152 COLOMBIAX DERMAPTERA AND ORTHOPTERA 



three ocelli minute, not closely crowded, forming the apices of an equilateral 

 triangle, the surface about each hardly raised, the depression before the median 

 ocellus very weak. Pronotum with surface slightly roughened. Me-sonotum 

 with surface decidedly roughened and with a few tubercles near the lateral 

 margins and laterad on the dorsum, of which latter the second pair are decided, 

 the third (caudal) pair only a little less pronounced. Tegmina reduced, short; 

 shoulders strongly compressed, moderately depressed, outline strongly convex, 

 showing no angulation; caudal margin of dorsal field oblique, weakly concave 

 to sutural margin, as a result only a vestige of the area remains in which the 

 velvety marking, so conspicuous in many species of the genus, is developed; 

 network of veins heavy. Wings reduced, extending only slightly beyond 

 apices of caudal femora. Disto-dorsal abdominal segments with a medio- 

 longitudinal keel, seventh and eighth with keel slightly raised and bluntly 

 rounded distad. Ninth dorsal abdominal segment not as broad dorsad as in 

 phthisicum, with distal margin moderately concave, leaving exposed the minute 

 supra-anal plate with margin convex. Cerci short, stout. Operculum with 

 lateral margins straight, convergent distad to the acute apex, which is situated 

 beneath the cereal bases. Cephalic femora with cephalic flexure moderately 

 decided; all femora and tibiae with four carinae conspicuous. Tarsi heavily 

 supplied with hairs on ventral surfaces, the large distal pulvilli of the four 

 proximal joints not concealed. Moderate arolia present. 



Length of body, 57; dorsal surface of head, 4.3; pronotum, 4.5; mesonotum, 

 5.7; tegmen, 6.6; wing, 31; cephalic femur, 16.3; median femur, 12.8; caudal 

 femur, 8.4 mm. Width of head, 4.1; pronotum, 3.4; mesonotum, 4.3; dorsal 

 field of tegmen, 3.6; wing, 21 mm. 



General coloration dirty blackish brown. Head mummy brown mottled. with 

 prout's brown, with a paler, buckthorn brown. Inroad postocular band. Pro- 

 notum and mesonotum mummy brown, obscurely mottled with prout's brown. 

 Lateral field of tegmina dull black, dorsal field brownish black. Wings with 

 lateral portion of anterior field brownish black, dorsal portion brownish black 

 except proximad, where it lacks heavy pigmentation and is buffy'^; posterior 

 field subtransparent, immaculate, pale ochraceous-salmon. Abdomen and ven- 

 tral surface blackish brown. Proximal half of femora tawny, distal half black. 

 Tibiae and tarsi tawny. Antennae black, except proximal half of sixth, eighth 

 and tenth joints which are ochraceous-tawny, the succeeding alternate joints 

 similarly annulate but becoming paler distad, ochraceous-tawny and buckthorn 

 brown. 



The type alone has been examined. 

 Pseudophasma eupeplum new species (Plate XXII, fig. 1.) 



This large and handsome species shows close relationship to 

 P. fulvum (Redtenbacher), differing in the shorter mesonotum, 

 distinctive tegminal and wing coloration and sharply acute 

 operculum. 



^' This is briefly visil)le beyond the tegmina when at rest, due to the eniar- 

 gination of the distal jwrtion of the tegmina.
