above generic form, the characters of which'are clearly given by Guérin in the specific 
description of Brachycoryna pumila, the species on which it was founded by that author. 
Von Harold (Mun. Catal.) subsequently placed the insects in Octotoma, a genus with 
which, the structure of the antenne excepted, it has no affinity. 
Since the earlier part of this work was published, I have, through the kindness of 
Dr. Horn, received a specimen of Stenopodius flavidus of that author. It belongs to 
the present section of the family, and stands close to Brachycoryna. It agrees with 
that genus in possessing very short antenne, but differs in the produced anterior margin 
of the thorax, and in the greater number of punctate-strie on its elytra. S. flavidus 
is a native of California, and will probably, sooner or later, be found in Central 
America.

Guérin, in his description of the species, gives the elytra as unicolorous. In all the 
specimens that I have seen they are more or less spotted with piceous or black. 
2. Brachycoryna fulvipes. 
Anguste oblonga, convexa, subnitida ; subtus nitida ; pedibus elytrorumque puncto prope suturam posito, fulvis ; 
thorace rugoso-punctato ; elytris tricostatis, costis exterioribus duabus late interruptis, interspatiis fortiter 
. biseriato-punctatis. 
Long. 1 lin.. 
Hab. Panama, Tolé (Champion). 
Vertex granulose, impressed on the medial line with a deep longitudinal fovea. 
Antenne rather shorter than the head and thorax; joints cylindrical, gradually 
increasing in thickness from the third to the sixth;. this last nearly as long as the 
preceding two united, and together with the five upper joints, which are closely united, 
forming an oblong acute club. Thorax scarcely longer than broad; sides slightly 
rounded, parallel at the base, converging towards the apex; upper surface subcylin- 
drical, granulose, coarsely and closely punctured, the medial line with a longitudinal, 
groove. FElytra oblong, parallel, regularly rounded at the apex, the outer margin finely , 
serrulate; above convex, each elytron with three strongly elevated coste, the inner one, 
which is interrupted below the basilar space, terminating some distance before reaching 
the apical margin, its apex curving abruptly outwards, and the outer two, which are _ 
shorter than the preceding one, interrupted for the greater part of their course, their 
apices being confluent and abruptly elevated; spaces between the coste each with a 
double row of large deep punctures; on the inner costa, near its middle, i is a small 
fulvous spot.
