228 Ng-^y AUSTRALASIAN BLATTIDAE^ 



but whilst uncinata mihi is dark castaneous with a yellow lateral border, the pre- 

 sent species is of quite different appearance, being considerably larger, of! much 

 lighter colour, and almost concolourous. It is curious that two species should 

 differ so much in fades, whilst both of them present two almost identical and 

 very striking departures from the usual form. That the one is not an insular 

 form of the other is shown by the fact that Dr. Illing-worth has since forwarded 

 some specimens of uncinata (smaller than the Type) taken in 1919 "ex beach 

 Herbert River" about 130 miles south of Cairns; and also some taken at Gordon- 

 vale. 



Dr. Illingworth has submitted to me a considerable number of Blattidae 

 from the neighbourhood of Cairns and Gordonvale, and has kindly given me many 

 of them. Three new species of his discovering are described in the present 

 paper, and it is a pleasure to propose that this one should bear his name. 

 Cdtilia brevitaesis, n.sp. 



Nigro-eastaneous, smooth, nitid except the posterior tergites which are finely 

 shagreened. Head ruf o-castaneous ; ocelliform spots yellow; antennae pale fus- 

 cous, of about the leng-th of the body. Thoracic tergites with their posterior 

 margins slightly backwardly produced medially. Tegminal vestiges completely 

 separated from the mesonotum, articulation not completely covered by the prono- 

 tum, apex not obliquely truncate. No vestiges of wings beyond a slight back- 

 ward prolongation of the postero-lateral angles of the metanotum. Abdomen 

 with the postero-lateral angles of tergites 5, 6 and 7 backwardly produced; ter- 

 gites 6 and 7 and the supra-anal lamina faintly shagreened, lateral margins 

 entire. Supra-anal lamina of d" and of ? subtriangular, apex truncate, widely 

 emarginate, (emargination ang-ular in c?, rounded in ?,) extending to about 

 half the length of the cerci; sternites concolourous. Subgenital lamina of <? 

 subquadrate, posterior margin rounded, with a very long spine at the base of 

 each style. Leg's fusco-castaneous, posterior metatarsi about equal to the re- 

 maining tarsal segments combined, biseriately spined beneath, pulvilli" short, 

 middle metatarsi not spined beneath. 



Ootheca chitinous, castaneous, approximately twice as long as deep ; suture 

 serrate, carried uppermost; surface smooth, entirely devoid of earinae. Length, 

 <S 15—18 mm., $ 15—19 mm. 



Type, specimen No. 233 (c?) ; allotype, specimen No. 234 ($), Coll. 

 Shaw. Several c? and 2 paratypes. 



Bab. — iY. Queensland: Cairns, Gordonvale (Dr. J. F. Illingworth, 1917-1919). 



Notes. — Dr. Illingworth sent me for identification several specimens of this 

 cockroach. It closely resembles C. nitidella mihi (Mem. Qland Mus., vi., 1918, p. 

 155), but is not of so depressed a form, and its short posterior metatarsus with 

 comparatively long pulvillus at once separates it from that species. The pos- 

 terior metatarsus is definitely biseriately spined beneath, so it seems best to refer 

 brevitarsis to the genus CiMia. This segment is about the length of, or slightly 

 shorter than the remaining tarsal segments combined; its pulvillus is not apical, 

 but extends a little upwards, though not so far as in Platyeosteria. The ootheca 

 is still attached to one of the paratypes (No. 235, Coll. Shaw) and while of 

 similar proportions to that of C. nitidella (I.e., p. 157) it differs from it in being 

 not fluted, but quite smooth. Half the paratypes are in Dr. Illingworth's collec- 

 tion.
