BLATTIDS FKii.M JAVA AND NORTHERN VUSTRALIA 



sigmoid, with 3 short complète branches, 2 very short rudimentary 

 branches and several short transverse vennles in that région; 

 apical triangle strongly developed. Cerei testaceous above, 

 fuscous below. Body below fusco-testaceous. Sub-genital lamina 

 very small, triangular, with two minute styles near the apex. 

 Legs testaceous, front femora armed after type B. 



Total length 9 mm. 

 I have placed this species under Sigmoidella Hebard \ though 

 the ulnar vein of its wings is only slightly sinuate. Otherwise it 

 agrées with that genus by the armature of the front femora after 

 type B, by the radial vein of tegmina and wings being simple, 

 and by the ulnar vein of the wings having rudimentary incomplète 

 branches in addition to the complète branches. By the markings 

 of the pronotum it is near to S. (Blatta) adversa Saussure and 

 Zehntner. However, the latter is a very much larger species, 

 measuring about 17 mm. in total length. 



Parajacobsonina n. g. 



This genus cornes near J aeobsonitta Hebard, 2 agreeing with it 

 (1) by the Iront femora being armed after type B and distally 

 bearing .'! heavy spines, (2) by the sides of the face converging 

 ventrally, and (3) by the radial vein of the tegmina being forked, 

 whilst that of the wings is simple; it difîers from it (1) by the pré- 

 sence of styles, (2) by the ulnar vein of the wings being simple, and 

 (3) by the discoidal seetors of the tegmina being oblique, instead 

 of longitudinal.

1 c?. Burnside, N. T. 22. IV. 1932. 



o- Head slightly free, shining black; lower part of clypeus, 

 labrum, palps and antennae testaceous; inter-ocular distance 



1 Proc, Axad. Nat. Sci., Philadelphia, vol. LXXXI (1929), p. 55. - 

 Hebard, in defining Sigmoidella, speaks of the "strongly sinuate discoidal 

 vein ut the wings", where, no douht, the ulnar vein is meant. Compare Inc. rit.. 

 p. 39. 



- Hebard, loc. cit., p. 56. The définition of this genus contains an obvious 

 slip: where the author speaks of the « forked discoidal vein of the wings », no 

 doubt, the tegmina are meant. Compare the key on p. 39. — Also the spelling 

 " Jacobsonia" , on p. 57. should he correct ed to " Jucolisiininn" . Sec pp. 

 and 56.
