second segments very long, fused together ; legs slender but posterior 

 femora straight and much thickened, spinose beneath; wings slender; 

 auxiliary veins rudimentary, more or less fused with first; latter short, 

 entering costa before middle of wing; third and fourth veins parallel; 

 discal cell complete; basal cells well developed; anal cell rounded api- 

 cally. 



According to the figure of Gobrya simulans de Meij. (Tidj. 

 V. Ent. liv. 363, 1911) this genus seems similar but is very 

 distinct. The generic characters of Gobrya given by de Mei- 

 jere are not as definite as they should be. but if one may be 

 guided by the figure given, the position of the fore coxae will 

 at once eliminate the possibility of synonymy. 



Syringogaster rufa n. sp. (Plate XIX, Figures 5-0). 



Entirely rufous or yellowish; all bristles black and hairs yellow. 

 Front semiopake with two longitudinal dark stripes above, not well

 tain aspects, silvery. Mesonotum subopake, faintly dusted with brown, 

 posterior part, especially laterally, blackish ; a black dot in depressions 

 above humeri ; scutellum subopake, yellow ; pleurae polished ; hypo-

 Anterior coxae, trochanter, bases of middle and hind femora, pale, 

 translucent yellow, nearly white ; fore tibiae and all tarsi yellow ; hind 

 femora with more or less diffused black basal ring. Wings brownish 

 hyaline, with yellow veins; a transverse fuscous band over apices of 

 second basal and anal cells, a fuscous cloud over anterior cross vein, 

 and a fuscous band over posterior cross-vein extending to costa (fig. 

 6.). 



Front less than a third the width of head. Antennae less than half 

 as long as face. First and second abdominal segments gradually wid- 

 ening apically; third segment about one-sixth to one-eighth as long 

 as first and second together, fourth to fifth or sixth diminishing in 

 length and width. Lateral series of flexor spines on posterior femur 

 confined to the apical two-thirds. Fifth and sixth veins attaining
