HlSTERIDiE. — HISTER. 149 



Glossy-black ; thorax with the lateral striae reaching to the base, where it is 

 slightly recurved : elytra with six striae, the two inner abbreviated, the one 

 nearest the suture being the longest: legs and antennae rufo-ferruginous ; 

 anterior tibiae quadridentate. 



Resembles the last in size and habit, but differs in having the legs and antennae 

 rufo-ferruginous, with the anterior angles of the thorax less produced and 

 destitute of the abbreviated curved striae; the anterior tibiae are also quadri- 

 dentate. 



More abundant than the last, but apparently rare : I possess 

 specimens captured within the metropolitan district. 



Sp. 12. Nigrita. Suhohlongus, ater, elytris sex striatis, duabus interioribus ab- 

 breviatis, tibiis anticis quinque dentatis, dente extimo bifida. (Long. corp. 

 2 lin.) 



Hi. Nigrita. Steph. Catal. 101. No. 1064. 



Rather oblong, deep black, slightly glossy : thorax with the lateral line straight 

 and rather approximating to the margin; elytra each with an abbreviated 

 stria next the suture, about half their length, then a second about one-third 

 the length of the former, followed by four entire ones on the disc, the margin 

 without striae : legs black ; the anterior tibiae with five denticulations, the 

 outer one bifid : antennae black : mouth piceous. 



The want of the marginal stria on the elytra distinguishes this insect from Hi. 

 carbonarius, which it somewhat resembles, but the striation of the elytra is 

 different. 



Of this insect I possess specimens captured near London by my- 

 self, but I know not the exact locality. 



2. Elytra with a marginal stria. 



Sp. 13. stercorarius. Obion go-ovatus, ater, nitidus, elytris stria laterali brevis- 

 simd, tribus exterioribus integris, internis tribus abbreviatis, tibiis anticis 

 quadridentatis. (Long. corp. 2 — 3 lin.) 



Hi. stercorarius. Ent. Hefte.— Steph. Catal. 101. No. 1056. 



Oblong-ovate, black, smooth, very glossy: frontal stria rather deeply punctured : 

 thorax with the lateral stria somewhat remote from the margin and reaching 

 to the base : elytra a little dilated on the sides, the apex of each slightly 

 rounded, each with a small lateral stria, abbreviated at each end, then three 

 entire simple slightly curved ones, and three abbreviated ones within at the 

 apex, the sutural one being the longest : body pitchy-black beneath : breast 

 deeply punctured : antennae and legs black, the anterior tibiae much dilated, 

 with four robust teeth, the intermediate stoutest. 



The very glossy upper surface of this species, with the brevity of the lateral 

 stria on the elytra, the four-toothed anterior tibiae, &c, distinguish it from 

 the following. 



Not uncommon in the vicinity of London, and I believe in other
