new Species of Blattide. 35 
Total length 11°5 mm. ; length of body 9 mm. ; length of 
tegmina 9°2 mm. 
Maroni, French Guiana (F. Geay, 19038); one example 
(Paris Museum). 
P. histrio, Sauss., appears to be the nearest ally of this 
species, which is well marked by the dark tegmina with one 
hyaline band. 
Genus PsrupectosB1s, Sauss. 
Pseudectobia Alluaudi, sp. nu. 
9. Rufo-testaceous. Antenne and mouth-parts testa- 
ceous. Pronotum covering vertex of head, trapezoidal ; 
anterior margin truncate, posterior margin obtusely angled, 
lateral margins pellucid, with an opaque testaceous sub- 
marginal band bordered inwardly by a rufous suffusion. 
Tegmina convex, nitid, venation of anal and discoidal fields 
obsolete; anal vein deeply impressed, arcuate, reaching 
sutural margin at a point on one half of its length; fifteen 
costals. Wings small, hyaline; radial vein bifurcated near 
its apex; twelve costal veins; ulnar vein triramose; apical 
triangle well defined, projecting beyond the anterior margin. 
Abdomen broad ; supra-anal lamina triangular; subgenital 
lamina semiorbicular, projecting slightly beyond the supra- 
anal lamina. Front femora with eleven spines along the 
anterior margin beneath; hind femora with four pairs of 
spines ; genicular spines and a pair of apical spines on each 
femur. 
Total length 10 mm. ; length of tegmina 7 mm.; pro- 
notum 3x5 mm, 
Diego Suarez, Madagascar (Allwaud, April 1896) ; one 
example (Paris Museum). 
De Saussure created this genus or subgenus for the recep- 
tion of the species Luneli, Sauss., liturifera, Stal, insularis, 
Sauss., regarding the apical triangle and branched ulnar 
vein of the wings of prime importance. As I have shown 
(Trans. Ent. Soc. London, p. 231, 1906), the presence of an 
apical triangle in the wings is a feature that appears in so 
many subfamilies of Blattide, that, taken by itself, it is of 
small value for purposes of generic distinction. I do not 
believe that litwrifera, Stal, and insularis, Sauss., are con- 
generic, and I have seen the types of both species; Luneii, 
Sauss., is congeneric with liturifera, Stal, and I do not see 
how either species can be separated from the genus Phyllo- 
dromia; insularis, Sauss., is a broad convex insect, very
