56 SCYDMANIDA, 
articulated club, each of them longer than broad, the eighth and eleventh joints about 
equal in length, the other two a little shorter. Head very broad in front, short, abruptly 
narrowed behind. Thorax much narrowed in front, its greatest width in front of 
the middle, thence nearly straight, being only very slightly narrowed behind ; the basal 
fovez deep, and there is a third, though obsolete, depression between them. FElytra 
rather broad, with a distinct depression near the shoulders; glabrous, except for a few 
hairs on the humeral portion. Legs rather slender. 
Closely allied to E. calvus, but readily distinguished by the broad thorax, as well as 
by the minute thoracic carinule. Unique. 
25. Euconnus chiriquensis. (Tab. II. fig. 12.) 
Brunneus, elytris rufo-brunneis, pube brevi depressa sat dense vestitus, minus nitidus; antennis clava magna, 
elongata; prothorace subconico, ante basin haud profunde transversim impresso, ad latera utrinque 
breviter subtiliter carinulato. 
Long. 23 millim. 
Hab. Panama, Volcan de Chiriqui between 2500 and 4000 feet (Champion). 
Antenne with joints 3-7 subequal, small; the eighth joint much larger, a good deal 
longer than broad; the ninth and tenth joints each a little shorter and each rather 
longer than broad; the terminal joint acuminate, slightly longer than the eighth. 
Head transverse, but subcircular, the erect pubescence of the vertex very slight; eyes 
rather large, but not convex. Thorax rather large, broader towards the base, its 
pubescence fine and depressed; with a transverse depression, deeper at its termination 
on each side, in front of the base, and external to this a very fine minute carina. 
Elytra depressed at the base, with the shoulders plicate, but the plica very short; their 
pubescence short and depressed. Pectoral lamina remarkably broad, sulcate; middle 
of the metasternum prominent but deplanate. 
26. Kuconnus germanus. (Tab. II. fig. 13.) 
Brunneus, elytris rufo-brunneis, pube brevi depressa vestitus, elytris subopacis; antennis clava magna, elon- 
gata; prothorace subconico, ante basin transversim impresso; elytrorum humeris vix elevatis. 
Long. 2 millim. 
Hab. GuateMALa, Duefias, Capetillo (Champion). 
Allied by the structure of the antenne and the remarkably broad lamina between 
the middle coxe to £. chiriquensis, but smaller and quite distinct by the extremely 
obsolete lateral carinule on the thorax. The head is not all transverse, the thoracic 
depression is scarcely deeper at the sides, and the shoulders of the elytra are almost 
without plication. 
One example from each locality. The thoracic carinule is excessively minute, and 
can only be seen in a quite clean example.
