eyes and the moutli-parts rufo-testaceous. Eyes rather wide apart. 

 Antennae piceous. Pronotiim as in peltata, butdiscoidal lyrate mark- 

 ing larger. Tegmina suffused with castaneous, not extending beyond 

 apex of abdomen. Wings much reduced, coriaceous, veins thickened, 

 ulnar vein with 12 rami, vena dividens giving off transverse venules, 

 posterior part of wing not folding in fan-like manner. Abdomen 

 testaceous, mottled with fuscous, supra-anal lamina quadrate, apex 

 slightly emarginate. Cerci very short, sub-genital lamina semi- 

 orbicular, ample. Coxae testaceous, legs castaneous, posteriort arsi 

 as in P. 'peltata. 



Length 23 mm. ; length of tegmina 19 mm. ; length of wings 

 10 mm. ; pronotum 8 mm. x ir2 mm.

\n P. peltata, Karsch, the wings are reduced to minute 

 corneous scales from which the venation has disappeared, 

 these scales represent only the anterior parts of the 

 wings ; semialata in its wing-structure is a connecting 

 link between Pseudogyna and 'peltida. 



The genus Gynopcltis, Gerst. (sub.-fam. Perisphaeriinae) 

 in the male sex is very like Gyna, Br., but may be dis- 

 tinguished by the shortly produced, trigonal supra-anal 

 lamina, exceeded by the sub-genital lamina and by a 

 hooked lappet, which is the left posterior angle of the 8tli 

 abdominal sternite, projecting from beneath the 7th 

 abdominal sternite on the left side ; there is only one style 

 and this is minute. In G. cryptospilo, Wlk. \_=^iyicta, Gerst.] 

 the front femora have four or five spines on the anterior 

 margin beneath. The females of the genus are entirely 

 apterous. 



The following species appears to be new : — 



Gynopeltis neavei, sp. n. (PI. IX, fig. 39.) 



(J Testaceous ; head with vertex and an irregular band between 

 the ocelli castaneous. Eyes '75 mm. apart ; antennae piceous. Pro- 

 notum with a lyrate piceous marking on the disc as in the genus 

 Gyna. Tegmina testaceous, rather narrow, outer margin sinuate, a 

 line at base of mediastinal vein and the anal vein piceous, disc 

 indistinctly suffused with castaneous, the part of the right tegmen 

 overlapped by the left, castaneous. Wings with anterior part 

 suffused with flavid, ulnar vein with 12 rami, 7 being incomplete. 

 Abdomen above rufo-testaceous, beneath testaceous. Cerci rather
