without an examination of the type, that it was in reality the $ of a 

 form allied to Goetymes pictipes Blackb. A comparison of these types 

 convinces me that such is indeed the case. The differences between 

 the two forms are such, however, that it does not seem justifiable to 

 assume them to be sexes of the same species, as is probably the case 

 with Sitarida hopei White ( $ ) and Goetymes fulvicornls Pasc. ( d ) 

 (c/! Wellman, loc. cit.), though it may well be that this is indeed their 

 relationship. 



In view of our very incomplete knowledge of the species of this 

 group it seems inadvisable as yet to separate Sitarida White (1846), 

 type, 2, hopei White (= Goetymes Pasc, type, <S .tfidvicornis Pasc.) 

 from JVeph7'ites Shuck. (1837), t}^e, 5, nitidus Shuck. (= Sitarida 

 minor Champ.); the latter therefore has priority as the name of the 

 genus. 



Shuckard considered his genvxs as occupying a position intermediate 

 between the Melo'id genus Sitaris and Rliipiphorus, though placing it 

 nearer the latter. This resemblance is purely superficial ; all details of 

 structure demonstrate unquestionably its alliance to Sitaris. The simple 

 claws, toothed at the base, is a character unusvial in the Meloidae, but 

 claws of this tj^pe are found in the genus Ilornia and in Mylabris 

 tijlensis and its allies. 



The type oi Sitarida minor has been most kindly presented by 

 Mr. Champion to the British Museum. It is not known whether that 

 of Shuckard has been preserved.

ON A NEW GROUP OF STAPHYLINIDAE. 

 BY MALCOLM CAMEROX, M.B., E.X., F.E.S. 



Arpediopsixi, n. 



Antennae ll-jointed, inserted below a prominence antero-latevally, external 

 to the outer margin of the mandible. Maxillary palpi 4-jointed ; labial palpi 

 3-jointed. Ocelli wanting. Prothorax entirely corneous in front of the anterior 

 coxae, prothoracic epiniera large, the stigmata concealed ; anterior coxal cavities 

 open behind. Anterior coxae conical, promiuent j posterior coxae transverse ; 

 trochanters small, simple. Abdomen bordered, tirst ventral sediment distinctly 

 keeled in the middle line. All the tarsi 4-jointed. 



This group is related to the Omaliini, Piestini, and Oxytelini, 

 probably most closely to the first.
