OF WASHINGTON. 75 
Tomicus mexicanus n. sp. Female type, length 4.8 mm.; elongate, 
cylindrical, ferruginous, clothed with long fine hairs; declivity of elytra 
excavated and armed each side with three teeth, the first very small, 
acute the second triangular, acute the third widely separated, long, 
cylindrical and thickened toward tip. Head, front flat, subopaque, 
densely granulated with shining median impression and a small shining 
tubercle on the anterior margin; antennal club with two obscure, broadly 
curved sutures on the anterior face; the posterior face pubescent and 
with one indistinct broadly curved suture. Prothorax as broad as long; 
anterior two-thirds roughened with small asperities, becoming finer to- 
wards the sides; posterior third smooth, punctured, with narrow dorsal 
longitudinal space. Elytral punctures coarse, those of the striae coarser 
and denser than those of the interspaces, first to fourth in distinct row, 
but the punctures on the sides are densely confused. 
Male type, length 5 mm., same form and general characters as the 
female, except that the pubescence is less dense; the frontal impression 
deeper and opaque, the marginal tubercle more prominent, and the 
margin more distinctly granulated; the teeth of the declivity distinctly 
coarser, especially the first and second. 
$ and c? Types. No. 7513 U. S- Nat. Mus., Mexico City, 
Mexico, 1903, in firewood, Prof. A. L Herrera, collector, and 
bearing his number 865. 
Two additional males from the same lot are of the same 
size and color of the female type, and agree exactly with the 
secondary sexual characters in the male. 
This is evidently the species mentioned by Blandford 
(Biol. Centr. Amer., Vol. IV, Part 6, page 188), on the authority 
of Eichhoff, under T. concinnus Mann. It is, however, easily 
distinguished from specimens I have identified as concinnus by 
its reddish color and very much coarser puncture of the 
elytra and pro thorax. Blandford compared his specimens 
with one from California, which, although closely allied to 
concinnus, evidently represents an undescribed species. T. 
concinnus is a boreal form extending down the coast into the 
United States with the Sitka spruce, in which* it lives, while 
the California species is common in Pinus radiata in middle 
California and Pinus murrayana of the higher Sierras and 
extending, with this tree, as far north as Priest Lake, Idaho. 
Tomicus integer Eichh. The specimens in our collection 
from Mexico received from Mr. Blandford under T. plasto- 
graphus belong, without doubt, to T. integer Eichh., which is 
a good species, distinct from T. plastographus Lee., with which 
it has been confused. The type specimen of the latter which 
I have examined agrees with specimens from Monterey pine 
in California, but LeConte made the mistake in this, as he
