iu regarding them as being all the same species, that species has the 

 unusual character of extreme variableness in the striation of the 

 elytra, which in some sj)ecimens are absolutely strongly punctate-striate, 

 while in others (the majority, strange to say) the striation is all but 

 entirely effaced. I cannot, however, detect the slightest character 

 apart from this on which to found a specific separation. 



This species is rather closely allied to cordaticoUis, but differs by 

 its more elongate and less convex build, the thorax less transverse with 

 sides less strongly rounded, and almost total absence of basal fovese, 

 and the elytra quite strongly narrowed in front, with their strife always 

 distinctly (in proportion to the distinctness of the striae) punctured to 

 behind the middle. From angusticolUs it differs by its subcordate 

 thorax, from nuhicola by its much less parallel build, &c., from 

 DeverUU by its much less convexity.

 eJongato-ovalibus, profunde punctato-striatis, striis apicem versus obsoletis, humeris

One specimen, in a steam crack beside the crater Kilauea, Hawaii, 

 where I almost burned my fingers in securing it. 



Allied to B. pacijicum, mihi. Apart from difference of colour 

 and size, igiiicola is a narrower insect, with the thorax very much less 

 contracted behind. Both the Hawaiian differ from the European 

 species of Loplia in the extremely deep sculpture of their elytra, the 

 punctate strife of which hardly become fainter laterally, but only 

 towards the apex. 



IV.B. — I have now described (all iu the E. M. M.) forty-nine 

 Hawaiian species of Geodephaga — a large proj)ortion I think for a 

 small isolated group of islands.

Choerocampa celerio at Banff. — I have liacl forwarded nie by Col. F. G-arden 

 Campbell, of Troup, Banff, N.B., a specimen of the rare Choerocampa celerio in fairly 

 good condition, caught by himself at Troup, on the 3rd inst. It was not quite dead 

 when I received it. — H. W. Wilson, Leigham Lodge, Leigham Court Ed., Streatham
