6S Mr. T. D. A. Cockerell on Fossil Arthropods 



The sculpture is suggestive of certain Tenebrionids, as 

 Asida opacdy Say. Tlie shape, especially the inner margin, 

 recalls tiie Siberian Jurassic fossil Doggeria sibirica, Hand- 

 lirsch. (The species which Handliisch refers to Doggeria 

 are probably not congeneric, so J), sibirica is herewith 

 designated the type of the genus.) 



Chrysomelites quadinlitieatus, sp. n. (Fig. 4.) 



Elytra 5'5 mm. long, a little over 3 broad; subquadrate, 

 with obliquely truncate base and apex; outer margin feebly 

 convex ; surface minutely pustulose ; disc with two pairs of 



Chrysomelites quadrilineatus, sp. n. 



parallel longitudinal strise, not deeply impressed, the outer- 

 most of one pair 1 mm. distant from the outermost of the 

 other. There are no dark bands Or markings ; as preserved 

 the elytron is pale ferruginoiis. 



Bartonian, Bagshot Beds, Bournemouth ((Tarc:?ner). British 

 Museum, 19006, with reverse. 



Tiie parallel striae suggest the fossil Pachycoleon woodhi 

 (Westwood), from the Lower Piirbeck. The insect appears 

 to belong to the Ciuysoinelidoe, but cannot be referred with 

 any assurance to a living genus. 



Carabites peracutusj sp. n. (Fig. 5.) 



Elytra 11*4 mm. long, 4*3 mm. broad ; cuneate, with 

 straight inner margin, strongly convex outer margin, and 

 very acute apex ; a stria close to inner margin, and eight 

 other ones, sharp and distinct, but failing about 3'5 mm. from 

 apex ; on close examination the stria are seen to be obscurely 

 and rather coarsely punctate.
