the rest of their sculpture fine but ill-defined. Hind-body minutely 

 sculptured. 



Remarkable on account of the very short wing-cases. 



Length, 1^ lines ; breadth, quite J- line.

1851. O. sagoloide, n.s. (Sharp ; Trans. Roy. Dub. Soc., 1886, 

 p. 381.) Hand latum, anterius angustior, rufo-testaceuni, capite 

 thoraceque fuscescentibus, minus breviter pubescente ; capite tho- 

 raceque insequalibus, profundius impressis, hoc minus fortiter trans- 

 verso, prosterius fortiter constricto ; elytris minus punctatis, basi 

 inaequale. 



Long., 2|mm. 



Antenna longer than head and thorax, strongly pubescent ; joints 

 6-10 evidently broader than those preceding ; penultimate slightly 

 transverse. Head with the two frontal impressions deep and large. 

 Thorax rather coarsely punctured, with two very deep impressions 

 on the middle, and another at each side. Elytra about twice as 

 long as the thorax, rather sparingly punctate, the punctures towards 

 the apex obsolete, shining, strongly pubescent, with a transverse 

 depression near the base, giving rise to the appearance of a slight 

 callosity on each side of the scutellum. 



This species is remarkable from its great resemblance to the 

 more elongate of the species of the genus Sagola. It is allied to 

 0. hirtellum, Fauv. in litt., but is readily distinguished by the more 

 elongate form, less transverse thorax, and more uneven surface of 

 the head and thorax. 



Picton. Helms. 



1852. O. actobium, u.s. Variegate, head and thorax black, 

 elytra castaneous, hind-body blackish, but with the two terminal 

 segments more or less castaneous, legs testaceous, tarsi and palpi 

 fulvescent ; the five basal joints of antennas reddish, remaining ones 

 opaque, dark smoky-brown. 



Head narrower than thorax, subopaque, minutely and densely 

 sculptured, and with numerous distinct but not large punctures, 

 nearly smooth along the middle, the occipital fovese well marked. 

 Antennas with the six terminal joints distinctly broader than the 

 preceding ones, tenth joint transversely quadrate, third obviously 

 longer than fourth. Thorax broader than long, base truncate, rest- 

 ing on elytra, narrower than they are ; sides finely margined, much 

 rounded, narrowed but nearly straight behind; posterior angles 

 rectangular, not acute, anterior somewhat depressed and rounded ; 

 there are three almost smooth, narrow, longitudinal areas, con- 

 fluent in front, the two intervening spaces a little depressed, and, 

 like the rest of the surface, opaque, with the same sort of sculpture 

 as the head ; the pubescence scanty, mostly dark-grey. Scutellum
