and the long first joint of its autennal club assigns it to the section 

 with /'linthus. 



I have seen but three examples of the insect, all of which had 

 more or less incrusted integuments. My own specimen was particularly 

 " dirty," so I partially cleansed it before taking the photograph. On 

 examining under a ^i; iii<^"h objective the "dirt" so obtained, it was 

 quite certain that the matter was not of an earthy character. Probably 

 the incrustation is a natural exudation? Moreover, the "pubescence" 

 in the cleansed individual presented the appearance of short, bristly 

 hairs, curved for nearly their entire length, thereby causing their 

 distal ends closely to approach the integument ; whilst on the antero- 

 lateral part of the thorax the hairs were unciform. May it not be 

 that the function of these hairs is to help retain the exudation ? The 

 sculpture of the thorax consists of deep, round punctures, varying in 

 size and irregular in ari'angement, with the interspaces very finely 

 punctured ; the punctures in the elytral striae are bold and saucer-like. 

 The words in the original description, " thorace ad apicem valde con- 

 stricto," seem scarcely apt, as the front of the disk of the thorax in 

 my example is not at all constricted, whilst in Mr. Champion's two 

 specimens a constriction is hardly traceable. In all three of them the 

 sides of the thorax for about the anterior fourth are strongly and 

 suddenly narrowed in such a way that suggests the effect that would 

 be produced by compression by square-jawed forceps, or the scoop-out 

 of an angular gouge, rather than that which would result from con- 

 striction. The three examples are not, however, absolutely identical 

 in appearance in this respect, and they also vary considerably in degree 

 in the distinctness of the median carina, so that some allowance must 

 apparently be made for variation in the subordinate characters of the 

 species. 



I regret being able to record the capture of one example only, 

 which I obtained so long ago as July, 1893, near the mouth of the 

 River Yealm, Plymouth. It has been resting since then with my 

 specimens of Orthochaetes setiger, till I recently had occasion to 

 examine the whole of them.
