240 HETEROMERA. 
29. Anthicus quadriplagiatus. (Tab. X. fig. 19.) 
Anthicus (Ischyropalpus) quadriplagiatus, La Ferté, Monogr. Authic. p. 148°. 
Hab. Panama, San Lorenzo in Chiriqui (Champion).—CoLomBIA 1. 
Three female specimens of this species were captured by myself in the “ tierra 
caliente” of Chiriqui; they agree perfectly with the type contained in the La Ferté 
collection. A. sericans (Er.), La Ferté, from Peru and Brazil, is a closely allied form. 
The subgenus Jschyropalpus was proposed by La Ferté to include these and some other 
species from Tropical South America, all of comparatively large size ; they have the 
thorax greatly rounded and dilated at the sides anteriorly, abruptly and obliquely 
narrowed from about the middle, slightly dilated at the base, the flanks concave, and 
the lateral margins rather prominent. In A. guadriplagiatus the entire upper surface 
is very densely and finely punctured and almost opaque; the head and thorax are 
ferruginous ; the elytra reddish- or flavo-testaceous, with an ill-defined triangular scutellar’ 
patch, a common transverse fascia a little beyond the middle, and the suture narrowly, 
piceous or brownish. The elytra are long, parallel, and rather depressed. The form 
of the head is well shown by La Ferté (op. cit. t. 27. fig. 23). The thorax is as wide 
as, or even wider than, the head. 
30. Anthicus exiguus. (Tab. X. fig. 20.) 
Short, of a uniform testaceous colour, slightly shining, thickly clothed with fine, silky, appressed, yellowish 
pubescence. Head large and broad, somewhat angularly extended on either side behind, coarsely and 
closely punctured, with a smooth central line, the occiput distinctly impressed, the eyes black and mode- 
rately prominent ; antenne short, about reaching the base of the prothorax, entirely testaceous ; prothorax 
broader than long, as wide as or wider than the head (in some examples more strongly transverse than in 
others), moderately convex, broadest in front and obliquely narrowing thence to the base, the surface 
finely and densely punctured, the base very obsoletely margined ; elytra short, moderately convex, rounded 
at the sides, the humeri obtuse, the base slightly emarginate, the surface densely but less finely punctured 
than that of the prothorax; legs entirely testaceous; fifth ventral segment truncate and unimpressed in 
the male. , 
Length 13-13 millim. (¢ 2.) 
Hab. GUATEMALA, Champerico (Champion). 
Found in plenty by myself on the Pacific coast. This minute species is allied to the 
European A. bimaculatus, Illig., and to the North-American A. maritimus, Lec., and 
A. ictericus, La Ferté ; it differs from A. ictericus, which it resembles in its small size, 
in having the head very much more coarsely and less closely punctured and also more 
rounded at the sides behind (the head in A. ictericus being broadly truncate at the base). 
The type of A. ictericus is not contained in the La Ferté collection, but Dr. Horn has 
kindly forwarded an example of the species for examination. This insect, as noted by 
Leconte (Proc. Acad. Phil. vi. p. 102), is from the Atlantic coast.
