24 RHYNCHOPHORA. 
2. Aygops vitticollis, (Tab. II. fig. 12, ¢ .) 
Zygops vitticollis, Desbr. Ann. Soc. Ent. Belg. xxxv. p. 39°. 
Hab. Mexico! (Mus. Brit.), Toxpam (Sallé), Cerro de Plumas (//ége) ; GUATEMALA 
Teleman, Chacoj, and San Gerénimo in Vera Paz (Champion); Nicaragua (Sallé), 
Chontales (Belt, Janson); Panama, Volcan de Chiriqui (Champion). 
Found in plenty in the hottest parts of the Polochic Valley in Guatemala. It is 
easily recognizable by its elongate form, the sharply trivittate prothorax, and the 
fulvo-variegate elytra, the under surface whitish, spotted with fuscous along the sides. 
The suture of the elytra is granulate almost to the base. The male has the anterior 
tarsi clothed on each side with long hairs, the first and second ventral segments broadly 
depressed along the middle, and the fifth segment sinuato-truncate at the apex. The 
femora have one or two (the anterior pair sometimes with three) small teeth exterior 
to the larger one. The length varies from 45-93 mm. 
3. Zygops rufomaculata, sp.n. (Tab. II. figg. 13, 134, 2.) 
Elongate-ovate, broad, flattened above, black, the vestiture close and fine; the head with an ochreous line 
around the eyes; the prothorax flavo-cinereous, with a very large carmine-red patch on each side in 
front, which extends downwards on to the flanks, and two black vittee on the disc, these latter connected 
near the base with a curved, sinuous, black stripe extending around the flanks from the lower anterior 
margin; the elytra with the basal half black, with a short curved stripe near the suture at the base, and 
various spots below and exterior to it, flavo-cinereous or fulvous, the apical half alternately lineate with 
fuscous and cinereous ; the pygidium black ; the vestiture of the under surface dense, white, extensively 
maculated with black—a very broad oblique band on the sides of the metasternum extending forwards 
over the mesosternal side-pieces, an oblique stripe on each side of the abdomen, and two stripes down the 
segments 2-5,—that of the legs brownish or cinereous, the femora without darker annuli. Eyes well- 
separated ; rostrum arcuate, tricarinate and deeply quadrisulcate at the base; joint 2 of the funiculus 
more than twice the length of 3, 4-7 submoniliform. Prothorax transverse, strongly bisinuate at the 
base, the sides arcuately converging anteriorly ; densely, minutely punctate. Elytra slightly wider than 
the prothorax, somewhat rounded at the sides, separately rounded at the apex, and arcuately depressed 
below the base ; finely punctate-striate, the strie# sinuous below the base, the alternate interstices wider 
than the others, convex, and sparsely seriato-granulate, 1 conspicuously granulate beyond the middle. 
Legs elongate ; posterior femora bi-, the others uni-dentate. 
Length 95-18, breadth 4-54 millim. ( 9.) 
Hab. Nicaracua, Chontales (Janson).—CotomBiA, Buenaventura (coll. Fry). 
Three specimens. A peculiarly-marked insect, the elytra having the basal and 
apical halves difterently coloured, the prothorax both transversely and longitudinally 
lineate with black, and ornamented with a large carmine-red patch on each side 
in front. Z. rufomaculata is related to Z. mexicana, but in colour it is more like 
Z. rubricollis, Boh. 
4. Zygops erythropyga, sp.n. (Lab. ll. fige. 14, 14a, 2.) 
Oblong-ovate, broad, flattened above, black or piceous, the antenne and sometimes the legs and rostrum in 
part, reddish, the vestiture close and fine; the head with an ochreous ring around the eyes ; the
