is less heavily marked and is of a rufous hue; E. Jiavomar- 

 ginatci. Shelf., can be distinguished by its coloration. A 

 revision of the genus Einlampra is much to be desired, 

 but without a comparison of ail the types it is a matter 

 of such consummate difficulty that it has been shirked 

 by every student of the Blattidse. The species noted 

 above might well be considered typical of Kirby's genus 

 Heterolampra, but Mr. Kirby in his Synonymic Catalogue 

 of Orthoptera includes in it all the old world species of 

 Epikimpra that cannot be fitted into the genera Hcelaia 

 and Calolampra ; the result is a heterogeneous assemblage, 

 whose diagnostic generic characters are in most cases 

 merely their locality labels.

Head flavo-testaceous, with a large black patcli covering nearly the 

 whole of the front from between the eyes to the labrum, vertex 

 mottled with castaneous ; antennae broken ; eyes pale. Pronotuni 

 not covering vertex of head, its posterior margin truncate, sides 

 deflexed, smooth, shining, dark castaneous, all the margins flavo-testa- 

 ceous, spotted with castaneous. Teginina short, reaching only to the 

 middle of the penultimate segment, coriaceous, smooth and shining, 

 the venation obsolescent, the anal and axillary veins being entirely 

 absent ; serio-punctate, the punctures indicating the obsolescent vena- 

 tion ; flavo-testaceous heavily marked with castaneous, the part of the 

 right tegmen overlapped by the left castaneous, its surface reticulated. 

 Wings equalling in length the tegmina, marginal area coriaceous. 

 Supra-anal lamina not markedly bilobate, its posterior margin 

 merely notched slightly ; sub-genital lamina ample ; cerci short, 

 flavid. Legs mottled with castaneous ; front femora with three stout 

 spines on anterior margin beneath, one on posterior margin ; formula 

 of apical spines ?, {, i. 



Total length 28'5 mm. ; length of tegmina 20 mm. ; pronotum

This species, together with E. imitans, Br., and an 

 undescribed species from the Malay Peninsula, might con- 

 stitute a new sub-genus, distinguished by the reduced
