108 Descriptive Catalogue [1897. 



Africa, but they vary considerably ; most of the Asiatic species have 

 a long, soft pubescence, and have no abdominal carinae, whilst the 

 Australian, American, and African ones as well as few Asiatic have a 

 very short, bristly pubescence, and two or three carinae on the first 

 dorsal segment of the abdomen, which impart to them a totally 

 different appearance. 



Few species are known from Africa, where they seem to be rare. 



Tmesiphorus rugicollis. 



Oblong, piceous red, elytra chestnut red, and antennae ferruginous 

 or entirely ferruginous or rufous, palpi and tarsi testaceous, body 

 covered with a pubescence having a somewhat golden tinge ; head 

 very closely rugoso-punctate, longer than broad, constricted in front 

 of the antennal tubercle, which is ampliate and deeply divided, and 

 having between the eyes two large foveae, slightly transverse ; between 

 these the vertex is carinate vertically, and raised transversely behind, 

 the infra-ocular can thus obtuse ; third joint of palpi briefly oblong, 

 angular outwardly in the middle, appendiculate, fourth broadly 

 and roundly dilated ; antennae robust, first joint large, cylindrical, 

 second quadrate, third to eighth a little smaller than the others, 

 third to seventh slightly transverse, the eighth more so, club large, 

 ninth and tenth trapezoidal, tenth a little larger and slightly trans- 

 verse, eleventh truncate at base, ovate, obtuse at tip ; prothorax 

 closely rugoso -punctate, subcordate, subgibbose, rounded laterally in 

 front, and from there sinuate on account of a large fovea situated on 

 the side, having in the median part above the base an acute tubercle 

 and an oblong, basal fovea, the bottom of which is smooth ; elytra 

 robust, sparsely punctured, subquadrate, slightly transverse, with 

 the shoulders oblique, clavate, bifoveate at base and obtusely costate 

 in the disk ; this costa is abbreviate above the apex, and the suture 

 costiform ; abdomen larger than the elytra, slightly rounded laterally, 

 somewhat convex, the two first segments tricarinate ; legs strong, 

 anterior tibiae thickened in the middle and arcuate. 



Male : Ninth joint of antennae depressed inwardly, tenth totally 

 and broadly excavate, dentate inwardly, and less so outwardly, 

 eleventh ovate, neither deeply nor broadly impressed, more or less 

 unidentate ; metasternum convex, deeply sulcate behind ; second 

 ventral segment of abdomen impressed in the middle at apex, third 

 minutely tuberculate at apex, these tubercles more or less approxi- 

 mate. Length 2-50-2-60 mm. 



Hob. Natal (Frere), Zanzibar mainland (Lindi). 



I had at first considered this species as identical with T. collar-is, 

 Raftr., and the description of the male which I gave in the ' Eevue
