NEW SPECIES OF STAPHYLINIDiE.

malvoides could be surrounded by a ring fence excluding vialvae, and 

 even in Lbese alpine habitats the line would not have many salients. 



It is perhaps curious to observe that the appendages of vudvoides 

 are very distinct from those of the other three species, which are not 

 very dissimilar, especially in the apophyses, which are something of 

 the form in onopordi. Yet the wing patterns are very distinct in the 

 case of mclotis, one of the three, and its place is taken by vialvoides, 

 giving three species hardly distinguishable not only in general facies 

 but in much detail.

New Species of Staphylinidae from Rhodesia. 



By MALCOLM CAMERON, M.B., R.N., F.E.S. 



The species here described were collected by the late Mr. H. C. 

 Dollman. I am indebted to Mr. H. St. John Donisthorpe for the 

 privilege of examining these insects and for co-types, the types are in 

 the British Museum (Natural History), South Kensington. 



1. Sclmtogenia dolhnani n.sp. 



Ferruginous red, dull, somewhat depressed, abdomen pointed ; fore parts 

 coarsely and rugosely punctured ; first three or four joints of the antennae, mouth 

 parts and legs, reddish-testaceous. Length 3"2mm.-5mm. 



More brightly coloured than S. crenicollis Kr., with more pointed abdomen 

 and average size larger, thorax broader, more strongly impressed on the disc, the 

 antennae thicker and the elytral sculpture less coarse. 



Head transverse ; eyes large, moderately prominent, temples parallel, 

 puncturation coarse, close and rugose ; antennte stout with the first three joints 

 of about equal length, the 4th joint a little longer than broad, the 5th to the 10th 

 transverse gradually increasing in breadth, the 11th conical, about as lon.s' as the 

 two preceding together. 



Thorax twice as broad as long, the anterior border broadly emarginate, the 

 anterior angles acute, the base deeply bisinuafce, the sides moderately rounded and 

 crenulate, slightly sinuate before the posterior angles which are acute, the disc 

 broadly and deeply impressed for nearly the whole extent in the middle-, with a 

 less distinct rounded impression between this and the posterior angles, and an 

 oblique impression at the anterior border on either side ; sculpture similar to that 

 of the head. 



Elytra as long as, but narrower than, the thorax, transverse, strongly 

 emarginate internal to the posteroexternal angles, the sculpture consisting of 

 moderately coarse and close granules. 



Abdomen pointed, the bases of the first four visible segments crenulate, for 

 the rest very finely and closely punctured and pubescent throughout*
