PROTEININ^. 



This sulj-family contains two genera, which are distinguished from the 

 Ilomaliinas, to which they hear a strong affinity, by having no ocelli on 

 the vertex of the head ; the anterior coxa? are transverse, sidjlinear, and 

 scarcely prominent, and the posterior coxoe are large and transverse ; the 

 antennae are eleven-jointed and all the tarsi five-jointed ; the species are 

 chiefly found in fungi. The genera may be distinguished as follows : — ■ 



I. Antenna) with joints 9-11 larger ; mesosteruum not 



cariuate Peoteinus, Latr. 



II. Antenna! with eleventh joint only larger; mesosteruum 



cariuate MEaAEXHRUS, Steioh. 



PROTXIZNVS, Latreille, 



This genus contains about a dozen or fifteen species, the majority of 

 which are found in Europe ; single species have, however, been described 

 from California, Alaska, Japan, and Chili ; there are four British species 

 which may be distinguished by their different size and sculpture ; mature 

 specimens may be determined by the colour of the basal joints of the 

 antennae, but in immature specimens this is a somewhat variable 

 character ; they occur chiefly in fungi, but are also found in haystack 

 refuse, &c. ; in the male the seventh ventral segment of hind body 

 is emarginate ; the tarsi are all five-jointed. 



The hirva of Proteimis hrevicolUs (ovalis) is described by Chapuis and Candeze 

 (Cat. des Larves des Coleopteres, p. G2) : it is about 4 mm. iu length, linear, sub. 

 cylindrical, slightly narrowed in front and behind, and clothed with long, scattered, 

 erect hairs; it is whitish with the head of a dirty -yellowish colour, and the thoracic 

 segments of the same shade but rather clearer; the head is narrower than the thorax, 

 and is almost quadrate ; it has three ocelli on each side ; the scutum of the prothorax 

 is the most developed ; the anal appendage is tubular and conical and used for pro- 

 gression, and the cerci have the first joint three times as long as the second ; the larva 

 is found in fungi.
