the inner spur of hind tibia 

 one half the length of basitarsus; thorax with hair plainly shorter 

 than in P. hirsutvs the legs also less hairy than in that species, but 

 more hairy than most species of the genus. Venation as in P. hirsutus, 

 except that the second submarginal and especially the second dis- 

 coidal cells are longer than in P. hirsutus. Length, 1 1 mm. 



Pedinaspis anomala, sp. nov. 



Typr.— M. C. Z. 10,010. Texas: Coryell Co., G. Birkmann. 

 One specimen. 



9 Black, with purple reflections on body, wings a uniform black. 

 In general very similar to P. vicina Cress. The antennae shorter 

 than in that species, the ocelli smaller and farther apart, the lower 

 margin of clypeus truncate, almost concave, metanotum short, the 

 posterior surface more declivous than in P. vicina; legs with spines 

 rather smaller than in P. vicina, inner spur of hind tibia nearly one 

 half the length of the basitarsus, all femora with fine, short hairs. 

 Venation in the single specimen may be abnormal in having but two 

 submarginal cells, the second long and receiving both recurrent veins; 

 the third discoidal cell very short, more so than in P. vicina, and the 

 basal vein at base of first discoidal cell is strongly bowed basally, and 

 is interstitial with the cubital cross-vein. In P. vicina the basal 

 vein shows an even curve. Length, 15 mm.
