new r/enera and species of Coleoptera. 19 



with them some Asiatic species, which differ in having 

 the elytra more or less delicately striated, and three of 

 them being of a broad form. 



Parygrus Erichsoni, sp. nov. 



Elongatus, nigro-piceus, snbnitidus, parce longe pn- 

 bescens; fronte impressa; thorace longitudine paululo 

 latiori antice paulo angustato, crebre subtiliter punctvilato 

 (punctis majoribus sat crebre interspersis), brevissime 

 hand dense pubescenti, angulis posticis acutis. Scutello 

 cordiformi. Elytris basi thorace vix latioribus et triplo 

 longioribus, postice paulo ampliatis, ad apicem arcuatim 

 attenuatis, convexis, parce longius pubescentibus, fortiter 

 punctato-striatis, interstitiis sat angustis nitidis, con- 

 vexiusculis. Antennis flavescentibus, basi piceo, articulo 

 primo obconico, secundo majore fortiter auriculato. Tibiis 

 tarsisque piceis. 



Long. 2| lin.; lat. 1 lin. 



The general form is that o^ Parnus prolifericornis, but 

 it is much more elongate and narrower, and it is not densely 

 clothed v/ith pubescence. The head is a little broader, 

 the forehead convex with a shallow impression on the 

 vertex; the pubescence on the eyes is longer than in that 

 species. The thorax is rather narrower, a little more 

 convex, the sides are gently arcuate, the anterior angles 

 are acute, the posterior angles acute and very slightly 

 divaricate and are impressed above. The stride of the 

 elytra are deep and the punctures large ; the interstices 

 are somewhat narrow and gently convex, with scarcely a 

 trace of punctuation. The 2nd joint of the antennas is 

 large, produced and recurved anteriorly. Of the branches 

 emitted by the 3rd to 10th joints that of the 4th is the 

 longest ; those of the following joints gradually become 

 shorter, the 11th joint is conical. 



Hah. — Columbia. Brit. Mus. 



Parygrus Hardivicki, MacLeay. 



This species is described by MacLeay as a Dryops, but 

 its structure is quite different from that genus. 

 Hah. — Java. Type in Brit. Mus. 



Parygrus indicus, sp. nov. 

 Elongatus, convexus, niger, nitidulus, griseo-pubescens. 

 Capite convexo ; antennis piceis. Thorace longitudine
