Genera and Species of Coleoptera. 99 



small ; anterior coxae transverse, scarcely approximate ; tibise bicalca- 

 rate ; tarsi five-jointed, slender, short, hairy beneath. 



If rightly referred to the Cucujidae, the position of this genus will 

 be near Silvanus, which it approaches in habit and in its clavato 

 antennae. 



Rhyssopera areolata. (PI. YII. fig. 4.) 



R. fusca, sparse flavo-pubescens ; prothoracis basi latiuscula; elytris 

 areolatis. 



Hub. Tasmania. 



Opake lmlber-bro^'^^l, with a sparse yellowish or almost golden pubes- 

 cence, especially on the head and prothorax, the latter about as broad 

 as long, rounded at the side, produced into a short acute angle ante- 

 riorly and slightly contracted behind, with foxu* tubercles on its disc ; 

 scutelliun transverse ; elytra with their external margins serrated, each 

 with three rows of coarsely punctiu-ed hexagonal nearly equal ceUs, the 

 walls of which are foimed by nan'ow raised lines j labnmi, palpi, and 

 legs ferruginous. Length 4 lines. 



Bhyssopera illota. (PI. VII. fig. 4, trophi only.) 



R. fusca, sparse griseo-pubescens ; prothorace longiore, basi angiistata ; 

 elytris subareolatis. 



Hah. Australia (INielbourne). 



Like the last, but the prothorax is longer and much nan'ower poste- 

 riorly, the lines bounding the areolae and punctiu-es less marked, and 

 the pubescence of a gTeyer hue. 



Gl(eania [Trogositidae]. 



Head small, roimded and dilated below the eyes, emarginate in front. 

 The labrum entire. Antennae short, eleven-jointed, the last three form- 

 ing a subunUateral, compressed club. Eyes round, prominent. Mandi- 

 bles entire at the apex, toothed in the middle. Palpi robust, with the 

 tenninal joint subcylindrical ; maxillary lobes finely toothed, the inner 

 narrow. Labium quadi'ate, slightly fi'inged. Mentiun large, quadrate. 

 Prothorax subquadrate, narrower anteriorly, broadly sulcated at the 

 side, and slightly margined. Elytra scarcely broader than the pro- 

 thorax, subdepressed, the sides nearly parallel. AU the coxae distant ; 

 femora broad, compressed ; tibiae dilated below, terminating in a series 

 of small teeth; tarsi slender, slightly ciliated beneath, the basal joint 

 minute, the second as long or longer than the third and fourth together ; 

 claws toothed at the base. Pi'osternum roimded behind ; mesostemum 

 depressed. • 



The Trogositidae do not appear to have any very definite characters, 

 if we except the minuteness of the first tarsal joint, and include 

 genera varjring very much in their form. Of the fom' subfamilies
