166 Mr. H. W. Bates on Longicorn 



are found beyond it; and only seven, out of the 129 

 Chon tales genera, are found in the Old World. 



Thus, two general facts of much interest, I think, are 

 elicited by an analysis of Mr. Belt^s collection of Longi- 

 comia, and there are abundant indications that other 

 tribes of Coleoptera will, on examination, confirm them ; 

 these are, (1), the homogeneity of type of the insect fauna 

 of the forest region of Tropical America, over probably 

 forty-five degrees of latitude, with great local speciality ; 

 and (2) , the existence of a distinct northern element whose 

 metropolis is Central America. These results, I am 

 strongly inclined to think, will not be invalidated by any 

 increase of knowledge respecting the Insect Faunas of 

 Tropical America. 



Fam. PRIONID^. 



Parandra grandis, Thomson, Mus. Sciefltif. p. 790. 

 — Found also in New Granada. 



Parandra imnctata, White, Cat. Loj;ig. Brit. Mus. p. 2.

Parandra searitoides, Thoms. Mus, Scientif. p. 82. — Also

BraderocJms •longicornis, n. sp. — S Elongatus, angus- 

 tatus, parallelopipedus, castaneo-fuscns, antennis corpor© 

 longioribus ; thorace valde transverse, brevissimo, utrin- 

 que spinis longis tribus subaequalibus, supra minus grosse 

 punctate - rugoso, fulvo - pubescenti ; elytris medio vix 

 latioribus, apice late rotundato, angulo suturali oblique 

 spinoso, supra leevibus sericeo-nitentibus, humeris sca- 

 brosis, disco leviter tricostato ; subtus sternis omnibus 

 coxisque fulvo-pilosis. 



Long. 1 unc. 11 lin. ; lat. elytr. medio 6| lin. 



Distinguished from Br. sulcicornis (Lee.) and Agyleus 

 (Buq.) inter alia, by the length of the antennae which, 

 in the S , exceed by one sixth the length of the body. 

 As in both these species, the tibise are without spines, 

 the femora scabrous, and the third antennal joint sulcate. 



One example in Mr. Belt's collection. The Derobra- 

 chince are especially characteristic of the northern part of 

 Tropical America; all the species, eight in number, 

 inhabiting the region between New Granada and the
