Notes on the Genus Hetaerius and Descriptions 

 of three New Species (Coleop,) 



By J. O. Martin, Berkeley, California 



(Continued from page 225.) 



Hetaerius nitidus very closely resembles brunnipennis Rand ; 

 but in that species the lateral thoracic area is crossed at 

 basal third by a distinct sulcus, represented in nitidus by a 

 foveate depression. In brunnipennis the lateral thoracic 

 area is coarsely punctate, in nitidus it is very finely so and 

 the punctures are fewer in number. The interstrial spaces 

 of the elytra in brunnipennis have coarse scattered punctures 

 which are lacking in nitidus. The pygidium in brunnipennis 

 is smooth, in nitidus punctate and hairy. They agree in 

 having the margined area of the prosternum closed by the 

 meeting of the marginal striae. 



Hetaerius hirsutus sp. nov. 



Body oblong, shining, castaneous, upper surface feebly convex. 



Head piceous, vertex concave, punctate, portion next to thorax moder- 

 ately, coarsely punctured, each puncture with a coarse branched hair, 

 cephalic portion more finely punctured without hair; front smooth, shin- 

 ing, impunctate. 



Thorax two-fifths wider than long, slightly narrowed in front, divided 

 longitudinally by two suture-like diagonal grooves into a discal and two 

 lateral areas; lateral areas again divided by a deep transverse sulcus at 

 basal third; discal area slightly longer than wide, a little less than one-half 

 as wide in front as at base, bordered laterally by a shallow sulcus which 

 is smooth, shining and impunctate; central portion of discal area smooth, 

 shining, impunctate, between this rounded impunctate portion and the 

 impunctate bordering sulcus is a roughly triangular area with base at 

 upper edge of elytra and extending slightly less than two-thirds the length 

 of disc which is coarsely and thickly punctured, each puncture bearing a 

 long branched hair, depressed and directed caudad, forming a brush-like 

 bunch at its outer basal portion ; along the apical border of discal area are 

 ten to twelve punctures, each with a depressed, squamose, fringed hair; 

 lateral area of prothorax widest at its cephalic end, thickly, coarsely 

 punctured, apical punctures bearing depressed, squamose, fringed hairs; 

 in the lateral and basal punctures the hairs are not squamose but are 

 long, pointed and branched, forming at the edge of the transverse sulcus 

 a brush-like tuft which nearly conceals the sulcus; posterior part of lateral 

 area piceous, shining, tuberculate, lateral edge with numerous long,
