is less heavily marked and isof a rufous hue; £. favomar- 
ginata, Shelf., can be distinguished by its coloration, A 
revision of the genus Lpilampra is much to be desired, 
but without a comparison of all the types it is a matter 
of such consummate difficulty that it has been shirked 
by every student of the Blattide. 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 
Epilampra that cannot be fitted into the genera Hedaia 
and Calolampra ; the result is a heterogeneous assemblage, 
whose diagnostic generic characters are in most cases 
merely their locality labels.

whole of the front from between the eyes to the labrum, vertex 
mottled with castaneous ; antennz broken ; eyes pale. Pronotum

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

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,

This species, together with #. imitans, Br., and an 
undescribed species from the Malay Peninsula, might con-
