NORTH AMERICAN BOSTRICHIDAE 91 



Female. — Differs from the male in having the sutural margins on the 

 apical declivity of the elytra moderately gibbose, rugose but not den- 

 tate on the dorsal surface, the gibbosity gradually, broadly rounded 

 when viewed in profile, and the surface of the apical declivity scarcely 

 depressed along the sides of the margins. 



Length 3.5-5.5 mm., width 1.2-1.7 mm. 



Type locality. — Of scabratus, Peru ; type was in the Berlin Museum. 

 Of vitis, Illapel, Coquimbo, and Concepcion, Chile; type in the Paris 

 Museum. 



Distribution. — This species is recorded from Peru, western Bolivia, 

 and northern Chile. Specimens of this species have been intercepted 

 at New York in packing cases containing grapes from Chile and with 

 corn on the cobs from Peru. 



Hosts. — In Chile this species lives in the stems of grapes. 



Blanchard (1851) described Bostrichus vitis from Illapel, Coquim- 

 bo, and Concepcion, Chile, without designating any place as the type 

 locality. Lesne (1899) placed Bostrichus vitis Blanchard (1851) as 

 a synonym of Bostrychulus scabratus Erichson (1847). 



Micrapate mexicana, new species 



Male. — Brownish black, elytra usually more reddish, and antennal 

 club, palpi, and tarsi brownish yellow. 



Head very densely, finely punctate or granulose, sparsely clothed 

 with long, semierect, whitish hairs on clypeus and front of head, 

 with long, fine, longitudinal, parallel costae on occiput; clypeus 

 broadly, shallowly emarginate in front; clypeal suture not distinct; 

 labrum finely, sparsely punctate. 



Pronotum quadrate, widest at middle, shallowly emarginate in 

 front; sides broadly rounded, with a small, broad tooth at apical 

 angles; posterior angles broadly rounded; surface sparsely clothed 

 with short, recumbent, whitish hairs, densely, finely punctate on basal 

 half, densely, irregularly dentate on apical half, the teeth broad, 

 semierect, variable in size, acute at apices, and rasplike. 



Elytra at base slightly narrower than pronotum at middle; sides 

 nearly parallel, broadly, conjointly rounded at apices; apical con- 

 tour (when viewed from above) broadly rounded; surface sparsely 

 clothed with moderately long, recumbent, yellowish hairs, densely, 

 coarsely, confluently punctate over entire surface; apical declivity 

 arcuately deflexed and not depressed along sutural margins; sutural 

 margins on apical declivity not gibbose or expanded laterally at 

 middle, but narrowly, uniformly elevated along entire length, the 

 sides not abruptly deflexed. 



Abdomen beneath finely, densely punctate, smooth between punc- 

 tures, rather densely clothed with long, recumbent, whitish hairs, 

 with a few long, erect hairs intermixed; last visible sternite broadly 

 rounded at apex. Posterior tibiae and tarsi with long, fine hairs. 



Female. — Differs from male in having a small vague depression 

 at apex of last visible abdominal sternite. 



Length 4-6 mm., width 1.5-2 mm. 



Type locality. — Mexico. 



Type, allotype, and paratypes. — In the United States National 

 Museum, No. 58315.
