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.

 eyes. It is still nearer £. 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.

 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.
