to the truncate anterior angles; widest point just behind the middle; 

 carinae moderately prominent, distant, nearly parallel, terminating ante- 

 riorly in a pale tubercle ; callosities with a prominent tubercle ;- humeral 

 lobes subangulate, the posterior evenly rounded and smooth. Scutellum 

 one-third longer than broad, nearly flat, the sides gently arcuated to the 

 rounded apex, the basal field but slightly elevated, feebly tricarinate. 

 Elytra reaching on to the third tergal segment ; costa moderately expanded 

 at base ; femora with a few small white tubercles. Genital plates broad 

 and short, the basal about one-third the length of the sixth ventral seg- 

 ment, fully three times the length of the apical ; genital lobes short, trans- 

 verse, their greatest length hardly one third their width, their oblique 

 apex arcuated. 



Color testaceous varied with brown and tinged with rufous on the 

 abdomen, scutellum and disk of the pronotum; antennae becoming fuscous 

 toward the apex with the extreme tips of segments II and III pale; elytral 

 veins pale on a darker ground; tergum with a fuscous cloud on each 

 segment at the connexival suture, the disk of segment six and the genital 

 segment fuscous ; rostrum fuscous, paler at base. 



Described from one female taken on Vancouver Island, 

 September 6, 1899, by Rev. G. W. Taylor. This specimen is 

 paler than any allied form known to me.

5. Aradus taylori, new species 



Allied to aciitiis Say but with more slender antennas and 

 the body less maculated; blackish fuscous, narrow hind mar- 

 gin of humeri and some marks on the elytra pallid ; basal 

 lunule of the head and incisures of abdomen pink; sides of 

 pronotum strongly toothed. Length, male 7^ mm., female 

 9 mm. 



Male : Head a very little longer than broad across the eyes ; anten- 

 niferous spines long, acute, reaching nearly to the apex of first antennal 

 segment; preocular tubercle sm>all, the postocular large, obtuse; anterior 

 process as long as the width between the eyes ; the lateral impressed vittae 

 moderately deep, finely granulate like the rest of the surface. Antennae 

 as long as head and pronotum together, more slender than in acutus; 

 second segment one fifth longer than III and IV together, a little thick- 

 ened at apex; IV three fourths of III, its tip conical and clothed with 

 the usual grey pubescence. Rostrum pale, attaining hind margin of pro- 

 sternum. Pronotum more than twice wider than long, widest just behind 

 the middle ; humeral angles broadly rounded ; latero-anterior margin nearly 

 straight, finely crenulate as are the humeri, and in addition armed with 

 about four stout irregular teeth ; surface nearly flat, the longitudinal 

 carinae feeble, the median pair diverging a little posteriorly. Scutellum 

 flat, edges nearly rectilinear to the obtuse apex, but feebly elevated. 

 Elytra narrow, attaining the genital segment, the humeral expansion nar- 

 row. Genital lobes oblique at apex with their angles rounded. 



'Color blackish fuscous ; extreme base of vertex and incisures of con- 

 nexivum above and below pinkish ; venter dark castaneous ; narrow hind 

 edge of humeral lobes, a mark on the basal expansion of the corium and
