the disk ; the anterior angles are moderately prominent and 

 acute ; the sides are distinctly margined, broadly so in front, 

 as if impressed above the anterior angles; rectilinear, except 

 near the anterior angles, where they are gently arcuate. The 

 elytra are less convex, rather more straight at the sides ; the 

 striee are scarcely so well marked ; and the punctuation of the 

 interstices is finer. The legs are very long, pitchy.

Mycteristes microphyllus^ n. sp. 



(^ . Slender. Above obscure bronzy, with dull greenish 

 reflections, and sparsely clothed with minute whity brown 

 appressed squamiform setas ; legs and under surface more 

 brilliant and redder bronzy, without green reflections, but with 

 a similar clothing of setge, which are longer and denser on the 

 thorax ; exposed outer ends of abdominal terga densely 

 clothed with whity brown setiform scales ; tarsi black. Cly- 

 peus concave, with its anterior angles pointed, produced, and 

 somewhat divergent ; its front margin armed with a short and 

 broad-stalked small subcrescentic process, which is slightly 

 transversely concave behind and correspondingly convex in 

 front. The crown of the head produced horizontally over 

 the clypeus into a short, truncated, triangular, lamellar pro- 

 cess, divided at its extremity into two rounded points by a 

 median notch. Pronotum unarmed. Mesosternal process 

 very short, porrected in front, not produced downwards beyond 

 the level of the sternum. Abdomen grooved along the middle 

 below. Fore tibijB externally tridentate ; four posterior ones 

 bidentate, as in M. rliinophyllus. 



Length from extremity of cephalic horn to end of abdomen 

 19 millims. ; breadth across bases of conjoined elytra 7'7o 

 millims. 



While I was in England on furlough in 1877-78, Mr. E. 

 W. Janson showed me an insect which I at once recognized 

 as the female ; it differs from the male in having the clypeus, 

 as in M. rliinophyllus ^ simple, but, as far as I recollect, in no 

 other point of any moment.
