148 Dr. Sharp's Revision of the 



E. monticola, Th. Ofv. Vet. Ac. Forli. 1852, p. 143;

 Th. Sk. Col. iii. 43. 



Antennae black, rather short and stout, thickened to- 

 wards the apex, joints two and three of nearly equal 

 length, four to ten each one broader than the preceding, 

 from the fifth onwards distinctly transverse ; eleventh 

 joint pointed, rather short, half as long again as the tenth. 

 The head is rather broad, narrower than the thorax, mo- 

 derately shining, finely and sparingly punctured ; in the 

 male with a broad impression, in the female with a chan- 

 nel. Thorax narrower than the elytra, transversely con- 

 vex, more than a third broader than long ; the sides 

 gently rounded, scarcely narrowed behind, finely and not 

 densely punctured ; in the male with a broad impression 

 in front of the base in the middle, in the female with an 

 indistinct one ; sometimes also with an obsolete longitu- 

 dinal channel. The elytra are one-third longer than the 

 thorax, of a brownish colour, moderately shining, their 

 sculpture and pubescence fine. The abdomen is shining 

 black, at the base very sparingly punctured, at the apex 

 impunctate. The legs are pitchy-yellow. 



In the male, the head and thorax are more impressed 

 than in the female, the seventh dorsal segment of the ab- 

 domen has the apex in the middle deeply triangularly 

 emarginate, the sides have a very distinct raised margin, 

 the apical margin is also raised, but less distinctly than 

 the sides, and is furnished with four raised longitudinal 

 folds ; of these, the two inner are parallel to one an- 

 other, the two outer converging towards the apex. 



In the female, the posterior margin of the seventh dor- 

 sal segment is a little emarginate in the middle. 



Rare. I have found it at Croydon, on Purley Downs, 

 and near Thornhill in Dumfries-shire. 



The male appears to be quite as common as the female, 

 and the remarkable structure of the seventh segment of 

 its abdomen should prevent its being mistaken for any 

 other species. 



Ohs. — Two specimens ( ^ and $ ) of If. monticola sent 

 by Kraatz to the British Museum agree with my spe- 

 cimens.
