638 Guleopterological Notices, VI. 



Head less minutely and very closely punctate; legs pale. 



Elytra finely, densely sculptured and pubescent; prothorax more rapidly 



narrowed anteriorly than posteriorly inuriiia Fab. 



Elytra coarsely and much more rugosely sculptured, more coarsely and 

 sparsely piibescent; prothorax equally oblique anteriorly and poste- 

 riorly, widest at the middle OTicollis n. sp. 



Last joint of the antennae but slightly longer than the penultimate; body red- 

 brown throughout, the head more oblong briiiiuea n. sp. 



Judging by the tigure of 31. linearis Newm., reproduced by La- 

 Ferte, it seems impossible to associate it with any species of Ma- 

 cratria now known. If rediscovered it will probably prove to be 

 the type of a distinct genus, which must be called Maci'atria, the 

 species here tabulated to be then known as Macrarthria Er. 



m, OTicollis. — Moderately slender, black, the legs, antennse and palpi 

 ochreo-testacous, the femora feebly nubilate with brown near the apex and the 

 ninth and tenth an tennal joints darker toward base; pubescence moderately 

 dense, yellowish, readily removable. Head as long as wide, broadly subtrun- 

 cate at base, paler toward apex, the eyes separated on the front by rather less than 

 twice their own width; antennse about as long as the head and prothorax, fili- 

 form, the ninth and tenth joints subequal and each one-half longer than the 

 eighth, second very nearly as long as the third. Prothorax two-fifths longer than 

 wide, one-half longer and jiist visibly wider than the head, the sides evenly 

 and strongly arcuate from apex to base, the base, immediately in advance of 

 the basal depression, strongl}- rounded, rather more prominent than the basal 

 bead and more feebly sculptured; disk feebly, evenly convex, very densely 

 punctato-rugose. Elytra at base one-third wider than the prothorax, a little 

 more than twice as long as wide, the sides straight and very feelily convergent 

 from base to apex ; disk rather shining when denuded, roughly and seriately 

 asperato-rugose, the intervals finely, densely punctato-rugose. Under surface 

 minutely, densely punctate, the legs stout. Length 4.5 mm. ; width 1.0 mm. 



New York. 



The male type has the fifth ventral not longer than the fourth, 

 broadly, transversely truncate at apex and very broadl}^, feebly 

 impressed on the disk almost throughout the width. I have for 

 the present associated with the type two females which, however, 

 have the prothorax widest at apical third. 



M. liriinnea. — Moderately stout, the male more slender, dark red- 

 brown, the head paler, rufous, the antennse, palpi, anterior and intermediate 

 legs paler, ochraceous; hind legs piceous; sculpture throughout fine, very 

 dense, the surface not shining; pubescence short, very dense, yello^\ish-cine- 

 reous in color. Head oblong-oval, as long as wide, finely, densely punctate, 

 truncate at base; eyes separated by twice their own width; tempora strongly
