punctures. Scutellum with a fine median carina. Meso- and metasternal carine prominent, the carinze 
continued on to the first ventral segment. 
g. Intermediate femora armed with a short tooth near the base ; second and third ventral segments flattened 
in the middle. 
Length 2;1,-24 millim. (d¢ 9.) 
Hab. Panama, Bugaba and Caldera in Chiriqui (Champion). 
Three males and two females. This species may be known by the deeply, longi- 
tudinally sulcate disc of the pronotum, in connection with the long basal joint of the 
antenne, the rather elongate body, &c. The apical two joints of the antenne are 
together much longer than the third. The rostral groove is limited on each side by a 
prominent ridge, which is continued on to the first ventral segment. 
7. Hebrus concinnus.

Six specimens, agreeing with Uhler’s types in the British Museum. AH. concinnus 
appears to be a common species in the Atlantic States of North America, occurring 
also in California. Apterous individuals are noticed by Prof. Uhler.

The three Central-American species referred to this genus differ from Hebrus in 
having the antenne 4-jointed*, 7.e. the fourth and fifth joints are fused into one, 
without trace of a suture between them. In J. hebroides, the type of the genus 
Merragata, the joints 1-3 of the antenne are subequal in length; the other two 
species have an elongate third joint. The tarsi are 2-jointed f.

Antennz with joint 3 slender and very much longer than 2, 4 slender and

Elytra with a pallid or whitish evanescent mark on the clavus and a pale 
streak on the corium; pronotum moderately constricted at the sides. brevis, n. sp. 
* Buchanan White describes the antenne as 5-jointed, he counting the minute jointlet at the base of 
the third joint as a true joint. 
+ Berg describes the posterior tarsi as 3-jointed, but this cannot be correct.
