specialized. Antennae comparatively short, with first joint de- 

 pressed, unarmed. OcelH a])sent. Occiput with a pair of 

 auriform lobes. Pronotum with a pair of median, longitudinal 

 carinae. jMesonotum, metanotum and median segment with a 

 heavy, medio-longitudinal carina, the abdominal tergites with 

 this less decided. Tegmina and wings absent. Operculum 

 lanceolate, very elongate, concealing ovipositor valves and cerci, 

 extending beyond apex of distal tergite. Limbs short and ratiicr 

 heavy; femora and tibiae with margins supplied with numerous 

 lobes or lobules; cephalic femora strongly bowed. 



Pseudoceroys harroweri new species (Plate XV, figures 1 and 2.) 



This insect, compared with P. bigibbus (Hehn), both known 

 only from the female sex, differs in its very much smaller size, 

 more robust build, decidedly smaller lobes of the head and 

 limbs, absence of lobes on mesonotum, metanotum and sixth 

 tergite, and distinctive operculum. 



Type.— 9; Porto Bello, Panama. August 18 to 22, 1916. 

 (D. E. narrower.) [Hel^ard Collection, Type no. 8G4.] 



The following features are noted in addition to those given above and in the 

 generic description. Surface dull, weakly rugose and subtuberculate. Head 

 with a pair of small, elongate tubercles, like minute horns, between the eyes; 

 auriform lobes of occiput irregular and bluntly rounded, wider than high, 

 caudad of which are a pair of more approximate, blunt spiniform i)rocesses. 

 Pronotum very rough, paired median carinae moderately divergent caudad 

 and each raised in a large, blunt, conical iirojection at caudal margin of 

 pronotum ; a carina also indicated laterad on the roughened sides. Mesonot um 

 rough, with medio-longitudinal carina heavy, armed with three, heavy, blunt, 

 conical projections. Metanotum and median segment similar but lacking the 

 projections. Abdominal tergites to sixth rough and unspecialized, sixth 

 flattened and irregularly weakly concave on each side with a dark velvety 

 patch proximad. Sixth, seventh and eighth tergites with medio-longitudinal 

 carina horizontally minutely bilobate caudad on each side. Ninth tergite 

 strongly declivent produced in two small rounded projections at the base of 

 the small supra-anal plate, the latter with margins evenly and weakly convex- 

 convergent to the bluntly rounded apex, ^'entral surface rough, the pleura 

 tuberculate. Operculum with surface not as rough, longitudinally tricarinate 

 proximad but without lateral carinae distad, in that portion with lateral 

 margins very feebly convex-convergent to the rather sharply rounded apex. 

 Cephalic femora with dor.so-internal and ventro-external margins (the latter 

 only distad) supplied with a few very small, stout lobes; other femora with 

 all margins and all tibiae with dorsal margins supplied with a number ol 

 slightly larger lobes, except the ventral margins of the caudal f(>inora, wliicii 

 have the.se only distad.
