remainder of the underside of the body, piceous : side-covers bronzed 

 with a piceous tint. [Not G. analis Say. — Ent. Works ii. 520.] 



118. — Gyrinus MfNUTUS Fabr. — Length of body 2 lines. A single 

 specimen taken in Lat. 65^. 



Variety B. Body above blue black, with the sides, particularly of the 

 prothorax and elytra, bronzed; underneath piceous, with the lobes of the 

 metasternum, anus, and legs, rufous : epipleura rufo-piceous. In other 

 respects it precisely resembles the European specimens. \Vidc Le- 

 Conte, Pro. Acad. N. S., Phila., Dec. 1868, p.p. 370 and 372.]

[86.] 119. P.ederus riparius Fabr. — Length of body 3 lines. 

 Several taken in Lat. 54^. 



Head, breast, two last joints of abdomen, base of the tibiae and apex 

 of the thighs, black : prothorax, legs, and four first segments of the 

 abdomen testaceous : elytra dark blue ; antennae dusky. [Probably an 

 erroneous determination for P. littorarius, Grav.] 



120. Lathrobium puncticolle, Kirby. — Length of body 5 lines. 

 A single specimen taken in Lat. 54 . 



[87.] Body black, rather glossy, hairy except the prothorax. Head 

 obovate, minutely and thickly punctured ; mandibles, palpi, and what 

 remains of its mutilated antennae, dark chestnut : prothorax an oblong 

 square with all the angles rounded ; punctured, but not very thickly, with 

 scarcely any smooth longitudinal space : elytra longer than the prothorax, 

 thickly punctured, of a dark chestnut : legs maghogany, cubit armed with 

 a short wide tooth or prominence on the inner side at the base, the four 

 first joints of the hand are dilated, indicating probably that the specimen 

 is a male. This appears to be the representative of L. dcutatitm, E, 

 which it nearly resembles, but the elytra are considerably longer, the 

 colour of the legs is darker, and the humerus, or anterior thigh, is pro- 

 portionally smaller and has no tooth. [Taken in Canada.] 



. 121. Lathrobium gravexhorstii Kirby. — Plate ii. fig. 2. — Length 

 of body 4^2 lines. Two specimens taken in Lat. 54 . 



This species a good deal resembles the preceding, but the palpi, mouth, 

 scape of the antenna?, arid legs, are testaceous, the remainder of the 

 antennae is darker ; mandibles chestnut. Head oblong : anterior angles 

 of the prothorax scarcely rounded ; a distinct intermediate longitudinal 

 smooth space adjoining which is a series of punctures strikingly distin-
