eus ; third segment of maxillary palpi much enlarged, somewhat com- 

 pressed, fourth small. Pronotum nearly one-eighth wider than long, 

 sides parallel in anterior two-thirds, thence feebly rounded to base; 

 midline rather coarsely channeled; surface impunctate but set with 

 tiny rounded Uiberculi throughout; ground sculpture rather feeble 

 but coarsely scaly. Elytra dehiscent in apical fourth, rather nar- 

 rowly rounded at both posterior angles; with very large shallow 

 punctures separated by half their diameter or less, intervals flat. 

 Length, 4i/4 mm. 



Type locality. — St. Croix, along a stream 1 mile northeast of Sprat 

 Hill Estate. 



Types. — Holotype, U.S.N.M. No. 52371, collected by me on October 

 81, 1936. 



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



Vieques Island: (Leonard, in U.S.N.M.)- 

 St. Croix: (Blackwelder station 315). 



Specimens examined. — I have seen only the unique type and one 

 other specimen. 



Remarks. — I found the type of this distinct species while collecting 

 with Harry Beatty of St. Croix and take pleasure in naming it in 

 his honor. 



Another specimen, which I associate with the type, was taken on 

 Vieques Island on April 28, 1930, by Dr. M. D. Leonard. It diifers 

 only in lacking the definite posthumeral luteous stripe. The species is 

 distinct from any that I know in having the punctures of the head 

 and pronotum replaced by rounded tuberculi. 



I collected the type under a stone at the edge of a small stream in 

 the woods. 



8. BLEDIUS CERATUS, new species 



Description. — Testaceous, head and apex of abdomen piceous. Head 

 flattened above with a very large and deep transverse depression 

 behind the eyes, and an impressed line at front of eyes separating 

 clypeus from vertex; on each side immediately above eyes with tw^o 

 erect horns, more than half as long as space separating the pairs ; first 

 segment of antennae nearly three times as long as second; surface 

 not punctate but with coarse scaly sculpture; labrum nearly three 

 times as wide as long, rounded in front; third segment of maxillary 

 palpi enlarged, but not noticeably flattened, fourth small. Pronotum 

 parallel in apical two-thirds, thence rapidly narrowed to base but not 

 arcuate; anterior margin prolonged at middle into a slender porrect 

 horn fully one-half as long as disk; midline finely channeled; with 

 regular and moderately coarse punctures obscured by the strong scaly 

 ground sculpture. Elytra broadly rounded behind laterally, but more 

 narrowly rounded at suture; with coarse regular punctures, rather
