258 On new Genera and Species of Lomjicorn Coleoptera. 



on eacli side anteriorly, which is covered over by tlie fringe 

 of fulvous hairs attached to the hind margin of the first 

 segment. The anterior tibias of the male are strongly bent 

 inwards from about the middle of their length, and each bears 

 a spine on the iimer side between the middle and apex ; the 

 tibise of the middle pair are strongly bent inwards towards 

 their a])ex, and each has a strong sharp spine placed on the 

 iimer side of this somewhat thickened apical portion. The 

 trochanters of the middle pair are also produced into a small 

 spine at their extremities. 



This species has a great resemblance t') Niphona cylin- 

 <7/-acfa, White ; but the latter is more strongly toothed on 

 the side of the prothorax, its middle tibiaj in the male are not 

 bent in strongly at the apex, and are not spined, nor are tlie 

 trochanters of the same pair spinose at their extremities ; the 

 lateral processes of the last ventral segment of the male are 

 also shorter, and in those examples that I have seen are not 

 curved downwards towards the middle line. 



Alidus, gen. nov. {Ntphonidcv). 



Prothorax angulate or feebly tuberculate at the middle of 

 each side. Mesonotum without stridulating surface, but with 

 a smooth polished line along the middle. Prosternal and 

 mesosternal processes with their opposed faces subvertical, 

 both processes transversely rugulose and longitudinally cana- 

 liculate ; the horizontal face of the prosternal process some- 

 what dilated ])osteriorly to fit into corresponding de])ressious 

 on the sides of the coxre. Eyes rather small, subdivided. 

 Antennae of the male nearly one half longer than tlie body ; 

 those of the female about equal in length to the body ; first 

 and third joints subequal in length, the fifth longer and 

 slightly curved, each of the succeeding joints, the eleventh 

 excepted, subequal to or slightly shorter than the third. 



Q'his genus may be recognized by the ratlier exceptional 

 character, for this group, which it possesses in having the 

 sides of the prothorax tuberculate in the middle. 



AUdus h'plagiatusj sp. n. 

 Dilute fuscus, maculis punctisque flavo-albidis sparsim aspersis, 



prothoracis dorse plaga ovali fusco-velutina utriuque ornato. 

 Long. 23-25, lat. 9-11 millim. 



Hah. China {J. G. Boioring) and Assam [Atkinson). 



Dark brown, with darker brown points and numerous 

 minute scattered yellowish-white points and spots, the most 

 conspicuous of which are a spot on the base of the fourth 

 antennal joint, a small patch on the middle of each tibia, and 

 a few spotis forming a narrow zigzag band between the middle 

 and posterior thirds of each elytron. Prothorax with a large
