664 Descriptive List of 



tral fovea, and completely divides the vertical part of the head, which, thus 

 separated, consists of two highly raised, glabrous, reniform masses ; the eyes 

 are distant, distinct, lateral, and somewhat triangular, towards the hack of 

 the head they are rather acute, and altogether have the appearance of eyes 

 partially closed ; under a glass of high power, they exhibit very clearly the 

 usual hexagonally facetted appearance : the prothorax is narrower ante^. 

 riorly, somewhat convex laterally, and quadrate posteriorly, its lateral mar- 

 gins have a distinct ridge, and its dorsal surface has three deep longitudi- 

 nal furrows, neither of which quite reaches the anterior margin, and the 

 central one is slightly separated from the posterior margin, but the line of 

 separation is very attenuated and obscure, the lateral furrows are posterior,. 

 ly dilated, and reach the extreme margin ; the prothorax throughout is ir- 

 regularly but deeply punctured : each of the elytra has seven deep strice, 

 five of them dorsal and two lateral, these strice are regularly punctured, the 

 interstices between them smooth: the protibice have a sharp tooth before 

 their apex, curved forwards, and two sharp teeth at the apex, curved down- 

 wards. 



Inhabits Java. The only specimen I have seen is in the 

 cabinet of the Entomological Club.

Colour shining pitchy black; the head is nearly triangular, the posterior 

 angles being rounded, the crown is divided by a deep impression, which 

 commences in a narrow posterior furrow, expands to a fovea between two 

 large raised convex glabrous masses, then divides anteriorly, reaches the 

 base of each antenna, and here incloses an elongate glabrous space, and fi- 

 nally unites and ceases in a depressed space adjoining the clypeus ; the eyes 

 are small, oval, lateral, and situate near the base of the antenna, and exhi- 

 bit the usual hexagonal facets ; the prothorax has the anterior and posterior 

 margins truncate, and of nearly equal diameter , the posterior angles are 

 quadrate, the lateral margins convex, and furnished with a distinct margin- 

 al ridge ; its dorsal surface has three deep longitudinal furrows, none of 

 which reach the anterior, but all of them the posterior margin ; they are of 

 equal length, and are alike dilated posteriorly. Each of the elytra has se- 

 ven distinct punctate strice, five of them dorsal, two lateral : the protibice 

 have "the inner edge produced at the tip, both above and below, into a bent 

 obtuse spine, below each of which there is a much smaller spine, and the 

 surface of which, between the spines, appears, both above and below, to be 

 emarginate and ciliated."* 



Inhabits the United States of North America, and, if Mr. 

 Westwood' s informant prove correct, the continent of Europe 

 also ; but 1 am much inclined to doubt the latter habitat. 



In the cabinet of Dr. Harris, Boston, U- S., who took it in 

 Alabama ; also in the cabinets of the Rev. F. W. Hope, and 

 Mr. Westwood, to whom I am indebted for the loan of specie 

 mens for description.
