ANTHICUS. 235 
laterally, the disc appears to be very little depressed between the anterior and posterior portions), the 
excavation in the flanks not so deep; the rest, including the male characters, as in A. bactrianus. 
Length 23 millim. (¢.) : . 
Hab. Panama, Pefia Blanca 2000 feet (Champion). 
Two male examples. In the form of the thorax this insect is somewhat intermediate 
between A. bactrianus and A, obscurus and its allies. The posterior portion of the 
thorax is raised above the level of the anterior portion, but is more rounded and less 
conically elevated than in A. bactrianus.

Hab. Nortu America, Delaware 3, New Jersey °, Texas, California 1, San Diego ?.—

(Hoge, H. H. Smith). 
We have received four examples of this species from within the limits of our fauna, 
two of the typical form and two of the var. 8; others from Mexico are also contained 
in the collection of M. Réné Oberthiir. These agree well with La Ferté’s types. The 
insect appears to be widely distributed in the United States. A. californicus is an 
ally of the European A. humilis, Germ., and equally variable in colour ; the head is 
about as long as broad ; the thorax is strongly constricted behind, obsoletely bituber- 
culate in the middle at the base, and very distinctly punctured, the punctuation 
_ becoming denser towards the base; the elytra are long, without post-basal depression, 
and closely and rather coarsely punctured ; the upper surface is shining and sparsely 
pubescent. The locality “California” requires confirmation. 
21. Anthicus invalidus. (Tab. X. fig. 14.) 
Anthicus invalidus, La Ferté, Monogr. Anthic. p. 136°. 
Two specimens of this species are contained in the La Ferté collection: one, the 
type, from Colombia, is in a very mutilated condition and without antenne ; the other, 
from Panama, labelled .A. aldicornis, Motsch., is not mentioned by the author in his 
monograph. We give a fresh description from the additional examples captured by 
myself in Guatemala; these differ from La Ferté’s definition of the species in having a 
distinct post-basal depression to the elytra. 
Elongate, reddish-testaceous or ferruginous, very shining; the elytra with the base rather broadly and a 
common transverse fascia just beyond the middle piceous or brownish, sometimes with only a large spot 
at the shoulders and another at the sides at the middle brownish; the upper surface clothed with long 
erect, scattered hairs, those on the elytra serially arranged. Head nearly as long as broad, rounded at 
the sides behind, foveate on each side in front and with a few widely scattered fine, deep punctures ; the 
eyes black, coarsely granulated, large and prominent ; antenns long and slender, the apical three or four 
and the two basal joints testaceous or flavo-testaceous, the others black or piceous, the apical joint acumi-
