360 STAPHTLINIDJE. [SfeJlUS. 



contracted behind ; the antennas, also, are tliinner and longer than in 

 S. latifrons, and more resemble those of S. tarsalis. L. 3-^ mm. 



A single specimen was taken by Dr. Power at Holm Bush^ Brighton, 

 on April 19th, 1863 ; as stated above, it may be a hybrid between 

 S. latifrons and S. paijanus, but it certainly appears to be quite distinct 

 from either. 



S. fornicatus, Steph. {contractus, Er.). One of the most distinct 

 of all the Steui, and at first sight appearing generically diifei-ent ; deep 

 black, shining ; head small, scarcely broader than thorax, thickly and 

 deeply punctured, with a small, not strongly raised, smooth elevation 

 between the frontal furrows, which are broad and obsolete ; antennae 

 pitchy, lighter at base, palpi blackish, with first joint testaceous ; 

 thorax as broad as long, slightly rounded at sides, subquadrate, coarsely, 

 deeply, and closely punctured ; elytra very large and inflated, twice as 

 broad as head and thorax, nearly as long as hind body, coarsely and 

 deeply punctured ; hind body much narrower than elytra, conical, strongly 

 narrowed from base to apex, very acuminate, with base of segments 

 strongly and coarsely punctured. L. 2 mm. 



Male with the seventh ventral segment angularly excised at apex, 

 sixth depressed, thickly punctured in centre, slightly sinuate on apical 

 margin, fifth emarginate, with an impression at apex, which is crescent- 

 shaped, and has the extremities of its raised margin produced on each 

 side in the form of a tooth projecting beyond the apex of the segment.

OXYPORIN-ffi. 



Only one genus is contained in this group, which is remarkable for the 

 great development of the last joint of the labial palpi, which is very 

 much dilated and crescent-shaped, giving the palpus the appearance of a 

 stalked cup-moss or fungus ; the anterior coxte are prominent and conical, 

 and the intermediate pair are very widely separated, 



OXVPORUS, Fabricius. 



This genus contains about twenty-four species, which mostly inhabit 

 temperate and cold climates ; they are found in North America, Northern 

 Asia, and Japan, and three or four species occur in Europe ; species have 

 also been described from Central America ; our single sj^ecies is a very 

 striking and handsome insect ; it lives in the gills of fungi. 



The larva of the continental Oxyporus maxillosiis is described and figured by 

 Schiotltc (Part ii., p. 118, fig. xi. 1) : it is rather short, broad, and linear, with the 

 head rather small, narrowed in front, considerably narrower than thorax ; prothorax
