438 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



next to the series; with strigulose ground sculpture more distinct than 

 on head. Elytra without distinct punctures but densely sculptured, 

 apparently with two sizes of asperities. Ahdomen with fine and mod- 

 erately dense submuricate punctures ; with indistinct ground sculpture. 

 Male^ eighth sternite with a triangular emargination about as deep as 

 wide with outer angles rounded. Female^ eighth sternite rounded. 

 Length, 5 to 6 mm. 



Type locality. — Cuba, Playa de Marianao. 



Types. — In collection of Alexander Bierig. One "cotype" (para- 

 type) is deposited in the United States National Museum (No. 

 52745). 



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



Cuba: Playa de Jlarianao (Bierig, 1934; United States National Museum). 



Jamaica: Bluefields Bay (Blackwelder station 418). 



Puerto Rico: San Juan (Blackwelder station 43A), Humacao (Blackwelder 



stations 55, 56). 

 St. Croix: (Blackwelder stations 326, 336). 

 Antigua: (Blackwelder station 272). 

 Guadeloupe: Basse Terre (Blackwelder station 77A). 

 Dominica: (Blackwelder station 240%B). 

 Grenadines: Carriacou (Blackwelder station 143A). 

 Grenada: (Blackwelder station 163). 



Specimens examined. — I have seen a cotype received from Sr. 

 Bierig and 20 examples collected by me during 1935-37. 



Remarks. — I have compared this species with examples of coralU- 

 Gola from Singapore (identified by Dr. Cameron) and find it to be 

 very similar, if not indistinguishable. However, since I have only 

 one Cuban example and two Singapore ones I do not feel in a posi- 

 tion to decide the variability of the characters that present the slight 

 differences. Until the species in this group can be studied with ade- 

 quate material (and such has not been available to anyone heretofore, 

 as far as West Indian examples are concerned), it seems best to re- 

 tain cariheaniis as a valid species. 



I have found it under seaweed and drift on sandy beaches.
