164 Psyche [October 



Described from a single specimen taken at Diquini in a nest of 

 Aphocnogaster relicta. The only other West Indian Fustiger is F. 

 smithi Raf. from St. Vincent. F. haytiana differs in being larger 

 (s77iithi is only 1.65 mm. in length) and in not having the elytra 

 rugosely punctate at base. 



Family Lathridiid^. 

 Coluocera maderae Woll. 



Taken in numbers at Manneville, in company with Prenolepis 

 longicornis. 



This beetle was first described from Madeira, where it was 

 found in the nest of an ant. The name of the host was not given, 

 but Wasmann reasonably supposes that it was Prenolepis longi- 

 cornis. This author has given an interesting account of the beetle 

 (Zeitschr. f. wiss. Insektenbiol. 1905, pp. 384-390), in which he 

 records it from India, Para, Brazil, and the island of Trinidad as 

 well as from Madeira. In each locality it occurs with Prenolepis 

 longicornis, but in India it has been found also with P. indica 

 Forel and also with species of the genus Pheidole, however, usually 

 with the first named ant. Assmuth notes (Zeitschr. f. wiss. In- 

 sektenbiol. 1907, p. 330) that at Bombay, India, it is very abun- 

 dant, while rare at Khandalo. In Hayti about Lake Assuei it was 

 abundant, but sporadic. Dozens of specimens occurred in some 

 nests while in the immediate vicinity others would not contain 

 a single individual, and although the host ant is common through- 

 out the island at the lower altitudes, I did not find the beetles in 

 any other locality.

 and legs exclusive of the outer side of the front coxse, which are rufous, and the apical
