280 PHYTOPHAGA.—SUPPLEMENT. 
2. Iphitroides quadripunctata. (Tab. XLII. fig. 7.) 
‘Flavous, the terminal joints of the antennz fuscous; head and thorax impunctate ; elytra scarcely perceptibly 
punctured, each with a small round spot near the scutellum, and another at the middle, black. 
Length 2-3 lines. 
Hab. Mexico, Chilpancingo in Guerrero (Hoge, H. H. Smith). 
This species only differs from the preceding in the markings of the elytra: the 
anterior spot is placed at the basal margin near the shoulder ; the second spot is equally 
small and placed nearer to the suture, at or immediately below the middle. The 
antenne have the lower four or five joints flavous, the other joints fuscous. Numerous 
specimens. 
3. Iphitroides nigrocincta. (Tab. XLII. fig. 8.) 
Pale testaceous ; the antennz (the basal joint excepted) black, each joint pale at the apex; thorax margined 
with black and with a dark longitudinal stripe on the disc ; elytra scarcely punctured, testaceous, narrowly 
margined with black. 
Length 2-23 lines. 
Hab. Mexico, Chilpancingo in Guerrero (H6ge). 
In shape and structural details this species closely resembles both the preceding. 
The antenne in the male are equally long, and have the basal joint entirely testaceous, 
but all the other joints are of that colour at the apex only. The thorax is impunctate, 
narrowly margined with black, and has a black median vitta, the latter in one 
specimen extending only as far as the sulcus. The scutellum is black. The elytra 
are exceedingly finely punctured, of a pale testaceous colour, and are narrowly margined 
with black. The tibize are stained with fuscous at the base; the other parts of the 
legs, as well as the underside, are testaceous. ‘Two specimens. 
4, Iphitroides violaceipennis. 
Fulvous ; the antenne (the basal three joints excepted) black ; head and thorax impunctate ; elytra violaceous- 
blue, extremely minutely punctured ; legs fulvous; abdomen piceous, 
Length 24 lines. | 
Hab. Mexico (coll. Duvivier). 
I. violaceipennis differs from the other species of the genus by the transverse sulcus 
of the thorax being almost obsolete; the longitudinal grooves at the sides of the 
thorax, however, are very distinct. ‘The elytra are violaceous-blue in colour; the head 
and thorax are entirely impunctate; the antenne extend almost to the end of the 
elytra, and are black, with the exception of the first three joints, these being fulvous ; 
the posterior femora are scarcely thicker than the others. 
The only specimen I have seen of this species was kindly given to me for description 
by M. Duvivier.
