turned stron<^ly upwards in consequence of ;i deep depression ex- 

 tending all across the pronotuin, and (2) the front of the head eon- 

 cave and canaliculate. 



T. craioshnyi belongs to a group of three species, distinguished 

 by the obsolete basal margin of the pronotum. The three species 

 are : T. gracilicorne, Heitter, T. gnhrieli, Weise, and T. crawshayi, sp. 

 n. T. gracilicorne is an inhabit'int of Eastern Siberia; it is extremely 

 like T. crawshayi, but the thorax has shorter and less densely punctured, 

 and the middle part of the head is longitudinally concave. I am in- 

 debted to Herr Reitter for communicating seven individuals of his 

 species ; they are all 1 have seen, the insect being represented 

 neither in my own collection nor in that of the British Museum. 

 The specimens sent by Herr E-eitter are unfortunately all females, 

 but I have no doubt of the distinctness of these two forms. 



T. crawshayi is really nearer to T. gabrie.li, though the two look 

 very different on account of the bright red legs of the second of these 

 species. This being a variable character in T. luridum I should 

 have supposed T. crawshayi and gahrieli to be mere forms of one 

 species, were it not that the splendid series of crawshayi obtained by 

 Mr. Crawshay shows that the colour of the legs is quite constant. 

 In addition to this the punctuation of the thorax is rather coarser in 

 T. gahrieli. and the thorax is a little longer and narrower. The male 

 genitalia offer both in the parameres and aodeagus some distinctive 

 characters in the species of Tefropium, but in consequence of in- 

 sufficient material I am not able to fully appreciate these differences 

 in the case of T. gahrieli, and I must leave this point for subsequent 

 investigation.

The male, compared with the same sex of T. crawshayi, is a little 

 more robust and convex, with thicker legs and antennae, has the 

 vertex canaliculate and the thorax less densely and less uniformly 

 punctate and rather shorter in proportion to its width, and the colour 

 is different. 



The female of T. parcum differs from the male by its more slender 

 legs and antennae, and by a more punctate thorax, with only very small 

 and vague smooth areas on the disc. The female differs from the
