PRIONODERA.—PROMECOSOMA. 219 
4, Prionodera limbata. (Tab. XL. fig. 24.) 
Fulvous; the sixth and seventh and the terminal two joints of the antenne black; thorax bidentate at the . 
sides ; elytra metallic green, deeply punctured and transversely rugose, the lateral and apical margins 
_ fulvous. 
Length 3 lines. 
Head rather closely impressed with large and small punctures; antenne fulvous, the sixth and seventh and the 
apical two joints black; thorax about one half broader than long, the sides with two more or less distinct 
teeth, the anterior angles produced, the surface irregularly and rather closely punctured, the punctures 
unequal in size; scutellum fulvous; elytra bright metallic green, closely and strongly rugose-punctate, 
the interstices longitudinally and also transversely raised, the lateral and apical margins evenly and rather 
broadly fulvous; underside and legs fulvous, 
Hab. Mexico, Acapulco in Guerrero (H6ge). 
The colour of the antenne and the comparatively broad fulvous elytral margin 
chiefly distinguish P. limbata. | 
PROMECOSOMA (p. 131). 
2(4). Promecosoma flohri. (Tab. XL. fig. 25.) 
Oblong, piceous; the lower five joints of the antenne, the head, thorax, and legs rufous; elytra opaque, dull 
greenish, very closely punctured, with three or four obsolete longitudinal costz, the extreme apex dentiform 
and rufous in colour. 
Length 3 lines. 
Head coarsely rugose at the middle, more finely so on the vertex; antenn less than half the length of the 
body, black, the lower five joints rufous; thorax one half broader than long, narrowed in front, the sides 
undulate, and with a flattened margin, the surface irregularly impressed with large and small punctures, 
the interspaces wrinkled at the sides, the disc with a smooth narrow longitudinal space in the middle ; 
scutellum fulvous, its apex truncate; elytra scarcely widened at the middle, opaque, greenish, very closely 
punctured, the interstices finely granulate, but hardly rugose, the sides with two distinct, the dise with 
two very obsolete, longitudinal coste, the extreme lateral margin at the apex rufous, the apex itself 
produced into a tooth ; below nearly black, the sides of the breast and the legs rufous. 
Hiab. Mexico, Refugio in Durango, Durango city (Hége), Maravatio (£lohr). 
This species is perhaps nearest allied to P. dispar; but differs from that insect and 
most of its allies in the elytra being simply punctured (not rugose) and having the 
apex produced. I have received a single specimen from Mr. Flohr, and a dozen others 
were obtained by Herr Hoge; some of these latter have the antenne fulvous, with the 
seventh and apical joints alone fuscous. 
Promecosoma nobilitatum (p. 132). 
To the localities given, add:—Mexico, Chilpancingo and Tepetlapa in Guerrero 
(H. H. Smith). | 
A specimen from Tepetlapa differs from the type in having rufous (instead of 
black) tarsi.
