1. BRYOPORUS REGULUS, new species 



Description. — Black or piceous, edges sometimes rufescent. Head 

 suborbiciilar, deflected; without distinct punctures on the disk but 

 with irregular minute punctulae sometimes in clusters; without 

 ground sculpture. Pronotmn two-sevenths wider than long, widest 

 at basal fourth; basal angles obtuse but distinct; strongly convex; 

 with a single pair of large discal punctures at apical third and scat- 

 tered rather coarse punctulae; without ground sculpture. Elytra 

 with very large but very shallow punctures, excavated behind, in 

 eight longitudinal series, the fifth, sixth, and seventh not perfectly 

 regular but readily traceable; without ground sculpture. Abdomen 

 with punctures finer than on elytra and often submuricate; without 

 ground sculpture. Length, Si/o to 6 mm. 



Type locality. — Dominican Republic, cloudforest in the vicinity of 

 Valle Nuevo; elevation about 6,000 feet. 



Types. — Holotype and three paratypes in the Museum of Compara- 

 tive Zoology ; four paratypes in the United States National Museum 

 (No. 62543); collected in August 1938 by Dr. P. J. Darlington. 

 (Paratypes partly from localities listed below.) 



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



Hispaniola: Haiti, La Visits (Darlington, in M.C.Z.) ; Dominican Republic, 

 Valle Nuevo (Darlington, in M.C.Z. and U.S.N.M.), foothills south of San- 

 tiago (Darlington, in M.C.Z. and U.S.N.M.) ; Stinchez (Darlington, in 

 M.C.Z. and U.S.N.M.), San Jos(5 de las Matas (Darlington, in M.C.Z.), 

 Constanza (Darlington, in M.C.Z.). 



Specirnens examined. — I have seen the eight types and two other 

 specimens from the Museum of Comparative Zoology. 



Remarks. — This species is distinguished as outlined in the key. It 

 attains the largest size of any so far taken in the West Indies. 



The type was taken in cloudforest, but I have received no other 

 record of the habits of this species.
