only the stria are visible, the interstices sparsely clothed with stiff whitish hairs; legs entirely 
fulvous. . 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
A single specimen. 
9. Crepidodera (?) flaveola. 
Pale flavous (sometimes piceous below), the last joint of the antenne fuscous; thorax closely punctured and 
finely granulate, the transverse sulcus indistinct; elytra punctate-striate, the interstices minutely 
punctured. 
Length # line. 
Of somewhat ovate, medially widened shape; the head rather remotely but strongly punctured, the frontal 
tubercles obsolete ; antennae two-thirds the length of the body, flavous, the last joint fuscous or black, the 
second joint short and stout, the third thin, shorter than the fourth, the following joints rather robust; 
thorax transverse, the sides nearly straight, the angles obsolete, the surface minutely granulate and 
strongly punctured, the transverse sulcus, as well as the latera] longitudinal groove, nearly obsolete; elytra 
slightly depressed below the base, punctate-striate, the first two striz near the suture each formed by a 
double row of punctures, the others by a single row, the interstices very finely and sparingly punctured ; 
anterior coxal cavities closed. 
Hab. Panama, Volcan de Chiriqui, Taboga Island (Champion). 
This small species has all the structural characters of Crepidodera, but differs from it 
by the indistinct thoracic sulcus. It is not advisable to separate it from Crepidodera, 
which has been already divided into several sections (Ochrosis &c.). 
ORTHYGIA. (To follow the genus Crepidodera, p. 344.) 
Body ovate, convex; palpi slender; antenne filiform, long; thorax transverse, longitudinally grooved on either 
side at the base; elytra punctate-striate ; legs rather robust ; the tibie not channelled, each armed with 
a small spine ; the first joint of the posterior tarsi as long as the following two joints together; claws 
appendiculate ; prosternum narrow between the coxe, much widened towards the base; anterior coxal 
cavities closed. 
In having a longitudinal groove on either side of the base of the thorax this genus 
approaches Mantura, from which it differs in the broadly ovate, convex shape, and the © 
more transverse thorax. 
1. Orthygia nigritarsis. 
Fulvous or blood-red, the apical joints of the antenne, the apex of the tibiw, and the tarsi black ; thorax 
microscopically punctured; elytra finely and regularly punctate-striate. 
Length 14-2 lines. 
Head inserted as far as the eyes, the frontal elevations nearly obsolete, impunctate, the apex of the mandibles 
black; antenns extending to the middle of the elytra, the lower four joints fulvous, the rest black, the 
third and following joints nearly equal, slender; thorax much broader than long, the sides rather rounded, 
the anterior and posterior margins nearly straight, the anterior angles slightly produced the surface 
extremely minutely punctured, a short longitudinal groove (sometimes nearly obsolete) on either side at 
the base; scutellum triangular, smooth; elytra with ten regular rows of punctures, the interstices flat ; 
underside and legs fulvous, the posterior haif of the tibia and the tarsi black.
