132 ~R" SHELFORD, 



cJ, $. Testaceous. Vertex of head not covered Jjy pronotum. Pronotura 

 trapezoidal, lateral margins broadly hyaline, posteriorly truncate, exposing 

 the scutellum, disc with two minute brown dots near the posterior margin, 

 a slender castaneous line defining the inner borders of the lateral hyaline 

 margins. Tegmiua quadrate, not extending beyond the 1 s * abdominal 

 tergite, sutural margins overlapping, outer. angles rounded; 3 costals, 

 1 discoidal sector, anal vein not impressed, 2 axillaries, all the veins 

 indistinct, their course marked by castaneous dots situated serially on 

 either side of every vein. Wings absent. Meso- and metauoturn with a 

 few castaneous dots symmetrically arranged. Abdomen rufo-testaceous ; 

 supra-anal lamina (3) shortly trigonal, (?) triangular, apex notched; sub- 

 genital lamina (J) triangular, cucullate, considerably exceeding the supra- 

 anal lamina, apex deeply cleft, styles triangular, springing from the inner 

 margins of the cleft in the lamina, (?) semi-orbicular, ample. Margins of 

 abdomen of $ beneath rufo-castaneous. Cerci moderate, 8-jointed. Legs 

 moderately strongly spiiied ; front femora with a row of piliform setae on 

 the anterior margin beneath; mid- and hind-femora with 4 5 spines on 

 both margins beneath. 



Total length (<?) 7 mm., (?)7.5 mm. ; length of teginiua 3 mm. ; pronotum 

 2.5 mm. X 3.2 mm. 



The ootheca is chitinous and carried with the suture uppermost. 

 (Several examples of both sexes.)

Remarks. 1 <J and 1 9 from the first of the above localities were found 

 in the nest of a spider of the genus Phryganoporus; this symbiotic associ- 

 ation is very remarkable ; these specimens are more heavily marked than 

 the rest. The systematic position of this species is a little doubtful, for 

 it presents great similarity to some species of Hololampra (Ectobiinae) ; 

 the differences separating the two subfamilies Ectobiinae and Phyllodromiinae 

 are very slight and elusive but for the present at any rate I think that 

 Hololampra should be limited^ to those small species of Blattidae with 

 reduced tegmina, with the supra-anal lamina transverse in both sexes and 

 with the mid- and hind-femora very sparsely armed *). The species 

 T. ectobioides mihi and T. af finis mihi from E. Africa present many features 

 of resemblance to this Australian species. 



1) The inclusion of T. platysoma in the genus Ceratinoptera by me (Gen. Insect. 

 Blattidae, Phyllodromiinae, Fast-, 73) is due to a slip.
