cate or very vaguely emarginate; eighth with a broad rounded 

 emargination less than one-third as deep as wide. Female, unknown. 

 Length, 21/^ mm. 



Type locality. — Puerto Rico, 4 miles southeast of Adjuntas, elevation 

 about 3,000 feet. 



Types. — Holotype, male, U.S.N.M. No. 62402, collected by me on 

 October 4, 1935; two paratypes from the Museum of Comparative 

 Zoology, from El Yunque and Maricao. 



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



Puerto Rico: Adjuntas ( Blackwelder station 48A), Maricao Forest (Darlington, 

 in M.C.Z.), El Yunque (Darlington, in U.S.N.M.). 



Specimens examined. — I have seen only the three types. 



Remarks. — This species is named for R. G. Oakley, who was of 

 great assistance to me in the collecting of this and numerous other 

 species. 



This species is quite distinct from ferrugineus.^ but except for the 

 denticles on the labrum it seems to be a normal Sunius s. str. 



The type was found in a very rotten stump. 



2. SUNIUS FERRUGINEUS (Bierig) 



Medonella ferrugtnca Bierig, 1034f, pp. 326, 329, fig. 3. 



Description. — Ferrugineous. Head quadrangular, one-fourth longer 

 than wide (from the figure, about as wdde as long), basal angles 

 rather broadly rounded, base not truncate; eyes separated from 

 base by more than twice their length ; with fine punctures separated 

 by less than their diameter except on the vertex; without dense 

 ground sculpture. Pronotmn as wide in front as head, as broad as 

 long, sides feebly converging behind and rounded into base ; punctures 

 homogeneous, more variable in size, lacking in narrow irregular 

 midline; without dense ground sculpture. Elytra reduced, one- 

 seventh wider than long; much more coarsely and simply punctate, 

 the intervals elevated and very finely irregularly coriaceous. Ahdo- 

 onen with very uneven granulose sculpture. Male., eighth sternite 

 with a large triangular incision. Length, 21/^ mm. (From Bierig.) 



Type locality. — Cuba, Playa fie Marianao. 



Types. — In the collection of Alexander Bierig. 



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



Cuba: Playa de Marianao (Bierig, 1934). 



Specimens examined. — I have seen no examples of this species. 



Remarks. — The characters given in the original description appear 

 to be sufficient to place this species in the key, although its reference ^ 

 to this genus is perhaps doubtful. It appears to belong to the sub- 

 genus Sunius s. str. 



Bierig records this species from sand under dry seaweed.
