and Saragus. The distinctive characters of these genera and their 

 peculiarities of habit will be found under the descriptions attached 

 to each, as far as they are known, but that unfortunately is very 

 little. The larvteseemto be quite unknown, though no doubt they are 

 chiefly, if not altogether, feeders on decaying wood, but the perfect 

 insects are found some on the ground under logs and stones, others 

 under the bark of living trees, and, as a rule, it may be said, that 

 those found on or near the ground are of the apterous genera, 

 while the winged genera are inhabitants of trees. 



I give descriptions of all the species which have not been pre- 

 viously printed in the Proceedings of this Society. 



Genus Encara, Gemminger. 



Col. Heft. VI. 1870. Syn. Encephalus^ Breme. Mon. Cossyph. 

 1, p. 23. 



Head entirely sunk in the emargination of the thorax, small, 

 square. Eyes very large, almost contiguous above, widely separated 

 beneath. Antennae shorter than the thorax, the three last joints 

 depressed, forming a small indistinct mass. Thorax strongly 

 transversal, ])arabolically arched on the sides, rather narrowly and 

 profoundly emarginate in front, imperfectly contiguous to the 

 elytra and cut almost squarely at the base, with a broad but 

 slightly projecting median lobe ; the foliaceous margin very broad 

 and flat. The elytra broadly and regularly ovate, rounded behind 

 and convex on the disk with the foliate margin broad and flat. 

 Legs long and slender ; tibiae sniooth, their spurs almost invisible. 

 Metasternum elongate. Mesosternum horizontal, forked. Pros- 

 ternal projection compressed, obtusely carinated, penetrating into 

 the emargination of the mesosternum. Body orbiculai'ly-ovate, 

 winged. 



The insects falling into this genus were placed by De Breme in 

 the genus Encephahts, under the impression (evidently a mistake), 

 that Kirby had applied that name to the species now named 

 Encara Westwoodii, Boisd. Gemminger substituted the jiresent 

 name as Encejjlialus is the name given by West wood to a genus of 

 the Staphylinidee.
