Family JASSID^. 

 11. Idiocerus (?) punctatus, sp.n. (PI. XV, Fig. 16.) 



Long. Corp. cum tegm. 5 mm. ; long. tegm. 3'5 mm. 



Almost uniform testaceous, darkest on the thorax, which is- 

 sculptured with transverse striae. The front of the thorax is some- 

 times speckled with brown, and the hinder part and base of the 

 scutellum are marked with four rather indistinct brownish bands. 

 Ocelli in the middle of the front, about twice as far apart as each 

 is distant from the margin of the eye. Tegmina with longitudinal 

 rows of brown setiferous punctures, and with a brown spot on the 

 inner margin towards the end of the vein of the clavus. Hind 

 tibiae long, whitish, strongly ciliated. 



Five specimens: from East Coast, August, 1897; Flying Fish 

 Cove, October, 1897 ; and JN'orth Coast, January, 1898. 



Somewhat resembles Bytlwscopus testaceus, Wlk., from Sarawak, 

 but much smaller, paler, and with the ocelli much further fi'om the 

 eyes. It is still nearer B. unicolor, Wlk., from Makian (Celebes) ; 

 but the latter species has a brown spot at the end of the tegmina, 

 and the front is less rounded above. 



Order 7.— MALLOPHAGA. 



By W. F. KiEBY, F.L.S., F.E.S., etc. 



A SINGLE specimen (East Coast, September, 1897), probably from 

 some marine bird, but closely resembling, except in its much 

 greater size, Nirmus attenuatus, Nitsch, as figured by Giebel 

 (^Insecta Epizoa, Tab. vi, fig. 1). The latter species is found on 

 the corncrake.
