Vol. XXV] ENTOMOLOGICAL NEWS. 63 



Body large, robust ; head as broad as thorax, deflexed ; ver- 

 tex broad, more or less cleft in front ; genal cones entirely 

 wanting; frons not covered by genae, but visible as a narrow 

 sclerite from front ocellus to clypeus ; front ocellus above ; 

 antennae short, about as long as width of head. Thorax large ; 

 pronotum very short. Forewings large, hyaline, transparent, 

 acute at apex ; pterostigma unusually large, elliptical ; marginal 

 cells very large ; branching of veins similar in type to Carsi- 

 dara. 



Type of genus: Macrohomotoma gladiatum Kuwayama (loc. 

 cit, p. 180). 



The genus shows a distinct relationship to Carsidarinae, 

 although the head is not so deeply cleft in front and there is 

 no basal spur on the hind tibiae, as there is in many of the 

 other genera placed in this subfamily (Crawford Pomona 

 Journ. Ent., Ill, p. 381, 1911). 



Synopsis of the Species. 



A. Cubital vein before its furcation as long as stem of media 

 and ctibitus ; pterostigma black apically ; female genital segment very 

 short M. gladiatum Kuway. 



AA. Cubitus exceedingly short before furcation, many times shorter 

 than stem of media and cubitus ; pterostigma not black apically ; 

 female genital segment long and slender M. nyasae (Newst.) 



Macrohomotoma nyasae (Newstead). 



Syn. Pseudcriopsylla nyasae Newstead loc. cit. p. 105, 1911. 



Length of body (male) 2.9 mm.; (female) 3.3 mm.; length of fore- 

 wing 5.2 to 5.6 mm. General color reddish brown to chocolate 

 brown ; dorsal portion of scutellum and posterior part of dorsulum, 

 vertex, male genitalia, and legs, lighter brown to ochraceous ; venter 

 of abdomen whitish. 



Head very broad, as broad as thorax, greatly deflexed ; vertex 

 nearly twice as broad as long, coarsely punctate, with a deep fovea 

 on each side of median line posteriorly and a deep sulcus connecting 

 them; front margin somewhat cleft, but not as much as in Carsidara; 

 front ocellus easily visible from above. Genal cones entirely want- 

 ing; frons narrowly visible between genae. Antennae slender, about 

 as long as width of head, black at tip. 



Thorax very large, broad and strongly arched ; pronotum very 

 short, sometimes mostly concealed behind posterior margin of head; 

 dorsulum longer than broad ; raetanotum produced at posterior end
