258 THE CANADIAN ENTOMOLOGIST 



the extreme sides of the front ; in Pyc7ioplectus there are two much larger, 

 widely-separated fovese, connected by a large and deep narrowly-parabolic 

 sulcus, giving a habitus not remotely resembUng that of Ejiplectiis. ZoUiim 

 has a deep sulcus on the flanks of the elytra, proceeding from a 

 subhumeral pit not even suggested in Meiba, and the modifications of the 

 head are also different. I have no doubt at all that these three genera 

 are valid, thus leaving six genera which alone are probably synonyms or 

 subgenera; these are : Faliscus, Nicotheus (not Nicothceus as printed in the 

 work under discussion), JVisa, FytJia, Actiasies and Dalmosella, although 

 each of the last four refers to a specially-modified group, Nisa being 

 peculiar in the terminal joints of the male antennae, Pytna in having 

 carin?e on the under surface of the femora instead of the spines of typical 

 Tyrus, Dalmosella in its very much more slender and parallel form than 

 in any of the species of Afeiba, where the hind body is constantly 

 inflated, and Actiastes, differing from Actiiun in the markedly different 

 position of the cephalic fovese. These four probably represent subgenera 

 therefore. 



Oginoceriis, Raffr. 

 This genus includes some of the largest known Pselaphids and is 

 confined to the continent of Africa, where individuals of all the four or 

 five species hitherto described are exceedingly rare, being represented by 

 uniques at present. 



Ogmoceriis Raffrayi, n. sp.— Form stout, moderately convex, piceous- 

 black, subopaque, the elytra and abdomen feebly shining and very finely, 

 rather closely punctulate ; head and prothorax coarsely, very densely, 

 punctato-scabrous, the former longer than wide, oval, moderately narrowed 

 to the broad neck, where there is a tuft of dense setae at each side ; foveae 

 large but obscure ; eyes small, before the middle ; front narrowed, 

 parallel, flat, inclined upward, the median depression at apex moderate ; 

 antennae nearly as long as the entire body, the cylindric basal joint feebly 

 sigmoid, as long as the head and prothorax combined, two to eleven 

 together gradually and moderately enlarged, with straight sides, becoming 

 decidedly stout at the antennal apex, second joint as long as wide, third 

 shorter than wide, fourth a third, fifth and sixth one-half, longer than wide, 

 seventh a little less, eighth about as long as wide, its apex angulate, ninth 

 and tenth a third wider than long, the eleventh oval and as long as the 

 two preceding, all the joints herjss^te with moderate setae; prothorax wider
