peculiarities relegate to Dyscohis rather than Anchomenus, if these two 

 genera are to stand. Without expressing any further opinion on that 

 point, I may say that the four Hawaiian species mentioned above seem 

 to me too closely allied inter se to be satisfactorily parted, and that as 

 members of either genus they must rank among the most extreme of its 

 aberrant forms). 



Blackburnia frigida, I have located with some hesitation. Its 

 eyes (though feebly developed in comparison of, say, a typical Ancho- 

 menus) are much more strongly developed than those of B. insignis, Sh., 

 and hlnptoides, mihi, and the defined suture between the 2nd and 3rd 

 ventral segments constitutes a further perplexity. Moreover, the 

 striation of elytra, and punctuation in general, are totally unlike those 

 of the other species of BlncMumia. The form of the head, however, 

 the very deep ventral sutures, the close adaptation of the elytra to the 

 hind body, and the general " distinctiveness " of facies, accompanied 

 by scarcely any tangible structural difference from AncJioviemis, all 

 point to this as its place.
