vertex deeply impressed with two oblique sulca on each side of median suture, one 

 subtransverse and oblique and the otlier extending outward from anterior ocellus; 

 anterior ocellus large, on median suture above the apex of excision ; posterior ocelli 

 well forward ; anterior margin of vertex deeply excised at median suture, making 

 vertex strongly birostrate, antennae inserted at apex of rostrate lobes; basal seg- 

 ments large; flagellum very long, slender, filiform. Facial cones wanting. Genae 

 not prominent. Labrum very small, jjosterior, inconspicuous; rostrum very long, 

 slender, acute. Eyes large. 



Thorax broad, quite long, rather coarsely punctate, not strongly arched. Prono- 

 tum relatively long, flat on dorsal surface; propleurites long, prominent; pleural 

 suture visibly as long as episternum ; forecoxa? quite large, mostly visible. Dorsu- 

 lum relatively short, broad, broadly rounded on both margins; scutum much 

 longer than dorsulum. Post-tibial spur prominent, quite large. JVi7igs relatively 

 large, hyaline, almost three times as long as broad, quite acute at apex ; first 

 marginal cell very much smaller than second ; fourth f ureal almost as long as sec- 

 ond cubital, strongly curved, and terminating below apex of wing; radius long; 

 pterostigmal space closed, quite long and broad; cubital petiole about two-thirds 

 as long as discoidal subcosta, as long as basal subcosta. 



Female — Abdomen stout. Genital segment almost as long as rest of abdomen, 

 large, u|)curved, quite acute; dorsal plate longer basally than ventral; ventral 

 plate strongly upcurved on inferior margin near base ; pubescence moderate. 



Described from three females collected by C. F. Baker in Chinandega, Nica- 

 ragua.

(Figure J 57, B; 158, O; 159, B; 160, E) 



Lcngtli of body 1.9 mm.; length of forewing 2.9 mm.; greatest width 0.9 mm.; 

 width of vertex between eyes .39 mm. ; with eyes .72 mm. General color greenish 

 throughout. 



Head not deflexed ; ])rofile longer than broad, rounded above; with eyes about 

 as broad as thorax, finely ))unctate. Occipital margin arcuate, somewhat elevated 

 narrowly, discal area of vertex deeply im])rcssed with an oblique sulcus on each 

 side of median suture extending well forward, and a very inconspicuous impres- 

 sion on each side of anterior ocellus ; anterior ocellus on median suture slightly 

 above apex of excision ; vertex on anterior margin deeply excised at median suture, 

 strongly birostrate ; antenna inserted on apex of rostrate lobes ; basal segments 

 large; flagellum very long and slender. Facial cones wanting; antennal bases 

 scarcely swollen. Labrum small, posterior ; rostrum very long, slender, acute. 

 Genae slightly swollen. Eyes large. 



Thorax scarcely arched, not very broad, quite coarsely punctate. Pronotum 

 relatively long, flat on dorsal surface, extending well down laterally; propleurites 

 long; pleural suture oblique, not as long visibly as episternum; epimeron more 

 or less concealed; forecoxae large, almost entirely visible. Dorsulum relatively 

 quite short, broad, not as long as scutum. Post-tibial spur conspicuous but 

 smaller than in C. gigantea. Wings rather small, hyaline, almost three times as 

 long as broad, broadest across second f ureal ; quite acute at apex ; first marginal
