Long. 7 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Head shining brassy above, covered with very coarse punctures. Thorax covered 
with very coarse punctures, which leave at the base and at the front margin small 
spaces along the middle between them smooth. Elytra densely and rather. coarsely 
punctate, the punctuation at the hind margin more scanty and finer ; black, with an 
obscure brassy tinge, the base rather broadly red. Hind body with the two penulti- 
mate segments in greater part black, the apical segment yellow, its hind margin and 
the terminal styles infuscate. Underside of the head shining, with numerous coarse 
punctures. 
Five examples of this remarkably sculptured species were met with. The male 
scarcely differs from the female externally. 
28. Peederomimus perforatus. 
Rufus; capite, metasterno abdomineque ante apicem nigris; capite superne enescente; elytris (basi excepta) 
nigricantibus; thorace rufo-eneo; antennis in medio nigricantibus ; pedibus testaceis, tibiis apicem versus 
fuscescentibus ; capite thoraceque dense grosse punctatis. 
Long. 8 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Head very shining, brassy above, covered with very coarse punctures, leaving a 
considerable space along the middle in front smooth. Thorax red, but deeply tinctured 
with brassy; with very numerous coarse punctures, which do not extend to the base, the 
punctures of the two sides of the thorax remain distinct, and not meeting on the middle 
except just on the disc. Elytra brassy black, rather broadly red at the base, somewhat 
closely and moderately coarsely punctate. Head beneath shining, with only a few 
fine punctures. 
A single, decayed example is the only one that has been captured: though allied to 
P. cribratus this species has numerous good points of distinction, the most striking of 
them being the finely and sparingly punctate underside of the head. 
29. Pederomimus corrosus, (Tab. XI. fig. 25.) 
Fulvus; capite thoraceque rufo-fulvis, illo interdum superne enescente ; elytris (basi excepta) fusco-subeneis ; 
antennis testaceis, medio enescentibus; pedibus albido-testaceis, femoribus extrorsum abdomineque ante 
apicem fuscescentibus ; capite thoraceque omnium densius grosseque punctatis. 
Long. 6} millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Antenne rather slender and elongate. Head, except on its front margin between 
the antenne, entirely covered above with very large closely placed punctures. Thorax 
with its very coarse punctuation even denser than that upon the head, so that many of
