apart as those of B. gigantea ; tlie intervening space witli a longitudinal 

 farrow. Proihorax extending sonievvbat beyond the head, testaceous, 

 dilated and letuse ahmg each side and in front, much rounded in front, 

 slightly angular on eacli side in front of llie huuieris, along which it is 

 slightly truncated; a large ramose luteous patch on each side near the 

 hind border; fore part wiili slight irregniar ramose ridges; space above 

 tiie head somewhat arched; hind border hardly angular in the middle. 

 Mesothorax and metathovax biown, the former with a little oblique tes- 

 taceous streak on each side near the middle. Abdomen brown ; subanal 

 lamina with two distinct lobes, which are anj^ular on the inner side of the 

 hind border. Legs short, stout; trochanters testaceous ; tarsi shorter and 

 stouter than in the normal species of the genus, tawny beneath. Fore 

 wings mostly coriaceous; transverse sectors comparatively few and irregular ; 

 secondary veins distinct. Hind wings blackish and with transverse sectors 

 like those of the fore wings in front of the discoidal furrow; hind part 

 blackish cinereous, with fewer and more regular transverse sectors. Length 

 of the body 23 lines ; of the wings 45 lines. 



This species differs widely from all the BlabercB jireviously recorded. 

 It somewhat resembles B. Atropos in colour, but differs much from it in 

 its structure, which approaches that of Monavliodia, 



a. Brazil. From Mr. Stevens' collection. 



16. Blabera rUSIFOEMIS. 

 Mas. Fulva, fusiforinii ; caput, pectn.t, nhdompn et prdes nigra; prn- 

 tliorax niger, fere elliplicus, fulvo late marginnlus, margine antico 

 subarcualo, lateribus rolundalis apud Immeros svhsinualis ; alee 

 abdomen longe superantcs ; anticce coriacce, sat angustce, apice ro- 

 tundatcE, vitla basalt brevi nigricanle apice diffusa, area discoidali 

 membranacea ; poslicce obscure cinerece, venis mgricanlibus. 



Male. Tawny, fusiform. Head and its appendages, pectus, abdomen 

 and legs black. Piotborax black, nearly elliptical, with a broad tawny 

 border; lyre-shaped mark distinct ; lore part vaulted in the middle, slightly 

 concave on each side ; fore border slightly arched ; sides rounded, slightly 

 sinuaied along the humeri; hind border nearly straight. Wings long, 

 extending much beyond the abdomen. Fore wings rather narrow, coria- 

 ceous, rounded at the tips; a blackish stripe extending from the base along 

 the humeral vein, widened and diffuse in the disk ; discoidal area mem- 

 branous ; discoidal sectors numerous, regular. Hind wings dark cinereous ; 

 veins blackish. Length of the body 24 lines ; of the fore wings 54 lines. 



The specimen here recorded is imperfect and cannot be fully described. 

 Its narrower body distinguishes it from all the species here described, as 

 well as from B. gigantea, B. Atropos, B. Mexicana and B. marrnorea. 

 From B. Cubensis, B. Brasilio.na and B. minor it may be distinguished by 

 its longer wings. It differs from B. trupezoidea, B.ferruginea and B.fra- 

 terna by iis narrower form and by its wings, and from B. Claraziana, 

 B.fumigata and B. dubia by its larger size.
