Descriptions of ntw species : 



CATONIA RUBELLA, n. Sp. 



Korm and size of fusca nearly. Of a uniform brown, more or less 

 inclined to ferruginous and touched wiih sanguineous on the elytral 

 nervurcs and abdomen. Front immaculate ; apical border of the elytra 

 fuscous crossed l)y pale nervures. Length, 5-6 mm. 



Head more conical than in any of our other species. Vertex broad, 

 transverse, sloping ; produced in an obtuse rounded angle ; base sub- 

 angularly emarginate ; carinne nearly straight, forming a regular triangle, 

 but little broader than long, median carina abbreviated just before the 

 apex. Front broad, scarcely widened apically, obviously convex, carinie 

 prominent, but becoming obsolete on the tumid base ; clypeus scarcely 

 distinguished from the front, the sides narrowly laminate. When viewed 

 from the side the head is produced in a blunt cone before the eye for a 

 distance of about one-half the length of the latter, and the lateral carinae 

 of the front lie close to and are concentric with the anterior and superior 

 borders of the eye. Pronotum less than half the length of the vertex, 

 with the carin.e distinct and the hind edge deeply, angularly emarginate ; 

 mesonotal carinne parallel and distinct. Median tooth of the male genital 

 segment short, abiupt, ligulate and rounded at apex, and less than half 

 the length of the plates. 



Colour : Head, pronotum, face, chest and legs testaceous brown, the 

 eyes and tibial and tarsal spines black ; mesonotum and elytra a little 

 darker and obscurely tinged with ferruginous ; elytral nervures more or 

 less distinctly sangumeous ; apex of tiie elytra somewhat infuscated, wiih 

 the apical nervures (.iboul seven in number) whitish or bordered with 

 whitish. Wings (piite strongly infuscated, with blackish nervures. .Abdo- 

 men fuscous or black, with the genital pieces and margins of the segments 

 testaceous or sanguineous.
