Colombia 1. 
Mr. Champion obtained a series of fifteen examples at Bugaba; they show that the 
species is very variable in the colour of the thorax and elytra. The thorax is occasion- 
ally of a dull red colour, and sometimes is of a dark dull eneous colour, the transition 
occurring by a red thorax bimaculate with the darker colour; the elytra are most 
frequently reddish brown, but they become more or less suffused with a dusky eneous 
tint, so that some individuals have them of a fuscous-brassy colour. The punctuation 
and pubescence remain without variation, and the hind body shows less variation in 
colour than the parts before it. 
From each of the other localities there is only a single exponent ; and the Guatemalan 
individual is the most extreme variety obtained, its colour being very dark. Ihave not 
seen any Colombian example of the species. 
3. Philothalpus difficilis. (Tab. VIII. fig. 23.) 
Rufescens; capite thoraceque snescentibus, opacis, antennis (basi excepto) nigricantibus, abdominis segmentis 
tribus ultimis nigro-fasciatis, palpis pedibusque testaceis. 
Var. Elytris, pectore abdominisque basi fuscescentibus. 
Long. 11 millim. 
Hab. Guatemata, San Isidro 1600 feet, El Tumbador 2500 feet, Mirandilla 1700 feet 
(Champion); Nicaraeua, Chontales (Janson). 
This species is extremely closely allied to the two preceding, but has no trace of 
flavescent pubescence on the extremity of the elytra. ‘The scutellum is of an obscure 
red colour, and the elytra are slightly shorter than in P. fasciatus. The sexual 
characters are the same. oo 
Of a series of fifteen examples from Guatemala, one belongs to the dark variety, the 
others are all similar. From Chontales only one example has been obtained. 
4. Philothalpus debilis. 
Rufus; capite thoraceque superne eeneis nitidis, hoc anterius rufo-signato, mesosterno scutelloque fuscis; abdo-
