HYLURGINI. 389 



2. H. longus, n. sp. 



Slender, cylindrical, black, nearly glabrous. Head densely punctured, 

 beak finely carinate, front with a transverse impression. Prothorax longer 

 than wide, base and hind angles rounded, sides sliglitly rounded, converg- 

 ing graduall}' to the tip, which is broadly rounded; punctures deep and 

 strong, larger at the base than at the tip and sides, where the^^ are also 

 more dense; no smooth dorsal line is visible. Elytra less shining than the 

 prothorax, with striai composed of moderate sized, punctures; interspaces 

 nearly fiat, wider than the striip, densely, finely punctured. Club of an- 

 tennae brown, first joint composing about one-half of the mass. Length 4.5 

 mm.; .175 inch. 



Colorado, Prof. F. H. Snow; one specimen. This species resembles closely 

 H. macer, but can be easil}^ recognized by the different form of the pro- 

 thorax. 



The following synonyms will complete the bibliography I have already 

 given in my synopsis. 



4. H. porculus Er. "Wiegm. Archiv. 1831), i, 49 ; U. carbowirius Fitch, 

 Noxious Ins. New York, 4th report, No. 249 ; //. granosus Chapuis, Mem. 

 Soc. Roy. Sc. Liege, 1869, 73 ; //. scabripennis Zimm., Tr. Am. Ent. Soc. 

 1868, 149; ? H. salebrosus Eichhoft, Berl. Ent. Zeitschr. 1868, 146. 



5. H. cavernosus Zimm., 1. c. 149 ; ? H. scobinosu^ EichhofT, Berl. 

 Ent. Zeitschr. 1868, 146 ; Chapuis, 1. c. 73. 



EichhofT gives Carolina as the locality ; Chapuis mentions Norfolk 

 Sound, which, being on the Pacific coast; makes the reference doubtful. 

 Perhaps the specimen came from Norfolk, Virginia, instead of Norfolk 

 Sound. Should they prove to be the same, the name proposed by Eichhofi" 

 has prioi'ity by a few weeks. 



9. H. exilis Chapuis, 1. c. 20. 



Florida, one specimen, Messrs. Hubbard and Schwarz. Nearly related 

 to //. tenuis, but the prothorax is more coarsely punctured, and the inter- 

 spaces of the elytra are not granulate, but rugosely punctured, and less 

 opaque. Length 2.5 mm. ; .10 inch. 



HYLURGOPS n. g. 



I have separated as a distinct genus the species referred to Erichson's 

 sec )nd division, having the third tarsal joint broader and bilobed, and the 

 mesosternum protuberant. They are-, quite different in form from true 

 Hi/lastes, and resemble DjiidroctowK, the prothorax: b?ing m )re narrowed 

 forwards, and more finely and denscdy punctured. The basal margin of 

 the elytra is so acutely defined in II. granulatwi and pinifex that I should 

 place them near Hylurgus, but for the scutellum, which is not depressed ; 

 and for the deeper antennal grooves, which remove them from the group 

 of Ilyluffii. The front tibiae are less coarsely serrate than in Ilylastes. 



The species may be thus distinguished : 



Prosternal ridges acute ; front transversely impressed. 2.
