AfcWiius fratr.r, sp. n. 



A. strkjicavdae forma et magnitudo, sed differt capite crebre 

 punctato, hand ruguloso, elytrorum interstitiis minus coiivexis, 

 sparsissime punctulatis, metasterno femoribusque omnibus disperse 

 et grosse p»unctatis. 



Long. 5-5'5 mm. 



Hob. St. Vincent, South end ; Grenada, Leeward side. 



At first sight this species is indistinguishable from 

 A. strigicauda, but a close examination reveals slight 

 differences which in combination sufficiently establish its 

 distinctness. Tlie punctures on the head are very fine, 

 and, though not uniformly distributed, are everywhere 

 distinct, and do not change into wrinkles anteriorly as in 

 A. strigicauda. The elytral interstices show lateral stria3 

 behind, as in that species, but unlike it the interstices are 

 strewn with minute punctures. The evenly-punctured 

 surface of the metasternum and middle and hind femora 

 perhaps constitute the most evident difference between 

 the two, these in A. strigicauda being smooth except for 

 clusters of about half-a-dozen punctures on each side of the 

 median furrow of the metasternum and at the distal 

 extremities of the femora. 



This appears to be a very local species, but considerable 

 numbers were found at the southern end of St. Vincent 

 and a few specimens in Grenada (Grand Etang Lake and 

 Mount Gay Estate). It occurred under the same conditions 

 as the allied form, but in different places. 



At^nius tcrminalis, Chevrolat. 



Numerous specimens were found in Grenada of the form 

 referred to by Chevrolat as inhabiting most of the Antilles. 

 Its apparent absence from St. Vincent is rather remarkable. 

 All our specimens have the yellow border extending round 

 the elytra from shoulder to shoulder. 



Atxnius tenchrosus, sp. n. 



Niger, opacus, griseo-vestitus, latus, parum convexus, capite densis- 

 sime rugose punctato ; prothorace creberrime sed distincte punctato ; 

 elytris striatis, striis hand profunde punctatis, interstitiis subcari- 

 natis, baud setosis ; prothoracis Lxteribus medio fere rectis, angulis 

 omnibus arcuatis, 



Lat. 2 mm. Lons. 4*5 mm.
