prothorax transverse, convex, sides almost straight behind near the base, rounded and narrowed in front, 
hind angles rectangular, front angles slightly pointed and a little prominent, base strongly bisinuate and 
with a short feeble shallow oblique impression on each side and rarely a slight impression in the centre in 
front of the scutellum, anterior margin emarginate and sinuate on each side near the angles just behind 
the eyes, rather coarsely and closely punctured along the sides, more sparingly and finely in the middle ; 
elytra with regular rows of coarse punctures distinct to the apex, the interstices with scattered fine punc- 
tures; intercoxal process long, acuminate at the apex, and passing beyond the hind coxe; metasternum 
long; mandibles toothed on the upperside; legs and antenne red. 
Length 7-8 millim. 
Hab. Panama, Volcan de Chiriqui, Tolé, Taboga Island (Champion).—CoLomB1a, 
Bogota (coll. Bates). 
Rather common in Chiriqui at an elevation of from 2000 to 4000 feet, and found by 
beating herbage. 
3. Emmenastus longicornis. 
Winged, elongate oval, black, shining. Head with two feeble impressions between the eyes, the front rather 
coarsely and closely, the vertex a little more sparingly punctured; prothorax transverse, convex, rounded 
at the sides, a little narrower in front than behind, base strongly bisinuate, coarsely and closely and almost 
equally punctured, a little more sparingly punctured in the middle behind, slightly impressed transversely 
in front of the scutellum; elytra long, almost parallel to beyond the middle, with regular rows of coarse 
punctures distinct to the apex, the interstices with exceedingly fine scattered punctures; antenne and legs 
dark reddish brown, the former rather long. 
Length 8 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
One example. Allied to E. chiriquensis, but narrower, the thorax more coarsely 
punctured and more narrowed behind, and the antenne a little longer. 
reddish brown in colour, slightly shining; the head closely and rather coarsely punctured; prothorax convex, 
rounded at the sides, narrowed in front, the sides very feebly sinuate before the rather acute anterior angles, a 
little narrowed behind, hind angles obtuse, base bisinuate, finely and closely punctured, the punctures confluent 
at the sides, a small rounded impression behind in front of the scutellum; elytra convex, a little wider than the 
thorax at the base, with indistinct but regular rows of fine punctures to the apex; interstices finely and rather 
closely punctured. Length 53 millim. One specimen in Mr. F. Bates’s collection, labelled: Calif. ex coll. 
Laferte.
