KEVISION OF GENUS TACHYPORUS — BLACKWELDER 51 



Type locality. — Indiana. 



Localities represented. — The present collection contains specimens 

 from the following localities: New Hampshire, Massachusetts, New 

 York, New Jersey, Pennsylvania, District of Columbia, Virginia, 

 North Carolina, Florida, Alabama, Mississippi, Ohio, Michigan, Il- 

 linois, Wisconsin, Lake Superior, Iowa, Missouri, Kansas, Texas, 

 North Dakota, Colorado, Wyoming, New Mexico, Montana, Utah, 

 Nevada, Idaho, California, Oregon, Washington, Saskatchewan, On- 

 tario, British Columbia, Yukon Territory. 



Remarks. — In Horn's system this species was not separable from 

 his chrysomelinus. His series contains at least two species, besides 

 a specimen of elegant. This is the most uniformly pale species and 

 can generally be told by this character. It has a wider range than 

 any other American member of the genus. 



TACHYPORUS PULCHRUS Blatchley 



1910. Tachyporus pulohrus Blatchley, Coleoptera or beetles of Indiana, p. 447. 



Original description. — "Reddish-yellow, strongly shining. Head, 

 basal fourth of thorax, basal half or two-thirds of elytra and last 

 two segments of abdomen, black; under surface piceous. Elytra 

 without visible punctures, very sparsely and finely pubescent. 

 Length 3 mm." 



Type locality. — Indiana, 



Remarks. — This species has only been recorded once. If the de- 

 scription of the color of the thorax and elytra is correct, it is quite 

 distinct from any other species. No specimens are available to me, 

 and I have assumed the absence of the sutural series of punctures. 

 I believe it is the only species of Tachypoi^s described as having 

 the base of the pronotum black and the apex pale. This is certainly 

 not the same as ohtusvs Linnaeus of Europe, which has the pronotum 

 entirely pale. 



TACHYPORUS OREGONUS, new species 



Form robust and convex. Piceous-black; antennae, trophi, pro- 

 thorax, and elytra testaceous, legs somewhat darker; pronotum with 

 indefinite darker spot at middle, and elytra with large scutellar 

 spot extending to apical three-fourths and a narrow humeral stripe 

 nearly black. Antennae with segments all longer than wide, ter- 

 minal not quite twice as long as tenth. Third segment of maxillary 

 palpi scarcely dilated, fourth acicular. Pronotum with sides nearly 

 straight in apical half; not distinctly wider than elytra. Elytra 

 finely submuricately punctured, the punctures frequently grouped 

 into transverse rows of two or three; without sutural series; mar- 

 ginal series of four punctures, and with an additional discal punc-
