80 - HETEROMERA. 
5. Eustrophopsis bipunctatus. (Tab. IV. fig. 8, var.) 
Ovate, moderately broad, flavous or testaceous, the elytra each with a transverse black spot on the disc before 
the middle, this spot sometimes largely and obliquely extended inwardly and also posteriorly (in one 
example confluent with the opposite one at the suture and forming a large common postmedian patch), 
the surface shining and densely clothed with yellowish pubescence. Antenne with joints 1-5 and the 
outer half of the apical one testaceous, the rest black, 5-11 moderately dilated; eyes very large and 
approximate; prothorax very finely and shallowly punctured, the basal fovex indistinctly indicated ; 
elytra very finely striate-punctate, the punctures not distinct to the apex, the interstices closely and 
finely punctured ; beneath reddish-testaceous, closely and finely punctured; prosternum parallel between 
the coxe, the apex rather deeply emarginate ; legs testaceous. 
Length 6-63 millim.; breadth 33-33 millim. 
Hab. Mexico, Cordova (Sallé) ; Nicaracua, Chontales (Belt). 
In the serial rows of punctures on the elytra being confused with the punctures of 
the interstices towards the apex and in the coloration of the antenne this species 
resembles H. discoitdeus; it may be distinguished from it, however, by its less convex 
shape and the different system of coloration of the upper surface. The spot on the 
disc of each elytron varies exceedingly in size in the five examples under examination ; 
in two of them it is quite small. An undescribed species from the Amazons only 
differs from . bipunctatus in having the serial rows of punctures on the elytra 
completely obliterated. 
ORCHESIA. 
Orchesia, Latreille, Gen. Crust. et Ins. ii. p. 159 (1807); Lacordaire, Gen. Col. v. p. 542; Horn, 
Trans. Am. Ent. Soc. xv. p. 37. 
Clinocara, Thomson, Skand. Col. vi. p. 306 (1864). 
Numerous species of this genus have been described from Europe, North America, 
Chili, and Australia. O. 15-maculata, Casteln., as already stated, is referable to Eus- 
trophopsis. One is here recorded from Guatemala, this being the only true Orchesia 
known as yet from the tropical zone *; the genus is doubtless represented in Mexico. 
The exceedingly long spurs to the hind tibie, of equal length and pectinate beneath, 
are very characteristic. 
1. Orchesia guatemalensis. (Tab. IV. fig. 9.) 
Elongate, strongly narrowed posteriorly, brown, castaneous, or fulvo-castaneous, thickly clothed with rather 
coarse brownish pubescence. Eyes very narrowly separated; antenne slender, comparatively long, 
gradually widening outwardly, the penultimate joints longer than broad, ferruginous or testaceous : 
prothorax densely and very finely punctured, the punctuation coarser at the base, the basal fovee only 
indistinctly indicated; elytra narrowing from a little below the base, very finely, densely, and somewhat 
roughly punctured, the punctuation coarser at the extreme base and finer towards the apex; beneath with 
the sides and side-pieces of the metasternum densely and roughly punctured, the venter very densely and 
* The Orchesia (Mycetophagus) janus, Fabr., from Brazil, of Gemminger and Harold’s Catalogue, vii. p. 2064, 
is a Platydema, and is, indeed, entered in the same catalogue in its proper place on p. 1952.
