CARTODERE. 
Cartodere, Thomson, Skand. Col. v. p. 219 (1859) ; Belon, Rev. Ent. Fr. 1897, p. 183; Fall, 
Trans. Am. Ent. Soc. 1899, p. 135. 
There are about thirty described species of this genus. They are very minute 
elegant insects, and some of them appear to be nearly cosmopolitan. 
1. Cartodere filum. 
Lathridius filum, Aubé, Ann. Soc. Ent. Fr. 1850, p. 3341; Fall, Trans. Am. Ent. Soc. 1899, 
p. 189°; Belon, Rev. Ent. Fr. 1897, p. 187°. 
Hab. Norte America, United States 2.—Mexico 3?.—Europe 1. 
Said by Belon* to be very common in Mexico, and reported by Fall to have 
occurred two or three times in the United States. We have received no species that 
resembles C. filum from any part of our region. Belon does not mention the insect in 
his recapitulation of the Lathridiide of South America, and we may be pardoned for 
supposing that his subsequent citation ? of it as Mexican is an error. 
2. Cartodere falliana, sp.n. (Tab. XIX. fig. 4.) 
Convexa, minus elongata, ferruginea; prothorace transverso, inequali, ante medium et ante basin profunde 
transversim depresso; elytris dense profundeque punctatis, singulo longitudinaliter bicarinato. 
Long. 13 millim. 
Hab. Mexico, Cordova (Sallé). 
Antenne 10-jointed, the club 2-jointed; basal joint very large, subglobose ; second 
joint large, globose, only about one-fourth the size of the basal one; third joint sub- 
globose, not half the size of the second ; fourth joint very long and slender ; fifth to eighth 
each slightly shorter and broader than the preceding, each longer than broad; ninth 
large, triangular, quite as long as broad. Head largely explanate on each side; eyes 
small, convex, each consisting of seven or eight coarse facets; postocular interval as 
long as the diameter of the eye. Thorax with the posterior angles free, projecting 
backwards, bearing two transverse depressions. Elytra densely covered with large 
deep depressions, the suture slightly carinate, the second and fifth interstices strongly 
carinate. One specimen. 
I have named this charming little insect after Mr. H. C. Fall, who has made 
the best study of these forms. C. falliana is very distinct from C. filum, but it 
is not necessary to separate it as a genus at present. The under surface is impunctate, 
but very deeply grooved ; the peculiar circular elevation of the metasternum of C. filum 
is not present, neither are the peculiar plice of the first ventral plate.
