A specimen from the ma,n River belonging to Mr. Lea 

 is, I think, certainly a Timber of this genus, and I can find 

 no reason to separate xt generically from the specimen dis- 

 cussed above as beinf probably Prochelyna, unless a dissection 

 of the mouth organ oi both species should serve the purpose. 

 Even as species ^ e two are decidedly close. The specimen 

 from Swan Riv r agrees very well with the description of the 

 typical specie c f-4. obscurus, Shp.) — also from Swan River — 

 except in it elytra being wholly fuscous (the lateral margins 

 excepted) and not at the base only. It seems, however, to be 

 certainh distinct sexually from the specimen I refer to 

 Proch&yna, its antennal flabellum being much shorter, its 

 tarsi evidently shorter, its pygidium notably less vertical and 

 mum more convex, and its ventral segments distinctly longer. 

 Its most remarkable character, however, consists in the pre- 

 sence on the middle of the pronotum, a little behind the 

 front, of a small deep fovea on the level of the general sur- 

 face in its hinder part, but in its front part sinking into the 

 general surface in such fashion that its front part has a semi- 

 circular vertical wall, on either side of which there is a small 

 but distinct tubercle. As the other characters of the speci- 

 men are fairly conclusive of its being a female, and this 

 prothoracic fovea seems like a male character, I should be 

 disposed to regard it as an accidental abnormality, were it 

 not for the reference mentioned above to the presence of two 

 tubercles on the pronotum of a species which Schaufuss has 

 referred to Prochelyna. Unfortunately the Systellopides are 

 so rarely met with that I have never yet been able to examine 

 two specimens that are unquestionably the sexes of a single 

 species. It should perhaps be added that the present insect 

 and that I have discussed under Prochelyna can scarcely be 

 the sexes of a single species, on account of considerable differ- 

 ence in elytral striation — which is not likely to be of a sexual 

 character.
