Genus DYNOPSYLLA novum 



Body large, robust, pubescent. Head very deeply cleft in front 

 between antennse; vertex very deeply depressed between pos- 

 terior ocelli, with a horn-like process in front of each posterior 

 ocellus directed forward and upward; genal cones wanting; 

 frons small, elliptical. Eyes and ocelli large. Antennse very 

 long, longer than body or at least as long, slender ; basal segment 

 very elongate and large, much longer than II. Thorax broad; 

 pronotum short, much depressed below dorsulum. Legs, stout 

 and large; hind tibise unarmed at base, but with several very 

 large spines at apex. Forewings membranous, very large, pow- 

 erful, angulate at apex, veins heavy; venation atypical; hind 

 wings much smaller, frenulum conspicuous. 



Type of genus : Dynopsylla cornuta sp. nov. 



This genus belongs to the subfamily Carsidarinse, being related 

 rather closely to several genera therein, including Carsidara. 

 The absence of the basal spur on the hind tibise, I believe, is of 

 minor importance. 



Dynopsylla cornuta sp. nov. (Plate I, figs. A, E, H, I, M.) 



Length of body, 3.8 mm. ; length of f orewing, 4.9 mm. ; width 

 of head with eyes, 1.2 mm. ; length of basal segment of antennse, 

 0.5 mm. ; flagellum, 5.8 mm. General color dark reddish brown ; 

 gense, pleura, femora, tibiae, and basal half of flagellum light 

 brown ; notum with lighter stripes. Body very large and robust ; 

 head, basal antennal segment, thorax, venter of abdomen, genital 

 segment, legs, and wing veins with long pubescence. 



Head much narrower than thorax, short, relatively small, very 

 deeply cleft in front and above, with anterior ocellus in front 

 at base of cleft and posterior ocelli much elevated; vertex pro- 

 duced into a large horn-like process in front of each posterior 

 ocellus and closely behind antennal insertions. Frons small, 

 elliptical, covered by gense except around front ocellus; gense 

 very large, long, produced forward on inner margin of antennal 

 insertions; clypeus small, situated far back. Eyes large. An- 

 tennse as long as body to tip of wings, one-half longer than 

 body alone, slender; basal segment unusually long and large, 

 more than three times as long as II ; III-VI subequal in length ; 

 VII-VIII a little shorter than preceding ones ; IX-X short ; ter- 

 minal setse very short. 



Thorax large, stout, strongly arched ; pronotum short, greatly 

 depressed below dorsulum; metascutellum large, with 2 short 

 cariniform processes above for supporting the wings. Legs
