526 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Hispaniola: HAtxi, Roche Croix (Darlington, in M.C.Z.) ; Dominican Republic, 

 Valle Nuevo (Darlington, in M.C.Z and U.S.N.M.), Constanza (Darlington, 

 in M.C.Z. and U.S.N.M.). 



Puerto Rico: El Tunque (Darlington, in M.C.Z. and U.S.N.M.). 



Montserrat: (Hubbard, in U.S.N.M.). 



Guadeloupe: (Bernhauer, 1918, as vitraci; Busck, in U.S.N.M.), 



St. Vincent: (British Museum). 



Trinidad: Tacarigua (Blackwelder station 107C), Guepo Bay (Darlington, in 

 M.C.Z.). 



South America: Colombia (Erichson, 1839b). 



Specimens examined. — I have seen 2 examples in the British 

 Museum, 18 from the Museum of Comparative Zoology, 15 in the 

 United States National Museum, and 5 collected by me during 

 1935-37. 



Remarks. — I am unable to distinguish the species recently named 

 by Bierig from Cuba or that of Bernhauer from Guadeloupe. The 

 characters used seem to me to be variable and all extremes are to 

 be found in the series before me. I have hesitated to reduce to 

 synonymy the two species I have not seen {cuhanus and cariheanus) 

 but find no other procedure tenable on the information at hand. 



My examples were taken from under moss and dirt on a rock 

 beside a stream and from fungus (Hydnum sp.). 



LXXXVIII. Genus BRYOPORUS Kraatz 



Bryoponis Kkaatz, lS57a, p. 452. 

 Subgenus Bryophacis Reixter, 1909, p. 102. 



Genotypes. — Tachinus cemuus Gravenhorst = BryoporiLS cemuus 

 (Gravenhorst) (designated here). Of Bryophacis^ Bolitohius rufus 

 Erichson = Bryoporus {Bryophacis) rufus (Erichson) (designated 

 by Tottenham, 1939.) 



Diagnosis. — Head inclined, strongly margined beneath the eyes; 

 antennae inserted at sides in front of eyes, 11-segmented, outer seg- 

 ments pubescent from the fourth joint; hypostomal suture present, 

 coronal suture absent ; labrum rather large, subquadrate ; palpi stout, 

 fourth segment of maxillary about as long as third, conical; gular 

 sutures widely separated; anterior coxal cavities entirely open behind; 

 front coxae very large, exserted; posterior coxae contiguous, "trans- 

 verse," expanded laterally and caudally under the femora; first and 

 second abdominal sternites absent; tarsi 5-segmented, first segment 

 of posterior moderate or short. 



Remarks. — This small genus is structurallj' very close to BoUtohius 

 but can be distinguished by its equal spinules at the apex of the tibiae 

 and by the conical fourth segment of the maxillary palpus. 



I have seen 21 examples from the West Indies representing 7 

 species, of which 6 appear to be new.
