1. ECHIASTER MICROPS, new species 



Description, — Rufous to rufotestaceous, head, pronotum, and abdo- 

 men somotinies pice.scoiit in part, elytra with apical half black. Head 

 moderately large, siibquadrate ; eyes very small, at nearly twice their 

 length from base; no punctures visible, but sculpture very dense and 

 granulose and (nberculosp; antennae short, segments 7 to 10 trans- 

 verse. Pro'iiotum. nearly four-fifths as wide as head, as broad as long; 

 widest at anterior third, thence abruptly narrowed to neck, moder- 

 ately narrowed to base; disk longitudinally impressed on each side 

 of midline, leaving a distinct elevated convex ridge; sculpture similar 

 to that of head. Elytra as broad as long, one-third longer than pro- 

 notum ; sculpture similar to that of head and pronotum but with very 

 fine pubescence. Abdomen near base wider than elytra, narrower 

 posteriorly ; with moderately fine but not dense subnmricate punctures ; 

 pubescence rather long apically. Male, eighth sternite feebly broadly 

 emarginate. Fenuile^ eighth sternite broadly rounded. Length II/2 

 to 21/4 Jnm. 



Type locality. — Montserrat. 



Types. — Holotype, female, and one paratype, female, U.S.N.M. 

 No. 52403, collected in February and March by H. G. Hubbard. 



Records. — The following are the records known to me : 



[Cuba: Cayamas (Scliwarz, in U.S.N.M.).] 

 Montserrat: (Hubbard, in U.S.N.M.). 



/Specimens examined. — I have seen the two types and one otlier 

 specimen. 



Remarhs. — The Cuban example is placed with this species with 

 some doubt. It is considerably larger but seems to differ otherwise 

 only in the less distinct pronotal impressions and slightly more 

 rounded pronotum. 



The sculpture of the forebody has been examined with a binocular 

 microscope at a magnification of over 200 diameters. At this and 

 all lower magnifications it appears to be densely granulose and tuber- 

 culose. 



I find no record of the habits of this species.

 rate, longer than broad, posterior angles rounded ; eyes rather small ; 

 temples large, longer than diameter of the eyes; punctation close,
