I'horax with pronotal width equal to or less than transocular width 

 of head, lateral margins subparallel, disc coarsely punctate except 

 submarginal area near anterior margin; scutellum not, or obscurely, 

 transversely striate on posterior half, otherwise as in Deselvana. Forewing 

 with membrane including nearly all of apical cells in non-teneral 

 specimens, veins distinct, clavus densely, corium sparsely punctate, 

 with four apical cells, the relative position of bases of third and fourth 

 apical cells variable, otherwise as in Deselvana. Hindwing as in Deselvana. 

 Front legs with tibiae slightly expanded and flattened apically. Hindlegs 

 as in Deselvana. 



Male genitalia: Pygofer and plates as in Deselvana, but with macro- 

 setae occasionally abundant, occasionally with only a few microsetae, 

 and with plates distinctly shorter than pygofer. Other genital characters 

 much as in Deselvana. 



Female abdominal sternum VII strongly produced, with lateral 

 margins convergent apically and apical margin weakly trilobate. 



Melichar and others have distinguished species of Rhaphirrhinus 

 primarily on the basis of color. I have found all sorts of variation and 

 intergradation in color and soine variation in size, but with no support- 

 ing morphological characters, these being also somewhat variable. The 

 genus is considered to include only a single species. Rhaphirrhinus is 

 closely related to Deselvana but differs in its conspicuous head process. 



A specimen without abdomen in the Moravian Museum in Brno is 

 here designated lee to type of Rhaphirrhinus vagatus Melichar. It bears the 

 following labels: "Museum Paris/Trinidad/Santa-Anna/Bourgoin 1901" 

 and "vagatus M./det. Melichar." and "Collectio/Dr. L. Melichar/ 

 Moravske museum Brno" and "Raphirhinus/vagatus/det. Melichar."
