(and feebly emarginate) to base with an angulation at anterior two- 

 fifths, base and basal angles broadly rounded ; smooth except for two 

 discal series of five moderately coarse punctures and a recurved lat- 

 eral series of six; with obsolescent ground sculpture. Elytra with 

 moderately coarse sparse punctures arranged in series on outer half 

 only. Abdomen with sparse irregular submuricate punctures except 

 along middle; with feeble transverse strigulose ground sculpture. 

 Length, 5 to 6 mm. 



Type locality. — Haiti, La Visite and vicinity, in the La Selle 

 Range; elevation 5,000 to 7.000 feet. 



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

 tive Zoology; four paratypes in the United States National Museum 

 (no. 52:)23) ; collected on September 16-23, 1934, by Dr. P. J. Dar- 

 lington. 



Records. — The following is the only record known to me : 



Hispaniola: Haiti, La Visits (Darlington, in M.C.Z. and U.S.N.M.), Morne Trou 

 d'Eau (Darlington, in M.CZ ). 



Specimens examined. — I have seen only the types and one example 

 from the Museum of Comparative Zoology. 



Remarks. — This species may be distinguished by the regular pro- 

 notal series, by the more or less distinct uniting of the postantennal 

 gi'ooves by a depression, and by the sculpture of the head. 



I have received no record of its habits. 



8. XANTHOLINUS RULOMUS, new species 



Description. — Black, elytra dull piceous with base testaceous. 

 Head about one-eleventh longer than wide, nearly parallel, basal 

 angles moderately rounded but with a slight interruption; eyes

 grooves moderately impressed and irregularly united at apex by 

 an arcuate depression, not distinctly punctate; Avithout additional 

 postantennal or ocular grooves; with sparse elongate umbilicate 

 punctures interspersed with large punctulae; with irregular strigu- 

 lose ground sculpture. Pronotum about one-third longer than wide, 

 widest along anterior two-fifths, thence feebly narrowed and emar- 

 ginate posteriorly, base and basal angles broadly rounded; dorsal 

 series of six punctures arranged in pairs; recurved lateral series of 

 seven or eight; otherwise smooth except for obsolescent strigulae at 

 sides. Elytra with rather coarse punctures not serial except for one 

 series on disk but obscured by dense granulose ground sculpture. 

 Abdomen with sparse moderate umbilicate punctures except along 

 middle; with very feeble transverse strigulose ground sculpture. 

 Length, 5 mm. 



Type locality. — Dominican Republic, Jarabacoa ; elevation 1,500 to
