314 ENTOMOLOGICAL NOTES. 



truncatus ; lateribus, lineisque quatuor disci longitudinalibus 

 perspicue elevatis : elytra valde depressa, marginibus, sutura, 

 lineisque diiabus singuli disco longitudinalis perspicue elevatis : 

 segmenta septem nuda, baud elytris tecta, medio depressa, lateribus 

 elevatis, versus telum magnitudine pedetentim decrescentia ; telo 

 elongato angusto. 



Pseu. sulcatus. Niger, ore antennis pedibusque fuscis. 



Head long, narrow, rounded before, black, vi^ith tbe mouth brown ; 

 crown of the head very much depressed, with an elevated line 

 passing along each side above the eyes, and a third less elevated, 

 distinct and regular, passing between these down the centre : 

 antennae brown, moniliform, composed of eleven joints, of which 

 the apical is somewhat conical ; the folloAving are rather more 

 broad than long, and very gradually decrease in size towards the 

 head : maxillary feelers, with the apical joint long, pointed, and 

 very slender ; the next incrassated, four times the size of the 

 apical : the disk of the prothorax is somewhat circular, but 

 evidently truncate anteriorly, and slightly so posteriorly ; it is 

 much wider than the head, and very flat ; it has the lateral edges 

 and four perfectly straight longitudinal lines on the disk very 

 conspicuously elevated, thus producing five distinct longitudinal 

 indentations or furrows : the elytra are rather wider than the 

 prothorax, very flat, with their margins, suture, and two longitu- 

 dinal lines on each, conspicuously elevated ; the lines are not 

 perfectly straight, but, as they recede from the base of the elytra 

 exteriorly, incline towards the suture : there are seven segments 

 entirely uncovered by the elytra ; these are much depressed in 

 the middle and elevated at the sides, and gradually decrease in 

 size to the last, which is very long and narrow : the prothorax, 

 elytra, and uncovered segments, are dull black : the legs are 

 brown. (Length ]| line.) 



This singular insect was taken, by Mr. Walker, in the Isle of 

 Wight, in the month of September. I regret not being able to 

 furnish more complete characters from its mouth, but, as it is 

 unique and exceedingly valuable, it would have been too great 

 a risk to have attempted dissection. Its appearance is precisely 

 that of a Mlcropeplus , to which genus it is evidently related, 

 although presenting in so marked a manner the characters of 

 Staphylmites. I hope the scientific reader will pardon the 

 repetition of the supposed generic characters in English ; for.
