the other specimen), otherwise as in H. noressa. Hindlegs with femoral 

 setal formula 2:1:0, otherwise as in H. noressa. Male pygofer short, 

 posterior margin regularly, slightly convex, process poorly developed; 

 plates very broad and short with apex curved dorsally, not extending 

 as far posteriorly as pygofer apex ; connective Y-shaped with stem short 

 and carinate, arms widely divergent ; aedeagus with two pairs of proc- 

 esses, the dorsal pair elbowed and avicephaliform in lateral aspect, 

 the ventral pair much shorter and abruptly tapering. Color of crown, 

 pronotum, and scutellum sordid pale brown, otherwise as in H. noressa. 

 Female abdominal sternum VII with a shallow median regular con- 

 cavity on posterior margin. 



Holotype male, Esquinitla, Guatemala, May 27, 1923 (E. G. Smyth), 

 and two females, Ayutla, Guatemala, (USNM). 



In structure of the genitalia this species is closely related to H. ichthyo- 

 cephala (Signoret), but it can be distinguished from this and all other 

 species by the shape of the dorsal aedeagal processes.

Length of male 10.9 mm.; of female 12.4 mm. Head with median 

 length of crown almost equal to interocular width, somewhat angulate 

 at transition from crown to face, disc without an M -shaped elevation 

 bordering posterior margin, without pubescence (specimens possibly 

 rubbed), other characters as in H. noressa, new species. Thorax with 

 dorsopleural carinae complete (type) or incomplete. Forewing hyaline, 

 without sclerotized areas (type) or with a slight, poorly delimited 

 sclerotized area near base of outer tv/o anteapical cells, with one or 

 more supernumerary crossveins between veins M and Cuj. Hindlegs 

 with femoral setal formula 2:1:0, otherwise as in H. noressa. Male 

 pygofer short, posterior margin slightly and regularly convex, ventral 

 process poorly developed ; male plates acute apically, extending almost 

 as far posteriorly as pygofer apex; style without distinct preapical lobe, 

 apex with a slight angular median projection; connective Y-shaped 

 with stem short and carinate, arms widely divergent; aedeagus with 

 preatrium elongate, shaft with a pair of dorsal processes which are 

 falcate apically, and a pair of greatly reduced angular ventral processes. 

 Color of crown and pronotum rich brown with disc of latter darker 

 posteriorly, scutellum almost unmarked brown (type) or brown marked 

 with paler brown flecks; sclerotized portion of forewing black when 

 present; venter sordid yellow with irregular dark markings. Female 

 abdominal sternum VII moderately produced, posterior margin with 

 a V-shaped median emargination.
