13. PHILONTHUS TRINITATIS, new speciei 



Description. — Head piceous, pronotum piceorufous, elytra rufous 

 but paler at base, abdomen rufous with fourth and fifth visible seg- 

 ments piceous. Head (including eyes) one-sixth wider than long, 

 suborbicular, hind angles scarcely traceable ; eyes at a little less than 

 their length from base ; with a strong median longitudinal depression 

 in anterior half; disk with two punctures forming (with two supra- 

 ocular) a nearly straight row of four between the eyes, and with scat- 

 tered very coarse punctures at sides and base ; without ground sculp- 

 ture. Pronotum one-third longer than wide, widest near front angles, 

 feebly emarginately narrowed to basal angles, which are moderately 

 rounded, base truncate; with discal series of five or six punctures (and 

 another anterior pair which is not truly marginal) very deep and 

 coarse, nearly umbilicate, and with five or six lateral punctures ; with- 

 out ground sculpture. Elytra with rather coarse punctures separated 

 by less than their diameter ; the surface somewhat rugose but without 

 ground sculpture. Abdomen irregularly but finely and submuricately 

 punctate; without ground sculpture. Male^ unknown. Female^ 

 eighth sternite rounded. Length, 6 mm. 



Type locality. — Trinidad, St. Augustine. 



Types. — Holotype in the Museum of Comparative Zoology. 



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



Trinidad: St. Augustine (Darlington, in M.C.Z.). 



Specimens examined. — I have seen only the holotype. 



Remarks. — This species is not very similar to P. waterhousei. The 

 coloring, the strength of the pronotal punctures, the shape of the head 

 and pronotum, the coarseness of the elytral punctures, and the com- 

 plete lack of any trace of ground sculpture are among the differences. 



I would hesitate to describe a single PhUonthus as new, especially 

 from Trinidad, if it were not so unusual in appearance and structure. 

 None of the South or Central American species known to me are at 

 all similar. The general facies is that of a Bjelonuchu^'^. but the femora 

 are without spines (except for one row on the anterior) and the gular 

 sutures are united only behind the middle. 



I have received no record of its habits.
