E. Shelford, New Blattidae. 123 



somewhat swollen; antennae and palpi fuscous. Pronotum discoidal, 

 sides deflexed, anteriorly and posteriorly truncate , posteriorly 

 niargined with piceous. Tegmina exceeding the apex of the ab- 

 domen. Wings with anterior half castaneous. Abdomen beneath 

 with disc castaneous ; snpra-anal lamina triangularly produced, 

 apex emarginate but not deeply. Cerci long, fusiform. Coxae 

 and tibial spines rufo-castaneous, front femora armed on anterior 

 niargin beneath with a complete row of spines, the distal shorter 

 than the proximal, unarmed on posterior margin. Posterior meta- 

 tarsus longer than remaining joints of tarsus, pulvilli apical. 



Total length 22,4 mm; length of body 18,9 mm; length of 

 tegmina 17,1 mm; pronotum 5,8 mm X 7 mm. 

 1 $. Cameroons. 



Genus Nauphoeta Burm. 



Nauphoeta epilamproides sp. n. (Plate II, fig. 7). 



$. Flavo-testaceous. Head with Vertex projecting considerably 

 beyond anterior margin of the pronotum. Distance apart of eyes 

 less than length of first antennal Joint, a band between the eyes 

 and a narrower band between the antennal sockets, castaneous. 

 The two apical joints of the maxillary palpi castaneous. Antennae 

 fuscous. Pronotum elliptical, its greatest width behind the middle, 

 anteriorly truncate, posteriorly very obtusely angulate, covering 

 the scutellum, uniformly flavid. Tegmina very broad , anterior 

 margin arched , posteriorly rounded , seriately punctate between 

 the veins ; marginal area ecpial to one third of total breadth, 

 mediastinal vein multiramose, radial and anal veins black ; the veins of 

 the marginal area beneath are more strongly marked and elevated. 

 Anterior part of wings coriaceous, suffused with rufo-castaneous. 

 Abdomen beneath rufo-testaceous ; supra-anal lamina produced, 

 bilobed ; sub-genital lamina short, exceeded by the supra-anal 

 lamina, notched on either side to receive the slender styles, the 

 posterior lateral angles acute, spined 1 ). Cerci moderate, fusiform. 

 Legs with the coxae and femora rufous, the genicular extremity 

 of the femora, the tibiae and the tarsi castaneous ; front femora 

 unarmed beneath, formula of apical spines y, T , \, no genicular 

 spines on front femora. 



$ Similar to $ but larger and paler, the tegmina extend 

 more beyond the apex of the abdomen ; supra-anal lamina more 

 markedly bilobed ; sub-genital lamina ample, its posterior margin 

 sinuate. 



x ) This is a character common to many species of Nauphoeta, but 

 it seems to have escaped notice hitherto.
