(Plates XIY. & XV.*) 



In the ' Proceedings ' for 1894 (p. 609) I have given the descrip- 

 tions of many species belonging to the gronp of bladder-clawed 

 Ilalticincp., which until then were simply Catalogue names as 

 published by Clark. The number of further species which I have 

 received since enables me to publish here a considerable addition 

 to my former paper ; where Clark's names have been retained foi- the 

 same species I have stated this, but by far- the greater portion of 

 my species were not known to Clark. The genera OedionycMs and 

 Asphcera as at present understood almost rival in species the 

 Galen^cid genus Diah^otica, and it is frequently very doubtful to 

 which of the two genera a species should be referred. Von 

 Harold has tried to point out the diflerences between OedionycMs, 

 Asjyhmra, and the allied genera (Coleopterol. Hefte, xv. p. 91), and 

 lays the principal stress on the more or less elongate first joint of 

 the posterior tarsi in Asphcera in contradistinction to the corre- 

 sponding very short joint in OedionycMs, which in most cases 

 holds good, but in many instances theie are intermediate degrees 

 as well as in the more or less inflated claws, so that it is uncertain 

 to which genus these species should be referred ; these are, 

 however, rather exceptional, and v. Hai'old's definition must be 

 accepted for want of a better one. All the species described here 

 aie contained in my collection. 



HOMOPIICETA CLAVAREAUI, Sp. n. 



Black, a, fi-ontal spot and the clypeus flavous ; thorax fulvous, 

 impvmctate ; elytra neai'ly impunctate, fulvous, a broad transverse 

 band at the base and another narrower one below the middle, 

 black. 



Length 9 millim. 



Head black, very shining, with some punctures near the eyes 

 the latter widely separated, with a flavous transverse spot at the 

 intermediate space, frontal elevations nai'row, likewise flavous as 

 well as the clypeus ; antennae extending beyond the middle of the 

 elytra, black, the first joint fulvous below, third and fourth joints 

 equal ; thorax twice as broad as long, the sides feebly rounded, 

 with narrow thickened margins, the anterior angles strongly pro- 

 duced and thickened, the surface fulvous, impunctate, rather 

 convex ; scntellum black ; elytra with narrow, reflexed mai'gins, 

 microscopically finely punctured, fulvous, with a rather broad 

 basal band occupying about one-fourth of the length of the elytra, 

 its posterior edge oblique, widest at the suture, another narrower
