258 MEMOIRS ON THE COLEOPTERA 



quite as long as the remainder, the tibiae unmodified. Length (cf ) 10.0 

 mm.; width 2.8 mm. British Columbia (Inverness). 



Allied somewhat to rnbida Lee., but smaller and with deep black 

 and not fusco-ferruginous legs and much sparser elytral punctures. 

 The single example was one of the last captures of the Rev. J. H. 

 Keen before his final departure for England, and I take great 

 pleasure in naming it in honor of one to whom we owe so many 

 interesting discoveries among the Coleoptera of the Pacific coast. 



Strangalia Serv. 



There is a strong consistency of habitus pervading this genus, 

 which in our fauna consists of perductor Walker, obliterate,, abdomin- 

 alis, elegans and cruentata of Haldeman the last differing somewhat 

 in facies because of its shorter and less cuneiform elytra but con- 

 nected very well through plagifera, subhamata and plebeja Rand., 

 propinqua Bland, and vitiosa which is not by any means a variety 

 of obliterata,deleta, soror and plagifera of LeConte. Elegans is 

 not a variety of subhamata but quite distinct, as shown by the fe- 

 males in my collection, the prothorax being much broader in elegans, 

 as well as differently ornamented; the males of this species are 

 very much more slender than the females and very differently 

 colored, being largely black, the sutural black vitta being peculiarly 

 sagittiform in a way not suggested in the female. Abdominalis has 

 a marked peculiarity of thoracic sculpture and a different scheme 

 of elytral ornamentation; it might very rationally be separated as 

 a subgenus. The far western species allied to obliterata are numer- 

 ous, very uniform in ornamentation and facies and, so far as repre- 

 sented in my collection, may be defined as follows: 



Elytra each with a black discal spot near basal third; apical black area 



not extending to the tip but there becoming dusky rufous 2 



Elytra never with trace of the black discal area, the black apical area 



extending to the apices. . 4 



Elytra similarly devoid of the black discal area but rather brightly pale 



at apex 7 



2 External apical angles of the elytra very acute and slightly everted; 



submedian black band of the elytra broadly interrupted at the suture. 



Length (9 as usual, only to the elytral tips) 15.8 mm.; width 5.5 



mm. Vancouver Island perductor Walk. 



External apical angles acute but not in the least everted, the external 



outline of the elytra continuing the feeble arcuation to their tips. .3
