ments are also due to the authorities of the United States National 

 Museum, having in charge the collections of insects, for the loan of 

 all its material, to Mr. Charles Schaeffer, for the loan of specimens 

 collected by him in Texas, and to Messrs. Chas. W. Leng, John D. 

 Sherman, Jr., and J. B. Wallis, for the use of their specimens on the 

 broad principle of " help yourself to anything you want." The care- 

 ful collecting of Mr. J. B. Wallis, of Winnipeg, Manitoba, added two 

 new species to our known fauna, and his liberality large series of 

 specimens to my cabinet where, in several instances, my material 

 heretofore had been meager. 



BRYCHIUS Thomson. 



In describing this genus the use of the expression " thorax quad- 

 rate " seems to me inappropriate as far as our species are concerned 

 and also as to the elevatus Panz., the only European species I have. 



The thorax, while not obliquely narrowing from base, is decid- 

 edly transverse, being nearly, if not quite, one half wider than long. 



Brychius parvulus new species. 



Oval, strongly convex, laterally and longitudinally, pale olive green. 



Size: length 2]/^ mm,; width 1^4 mm. 



Head with the apical half pale yellow in color and faintly rugose and the 

 basal half infuscate and finely punctured ; broad between the eyes ; eyes round 

 and quite prominent ; antennas pale yellow. Pronotum transverse ; sides 

 slightly sinuate and finely margined ; not obliquely narrowed towards the 

 apex ; depressed at base between the depressions, or striolae ; striolse deep and 

 short, not extending over one third the length of pronotum ; finely, closely and 

 evenly punctured, except a narrow space each side where the punctures are 

 more scattered ; an infuscate area between the inipressions, darkest at base, 

 gradually fading to apex and leaving the sides pale yellow. 



The elytra, viewed from the side, are convex, decurved at about two thirds 

 from base, strongly convex laterally and immaculate ; punctures of the striae 

 fine, not deep and rather irregularly placed; some of the punctures darkened, 

 but not sufficiently so or regularly enough to produce stripes ; apices grad- 

 ually rounded and obtusely angulate at suture. 



The under surface of body and legs are uniformly pale yellow, except the 

 last abdominal segment. Prosternal process broadest at base, very gradually 

 narrowed to the front coxae, and beyond them suddenly and strongly con- 

 stricted ; fiat ; impunctate ; without margins. 



Hind coxae broadly rounded and without sign of exterior or sutural 

 angles ; punctures shallow and not closely placed. 



Owing to the manner in which the specimen is mounted it is impossible
