210 HEMIPTERA-HETEROPTERA. 
females seen appear to have the head, pronotum, and under surface more thickly pilose 
than the males, the pronotum more rugose, more constricted at the sides, and with the 
anterior lobe somewhat gibbous. Prof. Uhler records ?, from California, a black variety, 
with the outer edge only of the abdomen red, The larva has the tarsi 2-jointed. We 
figure a male and a larva, both from Ventanas. 
2. Meccus pallidipennis. (Tab. XII. figg. 24, 24a, 2.) 
Meccus pallidipennis, Stal, Enum. Hemipt. ii. p. 110 (¢) (1872) *. 
Hab. Mexico! (Mus. Holm.!: ¢; Mus. Brit.: 2), Chilpancingo in Guerrero 
4600 feet (H. H. Smith: @ ). 
Of this fine species we have received a female example from Western Mexico; it 
measures 35 millim. in length, and 163 millim. in breadth, and is therefore much 
larger than St&l’s type (length 30, breadth 13} millim.), The coloration of the elytra 
is very like that of Hammatocerus purcis (Drury) and H. luctuosus, Stal, the base being 
very broadly banded with whitish. 
8. Meccus mexicanus.

This species, which appears to have been known to Stal from description only, is 
evidently a close ally of MW. phyllosoma, but differs from it in having the hind angles of 
the pronotum acute and the outer margins of the corium ochreous. We have received 
a larva of a Meccus from Yucatan (Gaumer) which may belong to it. 
LAMUS. 
Lamus, Stal, Berl. ent. Zeitschr. iii. p. 115 (1859) ; Hemipt. Fabr. i. p. 123; Enum. Hemipt. 11. 
pp. 109, 112. 
The two Tropical South-American species referred to this genus by Stal differ from 
Conorrhinus in having the antenne inserted very near the eyes (the portion of the head 
in front of this point being three or four times as long as the antenniferous processes). 
The Central-American species now added is intermediate in this respect, as are 
Conorrhinus lignarius, Walk., and C. porrigens, Walk., which are nearly allied 
congeneric forms. 
1. Lamus rufotuberculatus, n. sp. (Tab. XII. figg. 27, 27 a, 6.) 
3. Elongate, opaque above, black, sparsely clothed with very short decumbent pallid hairs; the head with 
the raised central portion of the anterior lobe, the sides of the posterior lobe, and a Y-shaped mark on its 
disc, rufo-ferruginous ; the pronotum with the anterior angles, and the tubercles and several sinuous lines 
on the disc of the anterior lobe, bright red, and the hind angles, a spot on each side of the disc near them, 
a short longitudinal inark in the centre at the base, and two patches on the disc of the posterior lobe in
