112 COLEOPTERA. 



168. CoRYLOPHUs suBLiEviPENNis, Diival, Gen., ii, 234, 



PI. 56, fig. 281 ; D. Sharp, Ent. Mo. Mag., v, 197. 



Taken in the autumn of 1868 by Mr. Crotch and 

 Dr. Sharp, under flood refuse, near Weymouth. 



It differs from C. cassiduides in its lighter colour, shorter 

 form, and less close punctuation, which is proportionately 

 much finer (in fact, scarcely visible) on the elytra. The 

 elytra, moreover, are less distinctly contracted behind. 



169. Clambus coccinelloides, Stephens, 111. Brit. Ent., 



ii ; Gemm. & v. H., 1. c. ; E. C. Rye, 1. c, 250. 



170. Clambus nitidus, Steph., 1. c, v. 



171. Ptilium minutum, Stephens, 1. c, iii, 61. 



This and the two pieceding, not being accounted for in 

 the synonymy of Wat. Cat., are given by Gemminger and 

 V. H. as good species. 



Mr. Matthews informs me the Ptiliuvi is quite untenable. 



172. Aridius nodulosus, Motschulsky, Bull. Soc. Nat. 



Mosc, xxxix (1866), part 2, 261, Tab. vi, fig. 7 ; 



Dallas, Record of Zool. Lit., iv, 1867, Pt. 2, p. 246; 



E. C. Rye, 1. c, 197. 

 M. Motschulsky describes this species from England and 

 New Holland at p. 260 of his " Enumeration des especes 

 de Coleopteres rapportees de ses voyages " (5th Article ; 

 Lathridiens\ and at p. 261 refers it to England only. He 

 characterizes several new genera near Lathridius {e.g., Per- 

 midlus, IsidiiiSy &c.\ and amongst them Aridius, which, of 

 our species, includes the present insect and L. 7wdifer, 

 carmatus, elo7igatus and ruficollis. He places A. nodulosus, 

 associated only with nod'ifer, in his section of the genus in
