220 THE ENTOMOLOGIST. 



similar cases of late emergence of this insect were recorded last 

 year (Entom., vol. xx., pp. 63, 106, and 135). 



The subject, considered more generally, is one well deserving 

 careful attention, and statistics of captures including numerous 

 species viewed in relation to date, if sufficiently extensive, would 

 lead to interesting results.

NOTE ON A SPECIES OF ACROPS FKOM JAPAN. 



By G. Lewis, F.L.S. 



In the ' Munich Catalogue ' there is only one species of this 

 genus (recorded from Sumatra), but in my collection I have three 

 species from Borneo, and, as I found it in S. Japan, I think the 

 genus may not only be represented by a fair number of species, 

 but that it may also be widely distributed in Eastern Asia. The 

 species are very difficult to differentiate, but the characters from 

 the four species before me seem to consist chiefly in the form of 

 the forehead, in the relative position of the eyes to each other, 

 and in the shape of the thorax. I have only seen eight Japanese 

 examples, but I infer there are no conspicuous sexual characters. 



AcROPS HIGONIA, n. Sp. 



Oblongo-ovalis obscure £enea, supra parum convexa ; fronte 

 lata, clypeo Iseviter emarginato ; fronte rugosa et ocellato-punctata, 

 oculos approximatis, pronoto angulos anticis modice productis, 

 posticis rotundatis; elytris reticulato-punctatis, obscure maculatis, 

 apicis obtusis ; antennis pedibusque concoloribus. Long. 4|- mill. 



The slight emargination in the anterior edge of the clypeus 

 has, under the microscope, an obscure projection in the middle; 

 the eyes are elliptical, and approach each other in the middle of 

 the neck, leaving only a narrow space between them. In one of 

 the Borneo species the eyes almost touch, in another the distance 

 is double that in higonia. The angles of the thorax anteriorly 

 are rather produced, but blunt ; and the hind angles are rounded 

 off, and not angulate or emarginate, as other species are. The 

 maculation of the elytra is diffused, and not ver}^ distinct ; in this 

 character it corresponds with one Borneo species, but in another
