MR. F. P. PASCOE ON THE CXJECULIONIDJG. 



The head is unfortunately wanting in my specimen, the only 

 one I have seen ; but the insect is unmistakably an Aonyclius, 

 and such an interesting addition to the genus that I am unwilling 

 to let it remain unpublished. It is considerably broader than A. 

 Hopei, the scales on the upper parts not so closely set and 

 coarser ; the pattern also is different. It is still further removed 

 from A. lineatus. 



Ectatorhinus Adamsii. E. ( <? ) ovatus, niger, fulvo-squamosus ; 

 rostro dimidio corporis breviore, basi excepta, nigro nitido; antennis 

 nigris, funiculo sat breviusculo ; prothorace crebre rude scrobiculato, 

 in medio earinula lineari nitida instructo ; elytris confertim fortiter 

 foveatis, singulis dorso tuberculis parvis saturate fulvis quatuor, apicem 

 versus tuberculo uno, postice in declivitate tuberculo majore palli- 

 diore notatis, macula ochracea utrinque basali ornatis, humeris fulvo 

 callosis ; corpore infra rude punctato ; pedibus haud elongatis 3 

 ochraceo fulvoque annulatis. Long. 6^ lin.

 corporis paulo breviore, basi excepta, nigro nitido ; antennis nigris, 

 longiusculis, clava obovata ; prothorace rude scrobiculato, dorso ele- 

 vato, in medio fortiter carinato ; elytris subcordatis, umbrino varie- 

 gatis, striato-punctatis, interstitiis rude elevatis, tertio a sutura tuber- 

 culis tribus, quinto tuberculo uno, et pone humeros tuberculo valido 

 conico instructis ; pedibus elongatis ; femoribus nigris, concinne 

 flexuose albo annulatis ; tibiis fusco albidoque annulatis ; tarsis 

 ochraceis. Long. 5^ lin.

Lacordaire founded the genus Ectatorhinus on what I believe to 

 be a female ; the two very marked species here described are of 

 the opposite sex and agree generically with the male of U. Wat- 

 lacei, the type. Tbe first species, which I have named after 

 Arthur Adams, Esq., its discoverer, is at once distinguished from 

 the latter by the tubercles on the elytra, and is interesting from its 

 northern habitat. The second species differs from both in having 

 a strong conical tubercle on each side behind the shoulder. The 

 contiguous anterior coxae is the only really important character 

 differentiating Ectatorhinus from Mecocorynus ; in my specimens 

 I do not find the scape attaining the eye as stated by Lacordaire. 

 Of the latter genus I have five undescribed species, with habitats 

 ranging from New Guinea to Cambodia and China.
