new Species of Histeridse. 395 



lateral stria short and obscure, beginning before the coxfe only 

 and ending before the transverse suture, which is well marked ; 

 the anterior lobe is short and transverse ; mesosternum 

 bisinuate anteriorly and margined with a stria ; propygidium 

 and pygidium rather densely punctured. 



Eretmotus has two claws on each tarsus. 



Hah. Saida, Algeria (^Baron Bonnaire). 



Trihallus corylophioidesj sp. n. 



Circularis, supra convexus, picous, nitidus ; prouoto elytrisque late- 



ralibus striatis ; prosteruo bistriato ; antenuis pedibusque rufis. 

 L. 1| mill. 



Circular in outline, convex above, piceous, shining ; fore- 

 head slightly convex, clypeus short and obtuse ; thorax, lateral 

 stria well marked, ceasing at the anterior angle, and sinuous 

 in the middle ; elytra with a stria similar to that of the thorax 

 at the sides, no dorsal stria ; the whole of the upper surface 

 appears finely punctulate under strong microscopic power, but 

 there is no other sculpture ; prosternum broad, with a fine 

 and short stria on each side near the coxse ; before the ante- 

 rior lobe is a feeble but distinct transverse ridge, and the edge of 

 the lobe is narrowly reflexed ; the meso- and metasternum and 

 the first segment of the abdomen are without stride ; the meso- 

 sternum is anteriorly nearly straight ; legs reddish, tibise a 

 little dilated before the tarsi, edges without spines. 



This species in the almost total absence of sculpture 

 resembles an Idolia. 



Hah. Sumatra. 



Saprinus Jlavipenms, P^ringuey . 



The type of this has been kindly sent to me by Mr. L. 

 Peringuey, and I find it does not differ from cruciatus^ F. 

 It is a European species, which occurs also as far south as 

 the Transvaal. 



Sapeinodes, gen. nov. 



I propose this genus to receive a curious species from 

 Queensland ; it differs from Sajn^inus in having slender falci- 

 form anterior tibise, narrowed at either end, and in having 

 two thirds of their length grooved for the reception of the 

 tarsi. The anterior tibia also is carried on beyond the point 

 where the tarsi are inserted, and terminates in a very con- 

 spicuous hook. The body is not very convex and the legs 

 are longer than in Saprinus, while the prostcrnal cavities in
