and in hrachyrhynchus if abdominal segment 2 is black the remainder 

 of the abdomen is black. In addition, the theca is larger and more 

 robust than in gracilis and hrachyrhynchus, but not as long as in 

 excisus or hulhirostris. 



Physoconops (Pachyconops') pictus (Fabricius) 



Conops pictus Fabricius, Entomologia systematica, vol. 4, p. 39, 1794. 



This distinctive species has a very large theca that is reddish with 

 golden pollen. There is sometimes slight darkening on the medial 

 side of antennal segment 3. The color of the basal cells is as dark as 

 the remainder of the wing pattern. The dorsum of the thorax has the 

 yellow extending back partly dividing the black into three stripes, 

 and forming one large or two smaller yellow spots.

Physoconops (]P achy conops) ramondi (Bigot) 



Conops ramondi Bigot, Diptera, in de la Sagra, Historia . . . natural de la Isla 

 de Cuba, pt. 2, vol. 7, p. 808, 1857. 



This species differs immediately from pictus by the very large size. 

 The thorax is rufous with small dark markings. The third antennal 

 segment is dark reddish with some black laterally and mostly blackish 

 medially. The abdomen is dark reddish with very little golden pollen. 

 The theca is large as in pictus, and the basal cells are as dark as the 

 rest of the wing pattern. The postoccipital stripe is absent in this 

 species as well as in pictus. 



Range: Cuba. 



Material examined: Cuba: Guantanamo, June 21, 1910, 1 female 

 (MCZ). 



Physoconops (Pachyconops) bahaniensis Parsons 



Physoconops hahamensis Parsons, Psyche, vol. 47, p. 29, 1940. 



This species has not been examined but presumably belongs to this 

 subgenus. It is known only from the type female. It appears to be 

 related to guianicus, and has the same large theca. In the original 

 description the second abdominal segment was omitted. Darlington 

 informs me that it is reddish brown. 



Range: Bahama Islands.
