is shining ; both sexes have a well-marked opalescent shimmer on the elytra, and the 
sutural stria is deep and distinct. The colour, no doubt, varies a good deal, but the 
extensive infuscation of the middle of the thorax is always present in our examples. 
8. Pallodes regularis, sp. n. 
Oblongo-ovalis, convexus, sordide testaceus, antennarum clava nigricante ; elytris evidentius seriatim punc- 
tatis, interstitiis parce obsoleteque punctatis. 
Long. 43 millim. 
Had. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith); Guatemata, San 
Gerénimo (Champion). 
Antenne with broad club, which is of blackish colour. Head rather closely and 
finely punctate. Thorax and scutellum almost impunctate. LElytra with series of quite 
definite and distinct punctures, and with a fine and distant interstitial punctuation. 
Pygidium closely punctate. 
Three female examples have been obtained of this species; the distinct serial punc- 
tuation of the elytra distinguishes it from P. micans and P. deletus. It differs from 
P. silaceus by the dark club of the antennz, and also is of rather more oblong form, 
with the interstitial punctuation of the elytra less obsolete. 
9. Pallodes cercyonoides, sp. n. 
Ovalis, convexus, piceus, elytris nigris, antennis pedibusque rufis, illarum clava nigra; prothorace crebrius 
subtiliter punctato ; elytris subtiliter seriatim punctatis, interstitiis fere impunctatis. 
Long. 33-4 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Antenne with broad, rather short, black club, the apical joint of which is shorter 
and more rounded than usual. Head and thorax closely and finely punctate. Scu- 
tellum almost impunctate. Elytra with regular series of fine punctures, with scarcely — 
any interstitial punctuation. Under surface piceous-red. 
This insect resembles P. mexicanus, but is of darker colour beneath ; has the thorax 
more closely punctate and the club of the antenne shorter. Four specimens have been 
obtained. The male differs very little from the female.

Rotundato-ovalis, sat convexus, testaceo-albidus, elytris fusco-signatis, antennarum clava nigricante, tarsis 
fuscescentibus ; elytris parce, irregulariter, sat fortiter punctatis.

Club of the antenne large, black. Head fuscescent-yellow. Thorax pale yellow, vaguely 
fuscescent on the middle, rather coarsely but not closely punctured. Elytra pale yellow,
