WEST INDIAN APHODIINAE — CHAPIN 35 



Metasternum opaque and finely sculptured at sides, shining and very 

 coarsely punctured on median area, median groove moderately deep, 

 abruptly terminated anteriorly. Abdominal sternites sparsely and 

 rather finely punctured, basal transverse rows of pits poorly defined. 

 Anterior femur with deep perimarginal groove, surface coarsely and 

 densely punctured. Middle femur with posterior marginal groove. 

 Posterior femur without marginal groove, surface shining, coarsely 

 and sparsely punctured, the punctures almost entirely in apical half ; 

 posterior tibia with accessory spine. Length: 3.7 mm. (given as 

 4 mm. by Hinton). 



Type.— U.S.N.M. No. 53327. 



Type locality. — Diquini, Haiti. 



Material examined. — A single specimen, the type, which was col- 

 lected at the above locality by J. B. Torres. 



A species notable for the fact that the middle and hind femora are 

 quite different. It is the rule in Ataenius that these femora are 

 similar.

Piceous, sides of pronotum, outer intervals and apical third of 

 elytra, antennae, and trophi pale reddish to yellowish brown, some- 

 what shining. Anterior margin of head broadly rounded each side 

 of the moderately deep median emargination, front finely and irregu- 

 larly rugulose with numerous fine punctures mtermingled, vertex 

 much more coarsely and rather densely punctured. Pronotum with 

 marginal row of setae complete, the setae near the anterior angles 

 longer, marginal groove complete and coarse. Surface closely and 

 at sides cribrately punctured, the punctures of two sizes — very coarse, 

 which are quite sparse on disk, and moderately fine, which are evenly 

 though rather sparsely distributed over the entire pronotum except 

 where the coarse punctures coalesce. Elytral striae deep, strial 

 punctures moderately coarse, intervals convex but not at all carinate, 

 each interval with two or three irregular rows of minute punctures, 

 apical portions of all intervals and entire outer two intervals with 

 fine setae, surface not strongly alutaceous. Lateral margin sub- 

 carinate, setose, epipleura somewhat shining. ^ Pygidial carina with 

 strong median cusp. Mesosternum finely sculptured, metasternum 

 shining, laterally with a small patch of punctures near the epimeron, 

 median portion flattened, finely and rather sparsely punctured, 

 median groove deep, abruptly termmated anteriorly and porteriorly. 

 Abdominal sternites coarsely and rather densely punctured, trans- 

 verse basal row of pits on last sternite coarse and deep. Anterior
