from Paso Antonio. PP. ustus, Lec., from the Gila river, is, no doubt, an allied 
species. 
23. Peederus pallidus. 
Parvus, gracilis, fulvo-testaceus, abdominis apice nigro, antennis articulis 5°-10™ nigricantibus ; elytris pro- 
thoracis longitudine. 
Long. 6 millim. 
Hab. Guatemaa, Cubilguitz in Vera Paz (Champion). 
This species is closely allied to P. apicalis, but is apparently a rather broader insect, 
with the antennz in large part dark, the elytra shorter and rather more finely punctate. 
We have received only two mutilated examples. 
Subfam. PINOPHILIN AL. 
TANODEMA.

Gymnurus, Nordmann, Symb. p. 158. 
This genus consists of about five-and-twenty species, and is confined to Tropical 
America, with the exception of a single species from Africa added to it by Dr. Gestro. 
When alive, the hind body is very extended, the membranes separating its segments 
being displayed and marked with white at their outer extremities; indeed, in some 
cases, the membrane may be entirely white; these membranes are also beautifully 
sculptured. 
In our region, as elsewhere, these insects are only very rarely met with ; and I have, 
indeed, only eight examples before me, representing at least six species. 
The species are arboreal in their habits (Champion). 
1. Tenodema stigmaticum. (Tab. XVI. fig. 9.) 
Nigrum, nitidum ; capite, prothorace elytrisque viridi-cyaneis; antennis, palpis pedibusque rufis, geniculis 
omnibus tarsisque quatuor posterioribus nigris, antennis extrorsum fuscis; prothorace elytrisque 
irregulariter minus dense punctatis. . 
Long. 23 millim. 
Hab. Guatemana, Sinanja in Vera Paz (Champion). 
Antenne rather long and slender, obscure red; three or four of the penultimate 
joints infuscate at the tip, the terminal joint black; palpi infuscate, red. Head densely 
and coarsely punctate, with a small smooth space on the vertex. Thorax quite as long as 
broad, slightly narrowed in front, the hind angles largely rounded, irregularly punctured 
with a mixture of small and larger punctures, shining. Elytra very elongate, very 
shining, sparingly and feebly punctate. Hind body black, with the membranous borders 
of the segments ornamented with white ; the basal segments with coarse punctuation 
on the basal part of each, the penultimate segments sparingly and finely punctate.
