cell much sninllir than second ; fourth furcal almost as long as second cubital, 

 strongly curved and terminating below apex of wing; radius rather short; pteros- 

 tigmal space closed, rather short and broad ; cubital petiole shorter than discoidal 

 subcosta, as long as basal subeosta. 



Male — Abdomen moderatelj' stout. Genital segment large; claspers long, 

 strongly curved, obtuse at apex; auxiliary claspers shorter, very acute; anal valve 

 quite large, vertically almost as long as genital plate, with a short, large, pos- 

 terior lobe ; pubescence moderate. 



This species resembles quite closely C. rosirata Crawf. and may possibly be 

 the male of that species, although this is quite improbable. 



Described from one male collected by C. F. Baker at Acapulco, Mexico. 



Epicarsa n. gen. 



Head small ; vertex flat, quite strongly birostrate ; anterior ocellus at base of 

 excision, easily visible from above; posterior ocelli anterior. Labrum small, pos- 

 terior; rostrum comparatively short. Antennae very stout and thick, relatively 

 short; basal segments largest. Pronotum quite long, flat. Dorsulum long. Wing* 

 rather rounded at apex, otherwise similar to subfamily type.

 "' (Figure 157, G, H; 159, D; 160, F) 



Length of body 2.0 mm.; length of forewing 2.9 mm.; greatest width 1.3 mm.; 

 width of vertex between eyes .43 mm. ; with eyes .75 mm. General color dark 

 brown or black; head and prothorax jet black; abdomen lighter; genitalia yel- 

 lowish brown. 



Head not deflexcd, with eyes almost as broad as thorax, finely punctate ; occipital 

 margin straight, emarginate at median suture, not elevated narrowly; vertex dis- 

 cally quite plane, slightly elevated near eyes on postocellar regions, scarcely im- 

 pressed; very deeply excised on anterior margin at median suture, strongly bi- 

 rostrate; with a conspicuous tuberculous epiphysis near eye over insertion of an- 

 tennae ; postocular portion of occiput not large. Facial cones entirely wanting ; 

 antennal bases scarcely swollen ; gense not prominent. Labrum very small, pos- 

 terior, inconspicuous ; rostrum relatively rather short and quite stout. Eyes quite 

 large ; posterior ocelli reniform, anterior ; anterior ocellus in front at apex of ex- 

 cision, visible from above. Antennae not long, very stout and thick; two basal seg- 

 ments very large; third about as long as first two together; scarcely pubescent. 



Prothorax quite strongly arched, broad, coarsely punctate. Pronotum long, flat 

 on dorsal surface ; pleurites very large and long ; pleural suture oblique, almost as 

 long as episternum ; forecoxae large, mostly visible. Dorsulum long. Post-tibial 

 spur not very long, conspicuous. JVings large, hyaline, shining, less than two and 

 one-half times as long as broad, quite broadl}' rounded at apex; first marginal cell 

 very much smaller than second ; second very large ; radial cell short, broad, pe- 

 culiarly rhomboidal ; radius angulate midway, almost contiguous with furcation 

 of second cubital ; without pterostigma ; cubital petiole shorter than discoidal sub- 

 costa; with a prominent black band along tliird furcal and distal half of radius; 

 a black band along second furcal, and a third on radial subcosta.
