WEST INDIAN APHODIINAE — CHAPIN 41 



closely punctured. Anterior trochanters triangular, very prominent. 

 Posterior femur slender, with short posterior marginal groove in 

 apical two-fifths, surface finely and rather sparsely punctured. 

 Length : 4.5 mm. 



Tyye and paratypes.—V.S.^M. No. 53329. 



Type locality. — Baragua, Camaguey, Cuba. 



Matei^ial examined. — Three specimens from Cuba, two of which 

 were taken at the type locality May 24, 1932, by L. D, Christenson, 

 the third at Santiago de las Vegas, July 20, 1924, and submitted for 

 study by S. C. Bruner. 



Tliis specie,s be^irs a striking resemblance to E. formica Hinton but 

 differs from that species as follows: The explanate margins of the 

 pronotum end abruptly at the widest point and are not continued 

 posteriorly in such a way as to be visible from above ; the median por- 

 tion of the metasternum is almost impunctate and not evenly and 

 densely punctate ; the posterior marginal groove of the po3terior femur 

 is definitely less than half as long as the femur instead of fully half 

 its length. 



ADDENDA 



Since the preparation of the taxonomic portion of this paper was 

 completed, a few descriptions of Cuban Ataenius by Dr. V. Balthasar ^ 

 have come to my attention. It appears that Dr. Balthasar has not 

 access to the recent literature dealing with this group and has per- 

 haps redescribed certain already known species. 



The species described by Dr. Balthasar are as follows : 



Ataenius waltherhomi Balthasak, 1938, loc. cit., p. 55. 



I find it impossible to separate this from A. darlingtoni Hinton, 

 1937, a species commonly found on Cuba and elsewhere. 



Ataenius havanensis Balthasar, 1938, loc. cit., p. 56. 



The species appears to me inseparable from A. miamii Cartwright, 

 1934. Up to the present I have not examined specimens of this spe- 

 cies from Cuba but have established its distribution in the West 

 Indies as sufficiently wide to make its presence on the island extremely 

 probable. The Florida .specimens are almost certainly recent arrivals 

 from some West Indian island. 



Ataenius frnnkenbergeri Baxthasab, 1938, loc. cit., p. 56. 



This is the species that I have here considered to be A. sulcatulus 

 (Chevrolat). While the identification is not fully established, suf- 

 ficient variation in the series from Baragua was noticed to make such 

 an identification highly probable.
