Group XVI. Large, or not very small species; the 

 penultimate joints of the antennce very strongly transverse. 



(Species 108— 1] 5). 



The species herein contained constitute a tolerably 

 natural assemblage^ though there is a great diversity of 

 colour and size. The male characters of all the species 

 are well marked and unmistakeable. H. cinnamomea, 

 and hospita occur only among the burrows of Cossus lig- 

 niperda; they might naturally be separated from the 

 others as a distinct group, except that no practical advan- 

 tage would result from this. H. ohlita occurs gregariously 

 in fungi in the autumn. The other species are all rare, 

 and little is known of their habits. 



108. Homalota cinnamomea. 



Lata, brunneo-testacea, antice vix nitida, subtiliter 

 punctata; abdomine nigricante, vix punctate; thorace 

 fortiter transverse. Long. 2-2j lin. 



Mas ; a. elytrorum sutura basi evidenter carinata ele- 

 vata ; abdomine segmento 7° dorsali medio ante apicem 

 longitudinaliter elevate, apice triangulariter producto, 

 medioque obsolete incise, utrinque spino minore acuto 

 subcui'vato. 



/3. elytrorum sutura basi vix elevata ; abdomine seg- 

 mento 7° medio obsolete longitudinaliter elevate; caetera 

 ut in a. 



Aleochara cimiamomea, Grav. Micr. 88 ; H. cinnamomea, 

 Er. Gen. et Spec. Staph. 127 ; Kr. Ins. Deutsch. ii. 289; 

 Wat. Cat.; Thamiarcea cinnamomea, Th. Sk. Col. iii. 60. 



One of the largest and finest species of the genus, and 

 perhaps resembling in appearance rather a Myrmedonia 

 or an Aleochara. It is broad, and robustly formed, a little 

 narrowed both before and behind, of a cinnamon-brown 

 colour, with the abdomen black, or pitchy-black. The 

 antennae are pitchy in colour, testaceous at the base, 

 stout and rather short, increasing in thickness from the 

 third to the seventh or eighth joint; joint three consider- 

 ably longer than two, four comparatively small, nearly as 

 long as broad, five considerably broader than four, five 

 to ten strongly transverse ; eleventh joint large, pointed.
