Type: Holotype, male (author's collection ex. Univ. California, 

 Davis collection), Cocoa, Fla., July 1944, G. E. Bohart. 



Remarks: This species is related to brachyrhynchus, but differs in 

 having the dark front and facial grooves, and the reddish face, humeri, 

 scutellum, legs, and abdominal segments 2, in great contrast with the 

 very blacldsh thorax, distal abdomen, and tarsi. The female should 

 have the small thee a of brachyrhynchus. 



Physoconops (Pachyconops) cubanus Parsons 



PhysocoJiops cubanus Parsons, Psyche, vol. 47, p. 35, 1940. 



This species belongs to the brachyrhynchus group, having the small 

 theca and the wing pattern extending into the first posterior cell. 

 Because of the rufous on the wing pattern it superficially resembles 

 pictus, but it is otherwise unrelated. 



Range: Cuba. 



Material examined: Cuba: Guabairo, Sept. 2, 1930, R. Dow, 

 1 female (paratype, MCZ); Soledad, Aug. 27, 1929, J. G. Meyers, 

 1 male (BM).
