transverse in the female, the sides very sh'ghtly rounded at the 

 middle, the anterior angles ohlique, forming a tooth at some 

 distance from the middle, the surface finely granulate and closely 

 and finely punctured ; elytra widened towards the middle, each 

 apex rounded, the surface slightly more strongly punctured than 

 the thorax, the punctures closely arranged in irregular rows : 

 posterior tibisB distinctly toothed at their upper margins, their 

 metatarsus shorter than half the length of the tibiae, posterior 

 portion of the hind femora black.

This Longitarsus does not differ in any striking way from many 

 of its European congeners in general appearance and sculpture ; 

 the absence of wings, the uniformly coloured antennae, and the 

 partly black posterior femora will, however, help in its recognition. 

 The posterior tibiae have a distinct and rather robust spine. 



LONGITAESUS BIAlfGIJlATUS, n. Sp. 



Winged, piceous below, above obscure fulvous, antennae and 

 legs flavous ; sides of thorax biaugulate, surface closely punctured ; 

 elytra closely, distinctly, and semiregularly punctured. 



Length f-1 line. 



Head obscure piceous or fulvous, impunctate, opaque, frontal 

 tubercles absent, carina acute and sharply defined, forming a sharp 

 ridge at the middle ; antennae two-thirds the length of the body, 

 flavous, the first joint long and slender, the second scarcely shorter 

 than the third joint, the following more elongate ; thorax one-half 

 broader than long, the anterior angles strongly oblique, form- 

 ing a thickened angle near the middle, and followed by a semi- 

 distinct tooth below the latter, the surface finely and closely 

 impressed with somewhat elongate punctures, the interstices 

 minutely granulate, obscure fulvous, opaque ; elytra more strongly 

 punctured than the thorax, the punctures arranged in closely 

 approached rather regular rows : the underside and the posterior 

 femora more or less piceous ; rest of the legs flavous, the meta- 

 tarsus of the posterior legs half the length of the tibiae.

A species of more dusky fulvous colour, which may be known 

 by the acutely raised carina of the head and the obsolete second 

 angle at the sides of the thorax, more distinct in some specimens 

 than in others. 



Sereaphtjia, n. gen. 



Body ovate, apterous ; antennae filiform, frontal elevations 

 strongly raised ; thorax subquadrate, without depressions ; elytra 

 punctate-striate ; legs robust, the posterior femora very strongly 

 dilated, their tibiae widened at the apex, the latter mucronate and 

 furnished with a long serrate prolongation scarcely shorter than 

 the tibia itself ; tarsi inserted above the apex of the tibia) ; the
