Mr. F. P. Pascoe on new Genera of Cerambycidse. 307 



Darjiling. This species is a typical Diplommatina, with strong 

 costulation and a well- developed columellar tooth. 



The animal is sketched as it appears just emerging from the 

 shell. The eyes, as will be seen, are distinctly lateral, as in 

 Cyclophoims. I can trace no difference between the animal of 

 this form and that of the smooth or spirally ribbed species of 

 the Indian peninsula, which are by Pfeiffer classed as Arinia, in 

 the neighbourhood of Pupina, in a different family, and even a 

 distinct suborder from their nearest allies the typical Diplom- 

 matime. 



Central India, Feb. 1867. 



XLV. — Characters of some new Genera of the Coleopterous Family 

 Cerambycidse. By Francis P. Pascoe, F.L.S., F.Z.S. &c. 



The eighth volume of the great work of Prof. Lacordaire being 

 nearly ready for the press, I am desirous of publishing the fol- 

 lowing descriptions of some new genera of the family to which 

 that volume will be, with the Prionidse, entirely devoted, in order 

 that they may take their place in that work, the plan of the 

 author not permitting him to notice any genera which have not 

 been published. These genera do not include several new forms 

 discovered by Mr. Wallace in the Malayan Isles, which must 

 unavoidably stand over for the ' Longicornia Malayana ' publish- 

 ing by the Entomological Society. 



Chorothyse. 



( $ ). Antenna breviusculse, 1 2-artieulat8e, scapo perbrevi. 

 Elytra abbreviata, intra excavata. 

 TibicB posticae elongatse, eurvatse, compressae. 

 Abdomen breve, segmentis duobus basalibus multo majoribus. 



Head exserted, transverse anteriorly ; clypeus broadly emar- 

 ginate. Eyes large, reniform. Antennae rather short, 12-jointed, 

 a little thickish, distant at the base ; scape very short, obconic ; 

 the third joint twice as long, the following gradually shorter, 

 the last smaller and ovate. Palpi short, cylindrical. Prothorax 

 transverse, broader than the head, rounded at the sides. Elytra 

 short, hollowed out along the sutural margin, rounded at the 

 apices. Legs unequal, anterior and intermediate short ; poste- 

 rior tibia3 elongate, curved, and compressed ; tarsi short, narrow. 

 Anterior coxae exserted, contiguous. Pro- and mesosterna very 

 narrow. Abdomen short, the two basal segments much larger 

 than the rest, the second and following excavated, the excavation 

 filled with hairs.
