304 Mr. R. Shelford's Studies of the Blattidae. 



Genus 10. Temnelytra, Tepp. 



Temnelytra, Tepper, Tr. R. Soc. S. Australia, xvii, p. 38 

 (1893). 



Characters. Body flattened and depressed. Antennae longer 

 than the body. Pronotum anteriorly parabolic, posteriorly truncate, 

 exposing the large scutellum. Tegmina quadrate or sub-quadrate, 

 extending to the 1st abdominal tergite. Wings entirely absent. 1st 

 abdominal tergite {$ ) with scent-gland opening. Posterior angles of 

 distal abdominal tergites produced {T. imdidivitta, Walk., ^ is an 

 exception). Supra-anal lamina, ( (^ ) quadrate, margins entire, ( $ ) 

 triangular, apex emarginate. Cerci longer than the lamina in both 

 sexes. Posterior metatarsus very short, spined beneath. 



Type of the genus — T. truncata, Br. 



This is a well-defined genus. The obtuse angles of the 

 distal abdominal tergites in T. undulivitta, Walk. {$), is 

 paralleled in the genus Cntilia by C. scdilloti, Bol. {$), also 

 a New Zealand species. The species ahbreviata included 

 by Mr. Tepper in this genus is a true species of Temno- 

 fteryx (sub. fam. Pliyllodromiinae) ; I have seen the type, 

 which is in the Melbourne Museum. 



KEY TO THE SPECIES. 



1. Pronotum with fuscous vittse . . . T. undulimtta, Walk, 

 r. Pronotum without fuscous vittse.

Periplaneta undulivitta, Walker, Cat. Blatt. Brit. 

 Mils., p. 144 (1868). 



$ . Rufo-testaceous. A band between the eyes and two stripes 

 down the face, castaneous. Antennae rufo-testaceous. Pronotum 

 with the disc rather darker than the margins, an undulate castaneous 

 vitta on each side, extending on to the tegmina, which are quadrate, 

 their venation obsolete. Abdomen fusco-castaneous, margins and 

 two spots on each side rufo-testaceous. Posterior angles of abdominal 

 tergite not backwardly j)roduced. Supra-anal lamina quadrate, 

 posterior angles acute, posteriorly widely emarginate. Cerci very 

 short and blunt. Sub-genital lamina quadrate, styles as long as 

 cerci, lateral. Legs testaceous. 



9 . Similar, abdomen above testaceous with lateral castaneous spots
