applies equally well. As in Cicindela, the species of this 

 genus seem, in their markings, to have a certain type from 

 which they do not often depart much. If you have not any 

 $ , will you ask Mr. Leonard to examine his insects for that 

 purpose ? 



Your 833 [= " Haltica tceniata Dejean, teste Leconte," 

 Harr. MSS. CataL] is not described, to my knowledge. I 

 brought it from the North, but it is not found here. Fabricius's 

 description of Gralleruca petaurista does not well apply to it. 

 The lines on the elytra are not ferruginous, but whitish, and 

 the epithet " crassissimus " does not at all apply to the thighs 

 of that insect. I am very sure I have that species in my col- 

 lection. It is a unique, gathered in North Carolina, which is 

 nearer its home, as Bosc brought his probably from South 

 Carolina. This insect is somewhat longer than your 333 (my 

 676), and nearly twice as broad ; the markings are ferruginous, 

 the elytra are punctured, so that the punctures are visible to 

 the naked eye ; the black spot on the thorax is large and 

 transverse ; and finally the thighs are crassissimi indeed ; they 

 are actually monstrous. 



Your 464 [= " Acupalpus conjunctus ? Say," Harr. MSS. 

 CataL], 74 [= " /Stenolophus cinctus Say," Harr. MSS. CataL], 

 and 763 [= " Feronia ( Omaseus) stygica Say," Harr. MSS. 

 CataL], you have marked Trechus. I have other species which 

 certainly belong to the same genus. But I am not sure about 

 its name. I know no more about Treclms than what is said 

 of it in the Edinburgh Encyclopedia. My difficulty is that 

 Latreille places it near ffarpalus, among those Thoracici which 

 have the "two anterior tarsi in the $ dilated," whereas I cannot 

 see any distinct enlargement in any of the specimens I have. 

 Is it so slight that it can only be regarded as a character 

 employed to suit a natural classification? I grant that the 

 greatest affinity of forms may be observed between them and 

 some of my specimens of Harpalus, but still I am uncertain on 

 that subject.
