C. hifasc'iata, however, has a blue abdomen of the same 

 colour as the rest of the body. Nevertlieless I think 

 C. viayeti is distinct from C. hifasc'iata on account of the 

 very narrow posterior fascia of the elytra. 



Conognatha apicalis^ sp. n. 



Brassy black, shining; thorax strongly impressed on the 

 disk, witli a deep fovea above each posterior angle. Elytra 

 yellow with black apical markings. The thorax is delicately 

 and not closely punctured ; much narrowed in front, some- 

 what abruptly enlarged at tlie middle, and then continuing 

 to become wider to the posterior angles. The discal im- 

 pression is very large and is continued to the front margin 

 by a channel ; the eflFect of this is to leave two slight but 

 distinct tubercles in front of the middle. The scutellum is 

 rather small, rounded posteriorly. The elytra are exactly 

 the width of the base of the thorax, parallel for two-thirds 

 their length, then narrowed to the apex. The striae are 

 rather tinely punctured, moderately impressed (except near 

 the scutellum), the interstices slightly convex. At a little 

 distance from apex there is an irregular transverse oval black 

 spot, and a small spot near the margin. Behind this there 

 is a fascia which does not quite reach the margin, much 

 narrowed at the suture, angulated in front. The apex is 

 black, and is united to the fascia by the black suture. The 

 apical margins are acutely dentate. The usual apical spines 

 are strong, not very widely separated, the outer one the 

 larger. Abdomen obscure red, with blue reflections. ? .

The specimen described is from the same locality as 

 C. posticabs, Saund., and was collected with it, and was 

 believed to he that species until the Museum received the 

 type from Fry's collection. It differs from that species in 

 having the thorax very deeply impressed on the disk, the 

 elytra have no humeral spot, the ajiical spots are slightly 

 different (in post icalis the subapical fascia reaches the margin, 

 but does 7iot reach the suture and is vot united witii the 

 black apex), the apical s|)ines are larger, the stria? are more 

 impressed, and, lastly, the abdomen is entirely red, whereas in 

 posticahs only tiie apical three segments are yellow. 



C(.n"cinatlia nigro-purpurea , ?p. n. 



Daik purple, appearing almost black in some lights. 

 Thorax very obliquely narrowed anteriorly, punctuation very
