The following very brief characters may enable you to distin- 

 guish the species which I have, if in your collection. No one 

 of them has the scales disposed in two oblique lines on the ely- 

 tra, as in your 133, which I have not seen ; nevertheless, in 

 the species here numbered 1, the lines may have existed, 

 though now obsolete. Will you inform me whether it agrees 

 in other respects with your 133. It will not be necessary for 

 me to publish your Nos. 133 ? and 163, and I only proposed it 

 on account of the paucity of species in the sub-genus which I 

 proposed to illustrate. 



1. Fuscous black, punctured; varied with ochreous and 

 black oval scales; thorax tri-foveolato-indented on the disk, pos- 

 terior angles robust, incurved at the points, mentum very much 

 produced and rounded in front beneath the mouth ; tarsal 

 grooves obsolete. Length |-J- inch. 



2. (your 133 ?) Brownish black, punctured, squamose ; tho- 

 rax canaliculate, posterior angles excurved ; elytra substriate. 

 N. Car. Length || inch. 



3. Black, punctured ; variegated with pale yellowish and 

 black cuneate scales above, and with silvery white, short, flat 

 bristles beneath ; thorax canaliculate, posterior angles nearly 

 rectangular. Length a little over -|- inch. Dublin, N. H. 



4. Dark chestnut, punctured; thorax covered with yellow 

 oblong-ovate scales ; elytra with paler cuneate ones ; body 

 beneath with short flat white bristles ; thorax canaliculate, pos- 

 terior angles excurved. Length ^ inch. Dublin, N. H. 



5. (your 163.) Castaneous, punctured, setose ; thorax elon- 

 gated, canaliculate, posterior angles excurved ; elytra striato- 

 punctate. Length nearly -|- inch. N. Car. 



6. Black, punctured ; head and sides of thorax with brilliant 

 reddish-tawny flattened bristles ; elytra with black, and body 

 beneath with white ones. Length nearly -^ inch. Can this 

 be the pennatus of Fabricius ? The thorax is not canaliculate, 

 nor the elytra striate. 



Your number 410 appears to be Necydalis thoracica Fabr.,
