elytra. The fifth ventral segment is flattened in both sexes. The hairs vary in length 
and are sometimes more closely placed and longer in the variety than in the type. 
I have seen the specimens described by Boheman from the collections of Sturm and 
Sommer. 
2. Megalostylus tomentosus, sp. n. (Tab. X. fig. 24, ¢.) 
Oblong, piceous, the deciduous mandibles and legs ferruginous ; densely clothed above and beneath with 
metallic golden-green scales, and also thickly clothed with long, pallid, erect hairs. Rostrum broadly 
excavate from the apex to near the eyes, the latter rounded, convex, and very prominent in ¢ ; antenne 
with the scape greatly thickened towards the apex and extending to beyond the eyes in ¢g, shorter 
and more slender in 9, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, 
conical, feebly bisinuate at the base, the hind angles acute. Scutellum triangular. Elytra considerably 
wider at the base than the prothorax, gradually narrowing from the shoulders in ¢, subparallel in 
their basal half in 9, finely punctate-striate, the interstices flat. First ventral segment broadly 
hollowed down the middle in ¢, the fifth flattened in both sexes. 
Length 7-71, breadth 2} millim. (¢ 2.) 
Hab. Mexico, Yolotepec in Oaxaca (Sallé: g), Jalapa? (fHége: 2). 
One pair. This insect is very like the green forms of M. splendidus and M. albicans, 
but it is as hairy as VW. sturmi. Possibly there is a cinereo-squamose variety of it? 
3. Megalostylus rhodopus. (Tab. X. fig. 25, ¢ .) 
Megalostylus rhodopus, Boh. in Schénh. Gen. Cure. vi. 1, p. 116 ‘, 
Length 43-10, breadth 2-4 millim. 
Hab. Mexico (coll. Sommer), Cordova, Jalapa (Hége), Oaxaca (Mus. Brit., Salié). 
This species may be known by its not very densely squamose surface; the red legs; 
the conical prothorax, with the base feebly sinuate, and the hind angles acutely 
extending outwards in both sexes; the rather large scutellum ; the posteriorly setose 
suture of the elytra, the elytra themselves broader than the prothorax, and somewhat 
depressed in the female; and the hairy under surface and legs. ‘The scales on the 
upper surface vary in colour—greenish, bluish, olivaceous, or cinereous, those on 
the scutellum and the sides of the body beneath whitish. ‘The first ventral segment 
is hollowed down the middle in the male. J/. rhodopus is apparently a common 
insect in Oaxaca. I have seen the types belonging to the Sommer collection. 
4, Megalostylus brevipilis, sp.n. (Tab. X. fig. 26, ¢.) 
3. Oblong, robust, subfusiform, black, densely clothed with whitish or greenish-white scales, and also set 
with short, fine, decumbent hairs, those on the elytra uniseriately arranged down each interstice, the 
legs with longer hairs. Rostrum broadly excavate anteriorly; antennal scape strongly clavate, slender 
at the base, reaching to just bey ond the eyes, the latter rounded and very prominent. Prothorax 
transverse, conical, the hind angles acutely directed outwards, the base moderately bisinuate. Scutellum 
small, Elytra broader than the prothorax, narrowing from the humeri, finely punetate-striate, the
