strongly fringed, inner lobe narrow, elongate, and unarmed ; 

 the palpi with the last joint narrowly securiform. Prothorax 

 small, transverse, a little expanded at the sides, the pronotum 

 separated from the flanks by a well-marked carina. Elytra 

 very ample, oblong, convex, slightly incurved at the sides ; 

 epipleurse entire and channelled nearly throughout. Legs 

 slender ; femora rather short, fusiform ; tibise thicker below, 

 manifestly spurred, the posterior longest ; tarsi slender, as long 

 as or longer than their tibiae, the anterior as long as the inter- 

 mediate and posterior, thickly pilose beneath. Presternum 

 elevated, a little produced behind ; mesosternum V-shaped. 

 Intercoxal process triangular. 



The state of the subfamily to which this genus belongs is 

 at present one of the most unsatisfactory of all the Heteromera. 

 The typical genus Strongylium* ', which has been recently 

 elaborately monographed by M. Maklinf, contains 266 species, 

 exclusive of those in English collections ; and, as may be 

 supposed, there is no more definite generic idea to be obtained 

 from such a number than there would be from the same num- 

 ber in any one of the so-called genera of the Linnean epoch. 

 Putting, therefore, Strongylium aside as merely a designation 

 for a collective number of discrepant forms, the genus before 

 us may be at once distinguished from all others of the sub- 

 family by the great length of the anterior tarsi, which if any- 

 thing rather exceed the rest in that respect. The prothorax 

 is also very different from anything that obtains in the other 

 genera of this group, except Dicyrtus and Psydus. I am un- 

 able to give the sex of my specimen, or to say if there are any 

 sexual differences. Dr. Howitt has not given me its exact 

 habitat.

Copper-brown, glossy ; head distinctly and closely punc- 

 tured ; clypeus imperfectly separated from the front ; antennae 

 extending a little beyond the prothorax, joints five to ten gra- 

 dually thicker and shorter, of a paler colour, and pubescent ; 

 prothorax finely punctured, almost twice as broad as long, 

 rounded at the sides anteriorly, a little incurved behind the 

 middle, with the posterior angles acuminate, the apex slightly 

 emarginate, the base with a broad middle lobe ; scutellnm 

 curvilinearly triangular, the middle pilose ; elytra much broader 

 than the prothorax, and about five times its length, oblong, a
