is therefore restored to the American lists with three subgenera, and 

 the remaining names are grouped under Homoeotarsus and Biocrypta. 



Cryptohium, centrale Sharp of Central and South America is listed 

 by both Bernhauer and Scluibert and Leng and Mutcliler as occurring 

 in Guadeloupe. It is at least likely that this is a misidentification, but 

 I am not able to say to which of our species (or genera) it really 

 pertains. 



Inasmuch as the name Ochthephilum has priority over Gryptohiurn 

 (and the two are isogenotypic) , the former must be accepted as the 

 valid name for this genus. 



I have seen only three examples of this genus from the West Indies. 

 They belong to two new species, and one other species has been recorded 

 from Cuba and one from Trinidad. 



KEY TO WEST INDIAN SPECIES OF OCHTHEPHILUM 



1. Eyes at not over twice their length from base ; basal segment of antenna longer 



than interantennal distance 2 



Eyes at four times their length from base ; basal segment of antenna as long 

 as interantennal distance 3. darlingtoni 



2. Basal segment of antennae twice as long as interantennal distance ; head very 



strongly narrowed in front 2. trinitatum 



Basal segment of antennae one-half longer than interantennal distance ; head 

 feebly narrowed in front 1. atlanticum 



1. OCHTHEPHILUM ATLANTICUM (Bierig) 



Vryptohiella atlantica Biebio, 1935b, p. 41, pi. 4, figs. 8, 9, 10. 



Description. — Piceous, anterior and posterior margin of pronotum 

 rufescent, apex of elytra testaceous. Head not greatly narrowed in 

 front of eyes; punctures moderately large, umbilicate, clearly im- 

 pressed on disk, somewhat sparse on clypeal area, intervals on vertex 

 narrower than punctures ; with dense ground sculpture ; with a feeble 

 epicranial depression with clustered punctures; ej^es at or a little be- 

 hind the middle ; basal segment of antennae about four-fifths as long as 

 head but only one-half longer than distance between antennae; an- 

 tennal grooves distinct; labrum scarcely emarginate and with two 

 minute denticles ; neck one-half as wide as head. Pronotum with punc- 

 tures denser than on head, somewhat vague and subserial ; with a broad 

 smooth median band, canaliculate posteriorly; with ground sculpture, 

 Male., seventh sternite feebly emarginate and with disk impressed; 

 eighth with a narrow excision nearly three times as deep as width at 

 apex. Length, 5 to 6 mm. (From Bierig.) 



Type locality. — Cuba, "Embocadura del Rio Cojimar: Playa de 

 Marianao." 



Types. — In collection of Alexander Bierig. 



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



Cuba: Rio Cojimar, Playa de Marianao (Bierig, 1935).
