Leptacinus.'\ staph YLiNiDiE. 293 



sparingly punctured at the sides, forehead very large, strongly furrowed, 

 the lateral furrows prolonged ; antennoe short, obscurely red with the 

 first joint lighter, joints 4-10 transverse ; thorax oblong, narrowed 

 behind, with two dorsal series consisting of live large punctures, of 

 which the two anterior ones are often placed at some distance from the 

 others ; the lateral series are also composed of five punctures ; elytra as 

 long as thorax, with three somewhat indistinct rows of punctures ; hind 

 body finely and sparingly punctured ; legs red with the tarsi lighter. 

 L. 5-6 mm. 



Male with the seventh segment of hind body broadly emarginate at 

 apex, segment of armature somewhat projecting, split longitudinally, and 

 sometimes gaping open. 



In haystack refuse, stables, duug-heaps, &c. ; local ; Lee, Darenth Wood, Sheerness, 

 Chatham, Forest Hill, Esher, Birdbrook, Ealing, Toubrkige ; Kingsgate ; Devonshire ; 

 Birmingham district; Repton, Burtou-ou-Trent ; Northumberland district, not 

 common; Scotland, not common, Tweed, Dee, and Moray districts; Ireland, near 

 Dublin. 



Zi. batychrus, Gyll. Smaller and narrower than the preceding; 

 the head is a little more oblong and is less strongly, but more thickly, 

 punctured on the sides ; the large number of tine punctures (12- 

 14) in the dorsal series of the thorax will, however, at once dis- 

 tinguish it ; the apical half of the elytra is usually testaceous (although 

 sometimes specimens occur in which they are unicoloruus), and the 

 elytra are more finely punctured ; the hind body is a little more dis- 

 tinctly punctured especially at the sides. L. 4|-5 mm. 



In dung-heaps, haystack refuse, and vegetable refuse generally ; local, and dis- 

 tributed much as the preceding; London district, not uncommon; Glanvilles 

 Wootton ; Devonshire; Markfield, Leicester ; Cromer; Knowle, near Birmingham; 

 Eepton ; Liverpool ; Northumberland distiict, not common ; Scotland, not common, 

 Dee and Moray districts; Ireland, near Dublin. 



Ii. linearis, Grav. This species so closely resembles the preceding 

 in structure that it is by many authorities considered as merely a variety ; 

 it is, however, considerably smaller ; the head is less oblong, a little 

 less thickly punctured on the sides, with the central smooth space a 

 little larger ; the antennae, as a rule, are darker ; the dorsal seiitvs of 

 thorax are composed of fewer punctures ; the elytra are almost always 

 entirely dark, sometimes a little lighter at their apical angle ; the male 

 characters are also different, the seventh ventral segment of hind body 

 being less emarginate. L. 4 mm. 



In hotbeds, vegetable refuse, &c. ; common and widely distributed throughout the 

 greater part of England ; Scotland, not common, Tweed and Solvvay districts. 



Zi. formicetoruxn, Maerk. A very small, linear species ; easily 

 distinguished from the preceding by having the elytra to a greater or 

 less degree testaceous, the colours being rather bright and usually well 

 defined ; the antennae have the third joint subglobosc, evidently shorter 

 than the second, whereas in L. linearis they are about equal ; the head
