1. Tomicus plastographus. (Tab. VII. fig. 6, apex of elytra.) 
Tomicus plastographus, Lec. Trans. Am. Ent. Soe. ii. p. 163 (Sept. 1868) '; Rhynch. N. Am. p. 364°. 
Tomicus integer, Bichh. Berl. ent. Zeitschr. 1868, p. 273 (March, 1869) °; Rat. Tom. p. 226%. 
Hab. Nortu America, New Mexico?, California ! 2 (Ricksecker).— Mexico? 4, Omilteme 
in Guerrero (H. H. Smith), Mexico city, Salazar, Toluca, Amecameca, Jalapa (Hége), 
Toxpam (Sal/é). 
Of the identity of 7. integer and 7. plastographus there cannot be any doubt. I 
have been able to compare a typical specimen of the former with examples sent me as 
T. plastographus from Monterey, in California, by Mr. Ricksecker, and answering fully to. 
Leconte’s description. It is the only known American Zomicus with four teeth on each 
elytron, and with the antennal sutures sharply angulate. Mr. Hoge has sent us long 
series, chiefly from Amecameca, the examples of which vary a good deal in size, colour, 
and development of the elytral teeth. 
It may be noted here, once for all, that whenever, as in this case, Leconte’s and. 
Eichhoff’s names published in 1868 are found to clash, the former have priority, 
contrary to what those writers themselves have supposed. For the date of publication 
of Eichhoff’s names, see Berl. ent. Zeitschr. 1868, p. xi, note. 
2. Tomicus interstitialis. (Tab. VII. fig. 7, apex of elytra.) 
Tomicus interstitialis, Eichh. Berl. ent. Zeitschr. 1868, p. 273*; Rat. Tom. p. 228%. 
Hab. Guaremata, Balheu, San Joaquin, and San Gerénimo in Vera Paz (Champion). 
—ANTILLES, Jamaica ! 2, 
A long series of this species was taken by Mr. Champion, the examples varying in 
colour from pale testaceous to ferruginous and piceous-black, and in size from 3°6 to 
54 millim. They agree completely with the type, now in the Chapuis collection, 
except that the interstitial punctures on the elytra are less close. 
8. Tomicus cribricollis. (Tab. VII. fig. 8, apex of elytra.) 
Tomicus cribricollis, Kichh. Ber]. ent. Zeitschr. 1868, p. 273°; Rat. Tom. p. 229°. 
Hab. Mexico! 2, Omilteme in Guerrero (H. H. Smith); Guatemaua, San Geronimo 
and San Joaquin in Vera Paz (Champion). 
Of the single Mexican example taken by Mr. Smith, and the eight specimens from 
‘Guatemala, not one corresponds rigidly with the type in the Chapuis collection. They 
are, as a rule, slightly smaller and less robust, the punctuation of the prothorax is 
variable in depth, but is weaker in all examples except that from Omilteme, and the 
interstices of the elytra, instead of being quite flat, show a very slight convexity. The 
size of the second and third elytral teeth and the extent of their coalescence is not 
constant and probably varies in the sexes. Though itis just possible that they are
