he was employed with the Federal Horticultural Board on the 

 Pink Bollworm investigations in Texas. He had intended re- 

 turning to Cornell this fall to finish his education preparatory 

 to embarking on an active entomological career. 



A promising scientist, a keen student and a warm-hearted 

 lovable young man, who won all who met him, he leaves a sweet 

 memory behind him. To his mother and brother who survive 

 him our Society extends its profound sympathy. 



TWO NEW SPECIES OF ASAPHIDION FROM NORTH AMERICA 



(COLEOPTERA, CARABIDAE). 



BY H. F. WICKHAM. 



The genus Asaphidion is represented in Europe and Asia by 

 several species and is better known to Coleopterists under the 

 preoccupied name Tachypus. Belonging to the tribe Bembidiini, 

 it is easily distinguished at sight from Bembidion by the pubes- 

 cent surface and lack of elytral striae, while the large eyes and 

 greenish or olivaceous colors give it a facies recalling Elaphrus. 

 In fact the resemblance is so marked that several writers have 

 commented upon it. The only species credited to North America 

 is Tachypus elongatus Mots., described by that author as doubt- 

 fully from Sitka, Alaska, and accepted as native by Le Conte 

 and Henshaw. The type was loaned, for redescription, to Manner - 

 heim (Bull. Soc. Imp. des Nat. de Moscou, 1853, 146), who 

 emphasizes this doubt, while Mr. E. A. Schwarz, to whom I 

 am greatly indebted for assistance in tracing the references to 

 the European species, tells me that the vessel carrying the expe- 

 dition (Kotzebue's First Voyage), which collected the type, did 

 not touch at any Alaskan point, and that the specimen is prob- 

 ably from Kamchatka. In any event, the description given by 

 Mannerheim does not agree with either of the species in hand, 

 both of which inhabit the interior districts of the northwest. 



Asaphidion alaskanum, sp. nov. 



Form oblong, recalling a narrow Elaphrus. Piceous above, with metallic 

 green irrorations which become nearly solid on the sides of the pronotum 

 and of the elytra. Upper surface minutely alutaceous, finely and, in gen- 

 eral, sparsely punctured, the punctures tending to become somewhat muri- 

 cate, each having a short, subrecumbent seta, these setae silvery in most 

 places but more or less brownish or golden in restricted areas on the elytral 

 disk. Mandibles at apex and palpi (except the penultimate joint of the 

 maxillary, which is metallic) rufous. Antennae with the first four joints 

 more or less rufous basally, the remainder piceous. Legs rufous, the front
