Barin/E 345 



notum squamose throughout, though unevenly, and the propleura 

 are not denuded; the scales of the elytra are more uniformly oval 

 and dense, though similarly aggregated in white spots among the 

 pale brown scales of the general surface. I formerly held amer- 

 icana to be the same as scolopacea, but more careful observation 

 with ampler material, shows that they are different. 



Of those species now in my collection, it is evident that the 

 European 5eZ/a/a and spoliata Boh., alhosignata Jek., of Senegal, and 

 the Japanese orientalis, also belong to this genus.* 



Pycnobaris Csy. 

 The Colorado specimen formerly placed with typical Texan 

 examples of pruinosa Lee, proves to represent a rather closely 

 allied but apparently distinct species, which may be described as 

 follows : 



Pycnobaris canonica n. sp.- — Stout, oblong-oval, convex, not shining, 

 evenly clothed throughout above and beneath with slender and not very 

 dense white scales; beak three-fourths as long as the prothorax, thick, 

 arcuate, its dense scales conspicuous basally, abruptly ending at the 

 smooth and glabrous head; prothorax large, nearly as in pruinosa, but 

 with the sides more strongly constricted apically, the apex more definitely 

 tubulate; punctures less coarse, dense throughout and without smooth 

 median line; basal lobe small, with more conspicuous and dense white 

 vestiture, the scutellum transverse, also with coarser and more distinct 

 scales; elytra throughout nearly as in pruinosa but broader, scarcely a 

 fourth longer than wide, two-thirds longer than the prothorax, the 

 lineiform scales in the punctures at the bottom of the moderate grooves 



* The European species of Boris, as represented by timida, carbonaria, laticollis, 

 arlemisicB, quadralicolUs, and many more, resemble the American species assigned to 

 the genus in general features — in their nude surface, antennal club and mandibles — 

 but they are in general very much more feebly sculptured. Some of those regarded 

 as 5an5 cannot remain there, and two have recently been separated by Reitter to 

 form the genera Ulobaris and Neobaris; the following in addition should be proposed: 



Orthobaris n. gen. — The type of this genus is Boris cuprirostris Fabr. The body 

 is very slender, nude above and feebly sculptured, apparently always brightly me- 

 tallic green, cupreous or bluish in color, with the beak differing considerably in the 

 sexes and the prosternum obtusely canaliculate along the middle. Thepygidiumisas 

 in Boris and the other genera here mentioned. 



Some other species entering Orthoboris are angusla Brull., prosina Boh., and nili- 

 dula Bris. 



Such species as cxrulescens Scop., picicornis Marsh., chlorizons Germ., and corin- 

 thia Fairm., which are placed in the same group as cuprirostris in the European cata- 

 logue, belong to the genus Boris and not to Orthobaris, although the last named 

 species is very isolated even there.
