216 MEMOIRS ON THE COLEOPTERA 



conical rather than cylindrical, but Say's species has probably been 

 correctly identified. 



Evodinus Lee. 



Besides the type of this genus, named Leptura monticola by 

 Randall, there is another rather closely allied species in my cabinet 

 as named below. The genus Evodinus, of recent years suppressed 

 and united with Pachyta, is valid, the prothorax being wholly as in 

 Stenocorus and not at all like Pachyta, and the elytral ornamentation 

 as in many true Lepturids; it is abundant in the European fauna, 

 numerous species being listed under the name Evodinus in the recent 

 European catalogue. 



Evodinus vancouveri n. sp. Male very slender, deep black, dull and 

 finely, very densely punctate, the elytra slightly shining though minutely, 

 deeply and very closely punctured, black, the humeri and a broad and 

 very irregular common sutural vitta, from behind the scutellum to 

 apical sixth or seventh, pale luteo-albid, the vitta contracted near basal 

 fourth, linearly expanded behind the middle and bifurcating slightly 

 at its posterior limit; head nearly as in monticola, the antennae very 

 slender, black throughout and as long as the body; prothorax as in that 

 species but narrower, more elongate and very much less densely pu- 

 bescent; elytra similar but narrower and with the small decumbent hairs 

 sparser. Female throughout in form, sculpture and ornamentation nearly 

 as in the female of monticola, except that it is less stout and that the pro- 

 thorax is much narrower, more elongate and less pubescent, the antennae 

 deep black, and that there is a bilaterally abbreviated black basal fascia 

 involving the scutellum; the antennae are much shorter than in the female 

 of monticola and especially with shorter outer joints, the hind tarsi 

 notably shorter. Length (cf 1 ) 9.8, (9) 9-5 mm.; width (o 71 ) 2.8, (9) 

 3.2 mm. Vancouver Island. 



The difference between the almost wholly black elytra of the 

 male and the pallid, laterally distantly trimaculate elytra of the 

 female, is remarkable and never occurs, so far as noted, in monticola; 

 the apex also is black, and the discal spot near basal fourth in the 

 female is very small. 



Parapachyta n. gen. 



The genus for which this name is proposed is also allied to 

 Pachyta, but is very different in general habitus and in many 

 important structural features, the body being much more elongate 

 and the elytra more nearly parallel, never so peculiarly cuneiform 

 as in Pachyta. It differs radically from Pachyta in the more de-
