the anterior angles rounded. Elytra long, broad, subparallel anteriorly, some- 

 what acuminate at the tip, sharply margined, with just an indication of faint 

 costae and a sutural groove in certain lights. Posterior coxal plates angular. 

 Posterior legs comparatively short, the femora broad, the tibiae sharply 

 carinate, moderately widened, the upper spur much shorter than the first 

 tarsal joint. 



Length 5|, breadth 85 mm. 



Rah. Guiana, Cayenne [type] ; Beazil, Kio de Janeiro {Fry). 



The above description is taken from a fully mature ? in good con- 

 dition, from the Fry collection. This example agrees so nearly with 

 Guerin's brief diagnosis of S. cayennensis, except in its slightly larger 

 size (Guerin gives, length 4 J, breadth 2| mm.) and darker colour, that 

 it can be provisionally refen-ed to that species, which is said by him to be 

 extremely like Selodes livida. The resemblance to this genus, or rather 

 to Microcara, under which livida is now placed, is certainh' very 

 striking, as is the case in >S'. cosfulatiis Waterh., from Penang, 



6. — Scirtes Jutens, n. sp. 



5 . Oblong, shining, closely flavo-pubescent ; luteous, the suture paler, 

 the eyes black ; densely, very finely, the elytra more distinctly, punctate. 

 Head rather small, the eyes moderately large ; antennae slender, joints 2 and 3 

 short, equal, those follov^dng elongate. Prothorax convex, ample, rapidly, 

 arcuately narrowing from the base, deeply sinuate opposite the eyes in front. 

 Elytra long, feebly rounded and sharplj^ margined at the sides, with an indi- 

 cation of a sutural groove, the apices somewhat acuminate and depressed near 

 the suture within. Posterior coxal plates subrectangular. Posterior legs com- 

 paratively short, the tibiae curved, moderately widened, and sharply carinate, 

 the spurs short, curved, stout, the upper one not much longer than the lower 

 one, and much shorter than the first tarsal joint. 



Length 4^, breadth 2f mm. 



Hah. Beazil, Kio de Janeiro (Fry). 



One female. An oblong, luteons, finely-punctured insect, resembling 

 a large Cyjjhon, with the posterior tibial s^Durs shorter than usual in the 

 genus Scirtes. It is narrower and much less rugose than the insect here 

 referred to *S'. cayennensis Guer., and Jai'ger and more elongate than 

 S. championi Pieado, from Costa Rica. 



7. — Scirtes hucMeyi, n. sp. 



$. Oblong-oval, convex, very shining, sparsely, finely pubescent; black, 

 the head and prothorax rufo-testaceous, the anterior and intermediate femora 

 (except at the tip) testaceous, the tibiae and tarsi piceous; sparsel}', minutely, 

 the elytra somewhat coarsely, punctate, the punctures on the latter becoming 

 finer towards the apex. Head moderately broad, the eyes large [joints 3-11 

 of antennae wanting]. Prothorax short, convex, rapidly, arcuately narrowing
