new Species of Blattidae. 3 



curved upwards and backwards. Cerei infuscated. Lega 

 testaceous; front femora with a complete row of spines on 

 anterior margin beneath. 



? . Similar, but supra-anal lamina sharply triangular, apex 

 not emarginate, surpassed by the semiorbicular, ample sub- 

 genital plate. 



Total length 11 mm.; length of body (3^) 8, (?) 7 mm.; 

 length of tegmina 8*5 mm. ; pronotum 2"5 X 3 mm. 



Queensland, Peak Downs (Godeffroy). Three specimens. 



Types in the Stockholm Museum. 



This species is transitional to the genus BlatteUa, Caud., 

 as typified by B. germanica^ L., but on account of the incom- 

 plete ramus of the vena ulnaris alarum I prefer to place it in 

 Iscknoptera. 



Mareta scripta^ sp. n. 



$ . General colour sordid testaceous. Head with a band 

 between the eyes, two lines on tlie frons, and two spots just 

 above the clypeus castaneous. Antennse pale testaceous at 

 base, remainder infuscated. Pronotum transversely elliptical, 

 lateral margins broadly hyaline, disc with castaneous dots 

 and lines arranged in a symmetrical pattern. Tegmina and 

 wings exceeding the apex of the abdomen. Tegmina with 

 all the veins bordered with quadrangular spots of pale brown ; 

 radial vein simple, 13 costals, discoidal sectors numerous, 

 oblique, posterior ulnar simple. Wings hyaline ; mediastinal 

 vein biramose ; 8 costals, the more proximal with incrassated 

 apices, the first crossing the lower mediastinal branch ; ulnar 

 vein 4- to 5-ramose ; an inconspicuous apical triangle. 

 Supra-anal lamina transverse ; subgenital lamina produced at 

 the apex into a lobe terminating in two styliforni processes, 

 the genital styles situated on either side of this lobe. Cerci 

 and legs testaceous, the former fusco-maculate towards apex. 



Total length 11 mm. ; length of body 7*5 ram.; length of 

 tegmina 9 mm. ; pronotum 2x3 mm. 



Queensland, Peak Downs {Godeffroy). Three specimens. 



Tjpe in the Stockliolm Museum. 



Owing to the structure of the subgenital lamina the male 

 looks as if it had four genital styles. Superficially the insect 

 resembles Phyllodromia ceylonica, Br. (synonyms, P.punctu- 

 laia, Br., P. nimbata, Shelf.), but the structural characters 

 of alary organs and femora establish its generic identity as 

 here given. The colouring of the tegmina, moreover, is 

 quite characteristic of Mareta.
