CALLIPHRON.—IPHITROIDES. 279 
3. Head impunctate, the frontal elevations strongly raised, transverse, bounded behind by a deep transverse 
groove, the carina short; palpi rather robust, the terminal joint acute; antenne nearly black, thickly 
pubescent, two-thirds the length of the body, the third and following joints nearly equal; thorax trans- 
versely convex, about twice as broad as long, the sides rounded, all the angles obsolete, the disc with a 
few punctures only near the base; scutellum broad, its apex rounded ; elytra parallel, without any basal 
depression, each with nine not very regular but distinct rows of punctures; underside fulvous ; legs 
black. 
Hab. Panama, Volcan de Chiriqui (Champion). 
In the female the antenne are much shorter, the terminal joints particularly so ; 
in the male joints 3-5 are more elongate than the others, and the third and fourth are 
thickened at their apex. Many specimens. 
IPHITROIDES. (To follow the genus Prasona, p. 322.) 
Elongate, parallel; antenns filiform, slender; thorax subquadrate, narrowed at the base, the disc with a 
transverse sulcus, terminated at the sides by a longitudinal groove; elytra glabrous, finely punctured, 
their epipleure broad at the base and continued to the apex ; legs slender, the posterior femora but feebly 
dilated ; posterior tibie with a small spine, not channelled ; the first joint of the posterior tarsi as long 
as the following three joints together; claws appendiculate; prosternum narrow ; anterior coxal cavities 
closed. 
This genus is proposed to include some elongate species which somewhat resemble 
Iphitrea, Baly, in the form of the thorax; but differ from it by the non-pubescent 
upper surface and the appendiculate claws. The posterior femora are only feebly 
dilated; but the general facies, the sulcate thorax, the broad elytral epipleure, and the 
distinct prosternum are characteristic of the group Halticine. 
1. Iphitroides quadrimaculata. (Tab. XLII. fig. 6.) 
Pale fulvous ; the antennz nearly as long as the body ; head and thorax impunctate ; elytra very finely and 
closely punctured, a rounded spot at the shoulders, and a more elongate one near the apex, piceous. 
‘Length 2-24 lines. 
Head impunctate, broader than long, the eyes very large and prominent, the frontal elevations narrowly 
elongate; palpi rather robust, the terminal joint very short, acute; antenne extending to rather more 
than two-thirds the length of the elytra, fulvous, the first joint elongate and thickened, the second less 
than half the length of the first, the fourth joint longer than the third; thorax not broader than long, 
narrowed at the base, the angles not produced but distinct, the base with a distinct transverse sulcus 
bounded at the sides by a longitudinal groove, the surface impunctate, fulvous; scutellum rather long, its 
apex broadly rounded ; elytra much wider at the base than the thorax, parallel, the surface rather flat- 
tened, extremely closely and finely punctured, with traces of feebly raised longitudinal lines, fulvous or 
flavous, each elytron with a rounded piceous spot at the shoulder, and a more elongate one near the 
apex, these spots not extending to either margin; underside and legs pale fulvous; the last abdominal 
segment of the male produced into a rounded lobe, and the preceding segment with a longitudinal 
median groove. 
Hab. Mexico, Ventanas in Durango (Hége). 
Numerous examples.
