LOBOPODA. 389 
separated; prothorax very broad at the base, the sides a little sinuate behind and rapidly converging 
from the very acute outwardly directed hind angles, the disc flattened and distinctly canaliculate, the 
basal fovew large and rather deep, the surface very irregularly, rather “coarsely, and somewhat closely 
punctured, a narrow ill-defined longitudinal space on the middle of the disc impunctate; elytra long and 
broad, narrowing from the base, broadly depressed below the scutellum, the base rather deeply impressed 
on each side within the humeri, with rows of fine closely placed punctures which gradually become finer 
towards the apex, the interstices here and there feebly raised in the middle, flat on the basal half of the 
disc, and very sparsely and very irregularly punctured, the punctures on the apical half as coarse as those 
of the strie ; beneath dark bronze, rather closely and somewhat coarsely punctured, a longitudinal space 
on the middle of the metasternum impunctaté; prosternum horizontal, convexly and subacuminately pro- 
duced and received by the deeply excavate mesosternum ; legs and antenne obscure dark bronze, the 
former very thickly pubescent. 
Length 19 millim.; breadth 7 millim. (9.) 
Hab. Mexico, Santecomapan (Sallé). 
A single female example. This species differs from the known forms of Zobopoda in 
the shape of the prosternum; but in its other characters it approaches the first section 
of that genus so closely, more especially to LZ. grandis, that 1 am unwilling to separate 
it in the absence of the male sex. 
2. Prosternum abruptly declivous behind. 
* Upper surface brownish-piceous. 
2. Lobopoda grandis. 
Elongate, very broad, brownish-piceous or piceous, shining, very thickly pubescent. Head coarsely and irre- 
gularly punctured, the punctures here and there confluent on the vertex; eyes (2) moderately large, 
somewhat widely separated; prothorax very broad, not very convex, sinuate at the sides behind, the hind 
angles directed a little outwards though somewhat obtuse, the disc subcanaliculate, broadly but shallowly 
impressed in front, deeply transversely impressed before the base, and with a shallow irregular impression 
on each side about the middle, the basal impression extending on each side to the deep foves, the surface 
coarsely, irregularly, and somewhat closely punctured; elytra broad, gradually narrowing from a little 
below the base, with rows of rather fine punctures placed in broad grooves, the strizw only distinct towards 
the apex, the interstices moderately convex, strongly so beyond the middle, and sparsely and somewhat 
finely punctured ; beneath thickly pubescent, coarsely and rather closely punctured ; mesosternum convex, 
its anterior face abruptly declivous and excavate towards the base only ; legs thickly pubescent and closely 
punctured, brownish-piceous, the tarsi rather short and stout; antenne fusco-ferruginous. 
Length 17-174 millim.; breadth 63-63 millim. ( 2.) 
Hab. Nicaracua, Chontales (Belt, Janson). 
Three female examples. ‘This species, except as regards the structure of the pro- 
sternum, seems to be almost intermediate between Z. gigantea and the typical forms of 
Lobopoda; both are comparatively very broad and large in size. The mesosternum in 
L. grandis is much more convex and has its anterior face more strongly declivous than 
in any of the other species of the genus known to me. The male remains to be 
discovered.
