338 NITIDULID. 
C. externus, has the disc of the thorax much more coarsely punctured. I have seen 
only one male that I can refer to C: externus, and it has the sculpture slightly coarser 
than it is in the female.

Camptodes molestus, Kirsch, Berl. ent. Zeitschr. 1873, p. 147*; Reitter, Verh. Ver. Briinn, xii. 1, 
pp. 125, 189°. 
Hab. Mexico 2,—Soutn America, Peru !2. 
On comparing Reitter’s description and remarks with that of Kirsch it seems probable 
that Reitter may have had more than one species before him when treating of C. mo- 
lestus, and that his identification of the Mexican and Peruvian examples may prove to 
be incorrect, in which case this name should be removed from our list of species. 
27. Camptodes adustulus.

Heb. Mexico}. 
This name probably refers to C. communis, about which, as is not to be wondered at, 
Reitter appears to have been rather confused ; he distinguishes it (in addition to certain 
characters of punctuation which are unimportant) by the fine punctuation of the pygi- 
dium and by the elytra being dark behind; these characters are both given by Erichson 
as applying to C. communis. The statement as to the absence of a sutural stria is no 
doubt due to an error of observation. I have not seen any Camptodes without a sutural 
stria, and Reitter’s remark (Verh. Ver. Briinn, xii. 1, p. 102) shows that he believed 
the stria to be absent, when it is, in fact, deep but placed very near the suture. 
28. Camptodes discoideus. 
Camptodes discoideus, Reitter, Verh. Ver. Briinn, xii. 1, p. 1251. 
Hab. Mexico}. 
This is perhaps an insect allied to C. cognatus, and with blackish vitte on the elytra, 
as I have recorded in a variety of C. cognatus ; but it is impossible to come to a certain 
conclusion as to it from Reitter’s tables. 
29. Camptodes cognatus, sp. n. (Tab. X. figg. 25,3; 25a, labrum and man- 
dibles.)
