CYATHODEEA — ANOPLISCHITJS. 305 



I have seen five ( <? ) specimens of this species, two of which are from Central 



America. The males have a smooth, glabrous, oblong space on the fifth ventral 



segment near the apex. The elytra are mucronate at the sutural angle, a character 

 not mentioned by Candeze. 



ANOPLISCHIUS. 



Anoplischius, Candeze, Monogr. Elat. ii. p. 49 (1859). 



Of the fifty-five described species of Anoplischius, all but one are from Central or 

 South America or the Antilles. It differs from Ischiodontus in having the coxal 

 plates obliquely narrowing outwards from the dilated inner part, and not triangularly 

 dilated towards the middle ; many of the species, however, have the coxal plates feebly 

 subangularly dilated at or before the middle, and these forms are more or less inter- 

 mediate. In all the species of Anoplischius I have examined the prosternal process 

 has an angular tooth or prominence before the apex. Twenty-three species are here 

 enumerated from within our limits, eighteen of which are described as new. 



a. Antennas with the third joint small, very much shorter than the fourth . . Species 1-5. 



b. Antennse with the third and^ fourth joints subequal. 

 a'. The antennal joints densely punctured throughout. 



a". Prosternal sutures not or scarcely grooved in front ; elytra greenish 

 or with a greenish lustre ; antennse exceedingly elongate in the 



male Species 6, 7. 



b". Prosternal sutures more or less grooved in front. 



a'". Prothorax and elytra concolorous — ferruginous, piceous, or brown. 

 a 4 . Prothorax rounded at the sides anteriorly ; the hind angles not 

 or scarcely divergent. 



a 5 . Prothorax closely and coarsely punctured Species 8. 



b\ Prothorax finely and more sparsely punctured Species 9, 10. 



b*. Prothorax narrowing from the base ; the hind angles divergent. 

 C s . Elytra moderately elongate. 



a 6 . Prothorax closely punctured Species 11. 



b e . Prothorax sparsely punctured Species 12, 13. 



d". Elytra very elongate Species 14. 



b'". Prothorax partly rufous or flavous. 



c\ Elytral pubescence uniform in colour Species 15, 16. 



d\ Elytral pubescence paler along the suture and margins . . . Species 17, 18. 



c'". Prothorax rufous or yellow Species 19, 20. 



b'. The antennal joints, or at least the basal ones (1 and 2 excepted), with 

 a smooth line or carina along the middle above and beneath. 

 c". Elytra narrower than the prothorax, the humeri excavate; hind 

 angles of the prothorax incurved, very sharply carinatej meso- 

 sternum raised at the sides ; colour black or piceous ..... Species 21.
