Dicyrhis and Thecacerus. Altes hinodosus^ represented on 

 Plate XII. fig. 2, is an ovate, convex, dark cojiper-brown 

 insect, sparsely furnished with long flying hairs on the body 

 and legs. Charto2)teryx has erect scale-like hairs, rather 

 thickly clustering at the base of the elytra, very different in 

 their character and distribution from those on Altes. 



Decialma. 



Subfamily Ctphalein^. 



Antenna? art. penultimis bre\ater obconicis. 



Tiblce obsolete calcaratse. 



Tarsi lineares, art. ult. elougato. 



Head exserted ; clypeus broad, separated from the front by 

 a straight groove. Eyes not contiguous to the prothorax, 

 })roniinent, broad, nearly entire. Antennae short, slender, the 

 last six joints thicker than the rest, third shorter than the two 

 next together, all, except the last, more or less obconic, the 

 last ovate. Mentum trapezoidal, narrow at the base. Pro- 

 thorax transverse, broadly emarginate at the apex, slightly 

 foliaceous at the sides. Elytra oblong, slightly depressed ; 

 epipleiu'ffi obliquely descending, nearly obsolete towards the 

 apex. Legs short ; femora thickened ; tibiae linear, very 

 shortly spurred ; tarsi slender, the claw-joint elongate. Pro- 

 sternum produced behind. Mesosternum with a V-shaped 

 notch. 



It is with some hesitation that I propose this as a genus 

 distinct from Olisthcena, Er.*, which is unknown to me, but 

 with which it agrees, so far as he has characterized it, with 

 the exception of the antennae : these he describes as having 

 the penultimate joints longer than they are broad, by which 

 character he differentiates it ixora Pachycoelia {= Lejjisinlus) . 

 On the contrary, in Decialma the penultimate joints are broader 

 than they are long ; and in a subfamily like the Cyphaleina?, 

 remarkable for a difference of habit without a correlative dif- 

 ference of structure, a character like the above becomes of 

 importance. 



Decialma tenuitarsis. 



D. oblonga, modice couvexa, nitida ; capitc prothoracequc nigris ; 

 clytris fuscis, vage piinctatis.

Oblong, moderately convex, shining ; head black, very 

 closely and rather finely punctured, but A^•ith few punctiu-es on 

 the clypeus ; prothorax black, minutely and sparsely punc-
