170 Mr. D. G. Ilutherfovd on neio Goliath beetle, §■<?. 



l^Note, by H. W. Bates. — Mr. Eutherford having 

 left England for West Africa before the above description 

 was printed, and therefore without having an opportunity 

 of supplementing it, I venture to do this for him, having 

 been entrusted by Mr. Horniman with the type and also a 

 specimen of the ? , received afterwards from the same 

 locality, for examination. 1. The $ specimen appears to 

 me imperfect with regard to the armature of the back part 

 of the crown, where in C. Sayi there is a quadrangular, 

 nearly horizontal plate, dentiform at its anterior angles. 

 In C. Batesii the whole upper surface of the head is 

 deeply concave, but the hind part of the crown (which 

 limits the concavity) shows a fracture in its middle, making 

 it probable that there should be a horn or spine here, 

 similar in position to that of C. Nireus. 2. The affinity 

 with C. Sayi relates only to the shape of the forked horn 

 and the produced incurved angles of the clypeus, to the 

 short sternal process, and the spined outer edge of the 

 four hind tibias in the $ . In most other essential points 

 of structure the two insects are very different. The chief 

 points are the remarkably short and simple anterior tibite 

 in the $ , which resemble those of C. aurata and quadri- 

 maculata, but are still shorter and more dilated, owing to 

 the much-compressed ridge along their outer edge. In 

 C. Sayi the tibias are elongate, slender, and trispinose on 

 their outer edge. The black velvety pile of C. Batesii is 

 composed of conspicuous but short black hairs, quite 

 different from the compact silkiness which appears like 

 part of the integument in C Sayi and Passerinii. 

 3. This combination of peculiarities renders it impossible 

 to locate the new species in any of the subgenera that 

 have been proposed for the Ceratorrliince. 4. The $ has 

 remarkably short and stout anterior legs, the tibias being 

 broad, and armed with three short and broad teeth on their 

 outer edge. The clypeus is much shorter and more 

 rounded than in the ? of any other Ceratorrhina, and its 

 lateral and front edges are uniformly and strongly elevated, 

 rendering the surface concave. The spines on the outer 

 edge of the four hind tibias are replaced by strong and 

 broad triangvilar teeth.]
