Utah (southwestern)— Mr. Weidt parvicollis, n sp 



Pronotum very coarsely punctate and glabrous or very nearly so. 

 the surface not deeply impressed along the apical margin, at 

 least toward the middle; antennae much stouter, darker in color 



than in any other species. New Mexico spiculum Csy. 



6 — Prothor.ix large,ti*ansverse, the lateral process long, slender, finely 

 aciculate and abniptly formed, the surface unusually convex 

 longitudinally, very coarsely and somewhat sparsely punctate 

 and glabrous, with short erect hairs toward the sides only ; an- 

 tennas slender and filiform. California (Mt. Diablo). 



piLOSicoRNis Csy. 



The sexual characters are very feeble in this genus, and there 

 is a strong and persistent similarity of type throughout ; the 

 male characters evince themselves, however, in the slightly 

 longer antennae, with more elongate outer joints and in the 

 rather more dilated tarsi. In harrisi there is a large transverse 

 discal area of the pronotum, which is very finely and densely 

 punctate, and of which there is no trace in the female or in 

 the male of sodalis. Pilosicornis is the most aberi-ant species 

 of the genus, and is wholly isolated from the other five in 

 many very radical structural characters. 



ON THE SMALLLST PYROMORPHID AND ITS LARVA. 



By Habbison G. Dyab. 



The smallest known P^romorphid is the Cuban genus, Se- 

 tiodes H.-S. I have met with a form of this in the Bahamas, 

 which I describe herewith : 



Genus Setiodes H- S. 



1S66— Setiodes Herrich-Schaffer, Corr.— Blatt rain. zool. ver. Re- 

 gensb., XX T06. 



1867— Formiculus Grote, Proc. Ent. Soc. Phil., vi, 184. 



Palpi rudin^entary ; antennae pectinate, the tern»inal pectinations 

 thickened, the whole organ somewhat short and slightly clubbed ; 

 legs without spurs: wings very long and narrow, more so than in 

 Harrisina, the hind wings especially reduced; fore wings with 11 

 veins, vein 9 absent, 10 and 11 stalked, the rest arising separately 

 from the cell, which is divided by the distinct discal vein; hind 

 wings with very small internal area, the internal veins all lacking^ 

 veins 2 to 7 evenly spaced from the cell, 8 absent, 2 and 3 short and 

 down curved. 



The peculiar genus has two species, or local forms, separable ag 

 follows; 



Hind wing with a white spot; spot of fore wing large. ..nana, H. S. 

 Hind wing entirely black; spotoffore wing small. .bahamensi8,n. sp.
