ated by a brief distance at the cephalic margin, diverging moder- 

 ately caudad ; median area between these ochraceous-buff with two 

 microscopic flecks of prouts brown caudad. Tegmina translucent, 

 tinged with cinnamon-bufi" in proximal portions and just beyond 

 discoidal vein in entire costal marginal area, from there to dis- 

 coidal vein suff'used with mummy brown, anal sulcus also broadly 

 suffused with mummy brown, this narrowing and becoming sub- 

 obsolete distad, discoidal field weakly tinged with dresden brown 

 in all but proximal portion. Wings transparent, moderately 

 heavily tinged with mummy brown; the narrow area of the en- 

 larged portions of the costal veins, which is broader than in heiiandi, 

 light ochraceous-buff. Dorsal surface of abdomen ochraceous- 

 buff, with a weak mottled suffusion of prouts brown. Cerci light 

 ochraceous-buff, the distal joints flecked with black. Ventral 

 surface and limbs light ochraceous-buff, the abdomen with weak 

 brownish suffusions and an impressed fleck of prouts brown laterad 

 on each of the larger segments. Limbs flecked with prouts brown 

 at the bases of the spines, these flecks heavy on the tibiae. 



Length of body 10.7, length of pronotum 2.3, width of pronotum 

 3, length of tegmen 11, width of tegmen 3.2 mm. 



The type is unique. 



Neoblattella berlandi new species. Plate X, figures 5, 6 and 7. 



This species, like N. eudromieUoides described on page 232 and 

 N.fasciata (Brunner) , has the tegmina distinctly bicolored 



Nearest relationship is with eudromieUoides, under which species 

 the two are compared. 



Type : d^ ; Upper basin of Amazon River, on frontier between Peru 

 and Bolivia. ■'^ (From Captain Mailles.) [Paris Museum.] 



Size medium small and form slender for the genus. Eyes promi- 

 nent, interocular space slightly more than half width between 

 antennal sockets, ocellar spots weakly indicated but flattened sur- 

 faces of these areas oblique, rounding into the intervening flattened 

 area; lateral margins of face subparallel to clypeal suture. Max- 

 illary palpi very slender and elongate, the fourth joint gradually 

 widening distad, fifth joint three-fifths as long as fourth. Pro- 

 notum moderately convex to lateral portions, showing a pair of 

 shallow but distinct latero-caudal depressions, caudal margin 

 very broadly convex, showing a very feeble tendency toward 

 an obtuse-angulation. Tegmina and wings fully developed, ex- 

 tending well beyond cereal apices. Tegmina with (9) longitudi- 

 nal discoidal sectors. Wings with clubbed distal portions of (13) 

 costal veins elongate and heavy; discoidal vein with (6) complete 

 branches; intercalated triangle distinct, width equal to one-half 



*^ We describe this species here, as it is one of the two new species in the Paris 

 Museum collection from Peru, both of which are indeed representatives of the 

 fauna of the upper Amazon drainage.
