ADEPHAGA.

Similar in every respect to K rhombifer, the thorax, as in that species, being b 









1 sides nearly straight from the angles to near the apex, then broadly rounded to 

 neck, and the elytral interstices flattened towards the apex, and the black X mark

being 



supplemented by posterio 



less

X mark a rhomboidal pale spot; but the thorax lacks the two dorsal black

3. Nemotarsus fallax.

I refer doubtfully to this species specimens taken by Mr. Champion. In the form 

 of the thorax, " de fort peu plus large a sa base que la tete avec les yeux," they agree 

 fairly well with Chaudoir's description, N. rhombifer and limbicollis having a much 

 wider thorax ; but they differ in the markings of the elytra both from N. fallax as 

 described and amongst themselves, the pattern being in one example nearly as in 

 N. rhombifer, and in the other limited to two completed basal rings.

Subfam. MASOBEINJS. 





- 



A subfamily equivalent to the Masoreides of Chaudoir's 'Etude Monographique/ 

 which group, although differing widely in facies from the Tetragonoderinse, with which 

 it agrees in the long tibial spurs, the author considered to be linked to that subfamily 





■ 















by the genera Ophryognatliiis (unknown to me) and Cyclosomus. If similar connecting 

 links should be discovered between all these small subfamilies of Truncatipennes having 

 long hind tibial spurs (dissimilar as they are in other respects), they would doubtless be 

 considered as constituting but one subfamily.
