DICLIDIA.—PENTARIA. 251 
middle of the disc also, and usually with an oblique branch extending downwards), and the suture. at the 
base narrowly, piceous. Eyes coarsely granulated, black ; antenne testaceous, the intermediate joints a 
little darker in one example, very long and slender, thickening a little outwardly, distinctly shorter in the 
female than in the male, joints 3 and 4 equal in length, each about as long as 1 and 2 together, 5 much 
shorter than 4, 5-7 decreasing in length, 8-10 wider than 7, subtriangular, equal, 11 ovate, much longer 
than 10; prothorax about one half broader than long, the sides rounded and rapidly converging from a 
little before the base, the hind angles subrectangular ; beneath in great part infuscate ; legs testaceous or 
fusco-testaceous, very long and slender, the penultimate joint of the front and middle tarsi as long as the 
preceding joint, and strongly bilobed. 
¢. Abdomen with two long flattened appendages proceeding from the tip (between which the central sheath 
of the cedeagus is extruded), the appendages concave and clothed with long fine hairs within, widened out- 
wardly, and very obliquely truncate at the apex; the sixth ventral segment exposed, fully half the length 
of the fifth, and finely carinate down the middle behind ; the fifth ventral segment unemarginate. 
Length 34-4 millim. (¢ 2.) 
Hab. Gexremata, Cerro Zunil 4000 feet, Panajachel 5000 feet (Champion). 
One male and four female examples. This insect has much the facies of an Hallo- 
menus. It differs from the Texan D. letula, Lec., a specimen of which has been kindly 
communicated by Dr. Horn, in the strongly angulated and more numerous dark markings 
of the elytra (these being equally variable in extent) and in the infuscate thorax; and 
also in the unemarginate fifth ventral segment in the male. The abdominal appendages 
of the male are only visible when the genital organs are extruded.

Of the six described species of Pentaria four are from the United States. The genus 
proves to be well represented in Central America, whence ten species are now recorded ; 
it evidently replaces Anaspis in the warmer regions of the New World. The species 
here referred to it agree in having the fourth joint of the four anterior tarsi bilobed 
and nearly equal to the third in length and breadth, the posterior tibie long and 
slender, and the prothorax and elytra transversely strigose. Most authors state that the 
sixth ventral segment is visible in this genus: in some of our species it is just visible 
beyond the fifth, in others (in the males especially) it is well exposed, but in several 
cases (in both sexes) it is completely covered by the fifth. The ventral segments are 
apparently similar in form in the two sexes of Pentaria, except in P. trisiqnata, in 
which the fifth is triangularly emarginate and does not cover the sixth. In P. canescens 
the tibies show distinct traces of oblique grooves on their outer face. ‘The apical joint 
of the labial palpi appears to be more slender in this genus than in Anaspis, and less 
abruptly truncate at the apex.
