stoutly spined all over; in M. cedipus there are only rive 

 large, stout, widely separated spines, these becoming larger 

 from the base to the apex ; in M. Rothneyi the second basal 

 abdominal segment is stoutly produced in the middle 

 towards the apex, which is not the case in M. cediptis. 



FOSSORES. 



OXYBELUS CEYLONICUS, Sp. YiOV . 



Long. 7 mm. 



Hob. Trincomali, Ceylon (Yerbury). 



Approaches nearest to 0. squamosus Sm., with which 

 it agrees best in the form of the squama ; but 0. squamosus 

 may be known from it by the hinder tibiae and tarsi being 

 yellow, while here they are black. 



Head closely punctured, covered, with short white 

 pubescence, especially above, where it assumes a fulvous 

 hue. The scape of the antennae black above, yellowish 

 beneath ; the flagellum fulvous ; its base yellowish, 

 blackish above. The clypeus projects and is thickly 

 covered with longish silvery hairs ; the mandibles yellowish 

 at the base, black at the apex, and piceous between. Thorax 

 black ; a line on the pronotum behind ; the tegulae, 

 tubercles, sides of the scutellum, and the squamae on the 

 post-scutellum yellow. Mesonotum closely punctured, the 

 punctures more widely separated towards its apex ; the 

 suture at the base of the scutellum crenulated ; the scu- 

 tellar punctures large, widely separated, more numerous at 

 the apex, where there is, in the middle, a stout projection. 

 Post scutellar squamae curved on the outer side, ending in 

 a curved triangular tooth ; the squama large, curved at 

 the base, where there is a stout longitudinal keel ; the rest 

 of it with stout striations all clearly separated ; the apex 

 roundly incised ; the ends rounded ; the segment at the 

 side of the squama is smooth except for a few striations,
