on long stalk and vein R^ slightly stalked from just above cell ; it 

 possesses however both pairs of spurs on posterior tibiae and would 

 belong, according to Dyar (Proc. U. S. Nat. Mus., 29, 359), in the 

 genus Natada. It seems closely related to A^. dognini Dyar, a species 

 from Columbia. 



Habitat. — Prescott, Ariz, i male. Type, Coll. Barnes. 



Pyromorphid.e. 



23. Triprocris cyanea, new species. 



Entire insect deep metallic blue or green on both sides. Antennae of 

 male strongly bipectinate, of female slightly so. Length of body 8 mm. 

 Expanse of wings, 23-25 mm. 



This species agrees with smithsoniamis Clem., the type of the 

 genus Triprocris, in lacking vein R^ of primaries, differs from it how- 

 ever in having veins R^ and R., stalked and ngt separate. As it 

 possesses the short, untufted abdomen characteristic of the genus 

 we place it here. It is not lustrans Beut., as Mr. Beutenmiiller has 

 kindly compared it with his type and tells us it is a much smaller 

 insect in every way. 



Habitat. — Santa Catalina Mts., Babaquivera Mts., Ariz. (July). 



Described from 8 males, 6 females. Types, Coll. Barnes. 



24. Harrisina brillians, new species. 



Entire insect dark metallic blue, often shading into green ; abdomen of 

 male tufted laterally and posteriorly ; antennae in both sexes bipectinate. 

 Length of body, 1 1 mm. 



Expanse, 29 mm. 



This is the species described by Dyar (Proc. Ent. Soc. Wash., 

 1901/2, p. 327) under the name pf coracina Clem. The true cora- 

 cina, however, of which we possess 7 specimens from the type local- 

 ity, Texas, has no trace of metallic lustre, being simply pure black, 

 just as Clemens stated. Gingla marteni Frch. which Dyar is in- 

 clined to consider synonymous with coracina is entirely different, 

 being broader and shorter winged and possessing a venation ap- 

 proaching that of Triprocris but with all veins present on fore-wing. 

 In our species, as in the generic type, amcricana, veins R,, R, and 

 R^ of fore-wing are stalked. 



Habitat. — Palmerlee, Redington, Yuma, Ariz. (July) ; Colo. 

 (Bruce) ? 7 males, 6 females. Types, Coll. Barnes.
