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



The sculpture is suggestive of certain Tenebrionids, as 

 Asida opaca, Say. The shape, especially the inner margin, 

 recalls the Siberian Jurassic fossil Doggeria sibirica, Hand- 

 lirsch. (The species which Handlirsch refers to Doggeria 

 are probably not congeneric, so D. sibirica is herewith 

 designated the type of the genus.) 



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



Elytra 55 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 



Fig. 4. 



Chrysomelites quadrili?ieatus, sp. n. 



parallel longitudinal strige, 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 ferruginous. 



Bartonian, Bagshot Beds, Bournemouth (Gardner). British 

 Museum, 19006, with reverse. 



The parallel striae suggest the fossil Pachycoleon woodhi 

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

 to belong to the Chrysomelidoe, but cannot be referred with 

 any assurance to a living genus. 



Carabiies peracutus } 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 strise are seen to be obscurely 

 and rather coarsely punctate.
