258 MR. F. A. HEEO^^ AND SIR G. F. HAMPSON ON THE [Nov. 3, 



ornato, interstitiis squamtdis mirmtis rufescentihus vestitis, 

 linea alho-squamosa ultra costam lateralem, humeris fortiter 

 extus prodtictis, tibiis anticis inhcs dentihus numerosis validis 

 armatis ; corpore subtiis hrunneo-vestito, abdominis medio 

 depresso, nudo. 

 Long, {rostr. excl.) 12-5 mm. 



This species is closely related to JSJ'. nodicoUis and perpastus of 

 Boheman (the former has no affinity with the species of which it 

 stands as a synonym in the Munich Catalogue, that insect, leuco- 

 gaster Party, belonging to the genus Pantomorus). The lateral 

 spines of the new form are longer than in the other two, and 

 those of the thorax are placed farther back. The thorax is pro- 

 portionally longer, and the smooth elevated spots on its disc are 

 peculiar to this species, as is the single sharply elevated discoidal 

 costa of the elytron. This costa does not quite reach either the 

 base or apex. The pinkish colour of the scales upon the disc of 

 the elytra is perhaps not constant. We have only a single male 

 specimen.
