242 CLASS INSECTA. 



XX. 2, very similar to the Elaphrus riparkcs ; two lines 

 in length ; the corslet a little more narrow than the head, 

 in the form of a truncated heart, as long as broad. The 

 eyes large ; under part of the body of a blackish green, 

 upper part bronzed, and marbled Avith coppery red ; two 

 large points sunk near the suture, on each case ; base of the 

 antennae, palpi and feet, yellowish. Very common in the 

 environs of Paris.* 



Trechus. Clairv. 



Which have the last articulation of their external palpi as 

 long or longer than the preceding, of the same thickness at 

 its origin, so that these two articulations form, when united, 

 a fusi-form body.-f-

■f- Trechus rubcns, Clairv. Entom. Helv. II. ii. B. b. The carabus meru- 

 Uanus, which he represents in the same plate, A. a. is a stenolophus, Cara- 

 bus micros, Panz. Faun. Insect. Germ. XI. 4. The G. Masoreus of MM. 

 Ziegler and Dejean appears to me to border on that of Trechus. The 

 species on which it is founded is very near the harpalus collaris of M. Gyl- 

 lenhall. The maxillary palpi terminate, as well as those of Trechus, in 

 the manner of a spindle, only the last articulation but one is much shorter 

 than the following. The anterior tarsi are slightly dilated in the males. 

 This insect appears to connect the trechus with various smaller species of 

 Stenplophi of M. Dejean.

 more narrow and more elongated, with subisometric corslet, in the form
