Neio 8]pecies of Heteromera. 265 



on each cheek enormously developed, and nearly meet- 

 ing in the centre of the head beneath. Prothorax but 

 little convex, minutely and sparingly punctate, * a ti'ans- 

 verse impression on each side the median line near the 

 base ; strongly bisinuate in front, with the fore-angles 

 prominent but rounded ; sides moderately rounded, 

 suddenly and obliquely contracted from beyond the 

 middle to the posterior angles, which are small and 

 pointed ; sinuous at the base, which, with the sides, are 

 margined, the latter reflexed, and decidedly crenulate. 

 Scutellum angulate behind. Elytra a little broader than 

 the base of the thorax ; gradually widening to beyond 

 the middle, then strongly contracted and sinuous to the 

 apex ; declivous behind, very thickly margined at the 

 base ; shoulders depressed, the humeral angles rather 

 strongly in relief ; alveolate, more decided so on the sides 

 and on the middle, with three round punctures ranged on 

 each side the scutellum. Prosternal process strongly bisul- 

 cate, obtusely rounded behind ; the intercoxal wide, and 

 broadly rounded at the apex. Legs rather long and 

 slender; all the tibiae curved, the fore tibite as strongly 

 so as in some species of Nyctohates. Body beneath, legs, 

 etc., shining black.

Dedicated to M. Henri Deyrolle, from whom I received 

 the species. 



Sub.-fam. TENEBRIONIN^. 



Gen. Dechius. 

 Pascoe, Journ. of Entom. ii. 455. 



The author of this genus gives as characters " lahro 

 ohtecto," and " maxillce loho interno mutico ; " for the 

 first of these, I cannot see that the labrum is more 

 hidden than in the ma-jority of the species of Tenehrio ; 

 and for the second, there certainly does exist a small 

 terminal claw, or hook, to the inner lobe of the maxillae. 

 But the chief distinguishing character of the genus 

 appears to have been overlooked, namely, the epipleural 

 fold of the elytra incomplete behind ; in this respect assi- 

 milating it to the genus Bius. 



* Uuder the microscope, the whole siirface of the head and prothorax 

 appears veiy finely and minutely reticulate, and thickly sprinkled with 

 minute polished granules.
