Species of Histeridge. 4 23 



Coryphaeus pilosus^ sp. n. 



Breviter ovatus, parum convexus, viricli-cyancus, pilosus, supra 

 punctulatus ; fronte in medio canaliciilata ; prouoto convexo ; 

 elytris striis T'-S'" subintegris ; prostei'iio bistriato ; mesosteruo 

 immarginato, antice subacute producto, 



L. 61 mill. 



Shortly oval, little convex, pilose, entirely and rather 

 densely punctulate above, greenish blue, metallic ; the fore- 

 head witli a shallow median channel, which divides in front 

 and forms a rather broad hamate impression along the ante- 

 rior edge, the lateral stria over tlie eyes is very obscurely 

 marked, if not obsolete; the thorax — lateral margin very 

 narrow and punctulate, and within it a lateral band of large 

 grater-Hke punctures (Marseul called similar punctures in 

 C. Wallacei " rapeux "), the band is narrower than in Mar- 

 seul's species and inclined to be broken in the middle, and is 

 widest behind the anterior angle, in front of the scutellum 

 there is a minute shining boss ; the scutellum is very small, 

 triangular, and quite smooth ; the elytra — striee, subhumeral 

 arched and not well-marked, humeral evanescent towards 

 the apex, dorsal 1-3 rather wide but sliallow and termi- 

 nating apically in punctulate impressions, the dorsal disk is 

 uneven and is free from the brown pilosity ; the propygidium 

 and pygidium are much less cyaneous than the elytra, but are 

 similarly punctulate ; the prosternum bistriate, striee joining 

 anteriorly, keel finely punctulate ; the mesosternum rather 

 acutely produced in front, immarginate, punctulate like the 

 keel j the femora greenish, tibias brownish and pilose, formed 

 as in C. Wallacei, the tarsal grooves of the anterior tibiae 

 being shallow, and the outer edges of the tibise are straight. 



Hah. Tenimber [Doherty). 



This species differs chiefly from G. Wallacei, Mars., in 

 being pilose and wholly punctulate above, with thorax con- 

 vex at the sides as well as on the disk, and by the meta- 

 sternum being somewhat acutely produced anteriorly. Mar- 

 seul published the genus Coryphceus in 1864, but in 1869 he 

 placed it in a supplementary Catalogue (Ann. Soc. Ent. 

 Belgique, xiii. p. 133) as a subgenus of Pachycrcerus. It is 

 entitled to full generic rank, and I think the position assigned 

 to it in this paper better than placing it near Pachycrcerus. 



SynocUtus Schmidti, sp. n.

 iutegris punctiformibus, interstitiis Isevibus ; prosterno bioarinato,
