Holotype male, on agave, Merida, Yucatan, Mexico, Sept. 13, 1946, 

 "16924" (E. J. Hainbleton), one female, and one specimen, same data, 

 without abdomen (USNM); five specimens, Merida, Yucatan (NCS). 



This species is named in honor of Dr. E. J. Hambleton, whose collect- 

 ing activities in the American tropics have contributed much to add 

 to our knowledge of the neotropical fauna in various groups of insects. 



This species appears to be related to H. ichthyocephala (Signoret), 

 but can be distinguished from that species by the falcate dorsal and the 

 very short ventral aedeagal processes, both of which are different in 

 H. ichthyocephala.

Figures 191, 192 

 Propetes Walker, 1851a:797. Type-species: P. compressa Walker, by monotypy. 



Length 12.5-16.5 mm. 



Head strongly produced, its median length from slightly less to slightly 

 greater than interocular width and approximately six-tenths transocular 

 width, anterior margin very broadly rounded and with a weak median 

 apical carina, without a carina separating crown from face, ocelli 

 located on or slightly before a line between anterior eye angles, each 

 slightly closer to median line than to adjacent eye angle, without an 

 M -shaped elevation bordering posterior margin, disc with fine close-set 

 pubescence; antennal ledges very slightly protuberant in dorsal aspect, 

 each with a shallow longitudinal depression, carinate dorsally in lateral 

 aspect, anterior margin oblique; clypeus strongly flattened medially, 

 texture of its dorsomedial area longitudinally striate, face finely 

 pubescent above, densely pubescent below, otherwise as in Phera. 



Thorax with lateral margins divergent anteriorly, disc rugose, with 

 or without pubescence, in lateral aspect with an oblique incomplete 

 dorsopleural carina which is very slightly bisinuate, proepimeron with 

 ventral margin not or only slightly depressed and with length much less 

 than width; posterior portion of scutellum swollen and not striate. 

 Forewing completely hyaline except fumose commissural area in basal 

 portion of clavus, surface without sculpturing, middle anteapical cell 

 with or without supernumerary crossveins, otherwise as in Phera. 

 Hindwing extending posteriorly as far as bases of apical cells of forewing, 

 otherwise as in Phera. Hindlegs with femoral setal formula 2:0:0; first 

 tarsomere with length greater than combined length of second and third 

 tarsomeres; other leg characters as in Phera. Abdomen constricted 

 basally. 



Male genitalia: Pygofer not strongly produced, very broad, posterior 

 margin regularly convex, with a number of irregularly dispersed
