however, are quite obsolete ; interstices slightly convex near 

 the suture, the third tripunctate, posterior plica only moderately 

 developed. There are two setigerous punctures on each sido 

 of the middle, at the apex, o£ the terminal segment. 



With the exception of 0. latipennis this is the most dis- 

 tinctly sculptured of all the larger members of the genus ; 

 that species, however, may be recognized at once by the 

 acutely projecting angles and punctate base of the thorax.

A single male, one of Commander J. J. Walker's numerous 

 discoveries whilst serving on board If. M.S. ' Ringarooma.' 



A second specimen has been labelled 0. ovtnotatn.<, having 

 a large well-defined oval impression on the middle of the 

 thorax, some fine transverse rugae near the base, and more 

 shallow and less laterally expanded basal fovese, &c. 



Group Anisodactylidae. 



AUocinopus ocularius, sp. n. 



Elongate, slightly convex, nitid, black ; mandibles piceo- 

 rufous ; the legs, antennae, and palpi testaceous ; the elytral 

 margins, near apices, fusco-testaceous. 



Head (including the large rotundate and prominent eyes) 

 about as broad as the widest part of thorax, nearly as long as 

 that is, much contracted behind ; it is smooth, with setigerous 

 punctures as in A. sculpticollis, but with six instead of four 

 on the labium, the inter-antennal impressions not extending 

 backwards as far as the middle of the eyes. Thorax one- 

 fourth broader than long, widest just before the middle, 

 moderately rounded towards the front, considerably sinuously 

 narrowed backwards, posterior angles rectangular, but not 

 acute ; base widely, but only slightly medially emarginate, 

 apex incurved, lateral margins well developed ; dorsal groove 

 well marked, but not attaining the base or apex ; basal fossse 

 of moderate size, from the inner side of each of these to the 

 middle of each side the surface appears flattened or depressed 

 and, as well as the middle, more or less finely punctate and 

 rugose. Elytra oblong, rather wider than thorax at base, a 

 good deal narrowed and slightly sinuate behind, apices 

 individually rounded and slightly dehiscent at the suture ; 

 with regular, well-marked, impunctate strise, between the 

 sutural and second stria? there is a short oblique basal one. 

 hus forming an additional interstice there, the marginal 

 punctures become irregular behind.
