108i COLEOPTEKA 



Coxelus. 



1931. C. rufus, ii-'i- Suhopaquc, dark-red, clothed with pale- 

 yellow seta?. Head indistinctly impressed along each side, granu- 

 late. Thorax widest near the front, gradually narrowed towards 

 the base, its lateral margins closely serrate or denticulate, more 

 widely explauate in front of the middle than behind ; its surface 

 granulate, with a broad shallow impression before the middle, two 

 smaller ones behind that, and with a narrow depression along the 

 base. Elytra with two large but not deep depressions nearly as far 

 back as the hind thighs, scutellar region hot depressed ; with rows 

 of small granules or punctures, from these the sette arise. Legs 

 with slender yellow^ setae. 



C. clialmeri is a quite different insect. C. duhiiis makes the 

 nearest approach to this species, from which, how"ever, it differs 

 in the more widely explanate sides of the thorax, causing the 

 front part to appear broader ; the sculpture, too, is different. The 

 elytral sculpture is very dil!icult to determine, for when examined in 

 one w"ay it seems to consist of small shining granules, whilst when 

 viewed in other directions these rows of granules appear as if trans- 

 formed into punctures. 



Length, 1^ lines ; breadth, f line. 



Taieri, Otago. Mr. S. W. Fulton ; a single individual. 



1932. C. posticalis, i^-s. O^ja^"^'' ^'^^^^''^^^taneous, legs paler ; 

 the antennge, save the reddish two basal joints, nigro-fuscous ; the 

 setae yellow, very coarse and squamiform, somewhat unevenly dis- 

 tributed on the elytra, more slender on the head and thorax, quite 

 fine and short on the legs. 



Head roughly sculptured ; eyes prominent. Aiitennce short, 

 basal joint almost invisible above ; second stout, twice as thick as 

 and distinctly longer than the third ; 4-8 small, about equal ; ninth 

 a little larger than the preceding one ; club broad, biarticulate. 

 Thorax slightly broader than long, widest near the front, gradually 

 narrow^ed towards the base, the marginal channels distinct ; its 

 sculpture granular, with an elongate dorsal depression, and a less 

 distinct one nearer each side. Elj/tra without depressions, ob- 

 liquely narrowed and subacuminate apically ; they are apparently 

 striate-punctate, but when examined from behind the sculpture 

 seems to consist of series of granules. The legs and tarsi rather 

 stout. 



A rather small species, which may be easily identified by the 

 peculiar form of the posterior portion of the elytra, and the unusually 

 dark antennae.

Moeraki. One example, sent by Mr. Sandager. 



1933. C. OVicollis, "•*• Siihopaquc, obscure rufo-fuscous, 

 legs and antenucC sordid-testaceous or slightly fulvescent, club infus- 

 cate ; it is clothed with short, coarse, pallid, scale-like setae, the 

 tibiaB with vellow hair-like setae.
