46 PSELAPHID&.—SCYDMENIDZA. 
1. Endytocera vestita. (Tab. I. fig. 25.) 
Brunnea, elytris rufescentibus, omnino densissime flavo-pubescens ; prothorace lateribus pone medium subito 
constrictis, prominulis, dorso pone medium depressione magna glabra. 
Long. 34 millim. 
flab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Antenne rather long, densely pubescent, the apex not thicker than the middle. 
Head elongate, a little constricted in front of the eyes, evenly convex, without 
depressions, exceedingly densely pubescent. Thorax transverse, the sides abruptly 
constricted so as to leave a prominent angle a little behind the middle; the surface very 
densely punctate and pubescent, except ona large transverse depression behind the 
middle ; on each side, scarcely connected with the median depression, is a smaller 
depression. The elytra are large, with a deep sutural stria, and obscure traces at the 
base of the false basal margin seen in many Pselaphide. The legs are slender, the 
hind tarsi elongate and slender. One example. 
2. Endytocera cognata. 
Piceo-brunnea, elytris piceo-rufis, densissime subtiliter pubescens, subopaca ; prothorace brevi, lateribus pone 
medium constrictis, minus acute angulatis, ante basin transversim depresso. 
Long. 3} millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Head with an obscure depression on either side much concealed by pubescence ; 
vertex foveolate. Thorax strongly transverse, very finely and minutely punctate, 
shining though closely and finely pubescent; with a curved transverse impression in 
front of the base, and near it on either side a very large foveiform depression. Elytra 
elongate, with a sutural stria, and between it and the shoulder a very fine but elongate 
plica. First dorsal segment not at all longer than the second. 
This insect also is unique; though similar at first sight to HZ. vestita it is abundantly 
distinct. The individual is probably a female. 
Fam. SCYDMANIDA*. 
We have received only very few individuals of this family from Mexico, our material 
in fact being almost exclusively the results of Mr. Champion’s collecting in Guatemala 
and the State of Panama. As no Scydmenide have hitherto been described from any 
part of our region, except Mexico, it is not a matter of surprise that so large a propor- 
tion of our acquisitions in this family are new. As the genera are so few in number, it 
is unnecessary for the purposes of this work to make use of any subdivision of the 
family.
