3. L« linearis jravh. 



(iravh. Micr. 43; Kraatz Ins. D. II, 649; Thorns. Skand. Col. II, 

 193; Muls. at Fey Bre'vip. 1877, 110. - sulcifrons Steph. 111. Brit. V, 

 260. - batychrus var. linearis Janglb. Kaf. K. II, 487). 



I\iuch like batychrus , of which it is occasionally treated as a vari- 

 ety. It differs from batychrus by the following characteristics: 



It is ordinarily somewhat smaller and nariov.er, also of darker col- 

 or; elytra most often entirely black, rarely brownish at tip; the head 

 a little less, and the sides less densely punctate, and in each of the 

 pronotal dorsal rows fewer punctures are counted^ only about 8-10; the 

 surface of head and pronotum somewhat more distinctly trandversally 

 aciculated. L. 4. mm. 



Like the preceding species in woods and gardens at rotting plants, 

 in compost and at hothouse boxes, and not rare in this country, also 

 found in alluvium. Distributed in most of the continents like the pre- 

 ceding species.

4, L. formicetorum Mark. 



(Mark. ierm. Ztschr. Ill, 216; Kraatz Ins. D. II. 650; Thorns. Skand. 

 Col. II, 193; Muls. et Fey Br^vip. 1877, 113; JJanglb, Kaf. M. II, 488). 



Very fine and narrow, considerably smaller, especially narrower than 



linearis , and of lighter color than this, with which it in regard to the 



number of punctures in pronotal rows, and punctation of elytra etc. almost 



entirely corresponds. 



Black or pitch-black, strongly glistening, elytra brownish, posteri- 

 orly brownish-yellow, these and abdomen very sparsely and finely haired; 

 tip of abdomen often brownish; antennae, mouth-parts, and legs yellowish- 

 red.
