IGO [December, 



This species is allied to D. radlia, Dist., from whicli it is struc- 

 turally differentiated by the very much shorter abdomeu, and by the 

 broadly rounded apices of the opercula.

Cosmoscarta Jicno, n. sp. 



Black, shining ; abdomen above, rostrum, legs, a few scattered spots on abdomen 

 beneath, and anal appendage, red ; apex of rostrum and femora, excepting bases and 

 apices, piceous ; ocelli large and 'bright shining yellow; eyes dull ochraceous ; 

 reticulations on apical third of tegmina distinctly pale and shining brownish. 

 Wings smoky-hyaline. Pronotum thickly and finely punctate, the lateral angles 

 broadly and sub-acutely ampliated, the lateral margin broadly ampliated and re- 

 flexed, the posterior margin truncated at base of scutellum. Tegmina very finely 

 and thickly punctate, the costal margin at base, suddenly and broadly dilated, 

 rounded, and sub-erect, the apical reticulations strongly defined. Legs setose ; 

 posterior tibiae with a strong sub-apical spine on outer margins. 



Length, 17 mm. Exp., 50 mm. Exp. of angles of pronotum, 10 mm.

This species is allied to C. viridnns, Guar., from which it differs 

 by the more strongly dilated pronotum, the tegmina with the costal 

 margin suddenly ampliated, arched and sub-erect at base, the reticu- 

 lations of the tegmina not concolorous, the different colour of the 

 abdomen, &c. The tegmina, though shining, are less brilliantly so 

 than in Gruerin's species.

Coleoptera, Sfc, at Ventnor. — During a short stay at Yentnor at the end of last 

 April and the beginning of May, I found a few insects : the season was rather further 

 advanced than it has been for some years, but the bad weather prevented much work 

 from being done, besides spoiling the localities for the few fine days that intervened. 

 One fine warm morning I found the large stones on the beach on the west of the 

 town, under and above high water mark, covered with beetles that had come up 

 from the rotting seaweed underneath. Somalota plumbea was most abundant, ac- 

 companied by Ftenidium punctatum, Fhytosus spinifer and others ; unfortunately a 

 cold wind sprung up, and in a few minutes all were gone. On the beach I found 

 two specimens of Homalota princeps, a single specimen of Bledius atricapiJlus 

 (which also occurred at Luccombe Chine), and Bryaxis Waterhousei, besides other 

 species I have before recorded from the locality. Lithocharis maritima, which I 

 generally find in some numbers, was extremely scarce, and Trechus lapidosus was 

 represented by a single specimen. 



On and about the cliffs, at the roots of plants, several good insects were to be 

 found ; the most noticeable of these was Ceuthorhynchideus Dawsoni, this was 

 attached entirely to Plantago coronopus, and literally swarmed, some plants having 

 20 or 30 specimens at least on them : they drop immediately the plant is touched 

 and lie motionless ; owing to their minute size and the exact resemblance they bear
