COLEOPTERA 375 



Readily recognisable by the coarse punctuation of the intensely black thorax, 

 which is nevertheless shining, by the divided coloration of the elytra, and the brightly 

 flavescent femora. In these characters it is approached by some of the varieties of 

 E. variaiis, but that species has a marked dilatation of the tarsi, which is not the case 

 in E. divkjts, moreover the pallid colour of the base of the elytra is remarkably pale in 

 E. divisiis. The shape is rather peculiar, the insect being somewhat broad in the 

 middle and much narrowed behind, so that the interstices of the elytra are broad in 

 front but at the tip are very narrow : the actual tips are distinctl\- spinose. There is a 

 slight dilatation of the base of the anterior tarsi, but not of the other two pairs. 



Hah. Oahu, Honolulu, 2000 ft. in iSq6 (Perkins). 



Certain of the specimens are numbered 210, which refers to Kona in Hawaii. 

 I feel convinced that this is erroneous, and that the species is really confined to the 

 mountains of Oahu. Cf remark under E. obsciiriis. Mr Perkins remembers finding 

 this insect in Oahu.

We have a very large series of about 300 specimens of this species, which is very 

 variable. In colour it pas.ses from entirely black to light brown. The thorax is a good 

 deal narrowed in front, the sides having usually a slightly concave curve. There is 

 much pubescence on the thorax, usually of a pallid colour. The thorax is rather 

 closely punctate but shining. The elytra are distinctly dehiscent at the tips, and 

 minutely spinose. The length varies from 7^ — w^ mm. The male has the antennae 

 rather longer than the female, about 2 joints extending beyond the hind angles of the 

 thorax, while in the female they extend scarcely at all beyond the hind angle ; the length 

 in a moderate sized f is about \\ mm. There is a very slight development of the fine 

 pubescence on the under surface of the basal three joints of the feet, and an extremely 

 slight incrassation of these joints ; the 4th joint of the hind foot is 2 or 3 times as long 

 as it is broad.

Augustus, nigerrimus, nitidus, parce pubescens, pedibus flavis, tarsis tibiisque

Narrower than E. konae, with the thorax more sparingly punctate, and the 

 pubescence of the upper surface much less developed. The pubescence is black, so
