LOBOPODA. 395 
sheath almost parallel, very slightly narrowed immediately before the apex, the apical portion finely 
setose beneath and a little recurved, the apex itself subtriangular. (Fig. 10.) 
Length 124-141 millim.; breadth 4-5 millim. (¢.) 
Hab. Mexico, Yolos (Sallé), Jalapa, Cuernavaca, Tehuantepec (Hége). 
Four examples, all males, one from each locality. The very closely and coarsely 
punctured vertex, the closely and coarsely punctured thorax, the sides of which are 
straight behind, and the long and subparallel elytra sufficiently distinguish L. swd- 
parallela from the allied forms. The four examples differ a little inter se; in one 
specimen the eyes are more widely separated, and the interstices of the elytra are rather 
more closely punctured, but I have no doubt that such variation is due to local causes. 
L. subparallela is of about the size and shape of L. pallicornis (Fabr.), from Buenos 
Ayres, but has the upper surface much more coarsely punctured. 
12. Lobopoda seriata. (Tab. XVII. figg. 11, 11 @.) 
Elongate, black, slightly shining, sparsely pubescent. Head very sparsely punctured; eyes very large and 
approximate in the male, much smaller and rather widely separated in the female ; prothorax transversely 
convex, the sides from the middle to the base straight or a little rounded and narrowed, the disc canali- 
culate, and sometimes with a very shallow fovea on each side about the middle, the basal fovere deep and 
connected by a transverse depression, the hind angles obtuse, the surface with widely scattered moderately 
fine punctures ; elytra long, narrowing from a little below the base, with rows of coarse punctures placed 
upon rather shallow striae, the punctures towards the apex much more scattered and elongate in shape, 
the interstices very feebly convex or almost flat and very sparsely punctured; beneath very sparsely and 
rather coarsely punctured, the metasternum in both sexes with widely scattered punctures ; legs brownish- 
piceous, the tarsi and antenne more or less ferruginous. 
g. Anterior tibie triangularly widened on the inner side before the middle; anterior femora with a short 
median tooth. ‘The lateral lobes of the last ventral segment broad, trifurcate, the central lobe oblique, and 
with its apex truncate and furnished with a long fringe of hairs, the inner lobe narrow and slightly 
recurved and rounded at the apex; the central sheath broad, rounded at the apex. (Figg. 11, 11a.) 
Length 103-13} millim.; breadth 34-42 millim. (¢ 2.) 
Hab. Mexico, Temax in N. Yucatan (Gawmer). 
We have quite recently received a large number of examples of this species from 
Mr. Gaumer. 
L. seriata closely resembles L. apicalis in the structure of the lateral lobes of the 
last ventral segment in the male (differing only in the more angular lateral extension) 
and in the elytral sculpture ; it differs greatly, however, in the shape of the thorax, and 
in this respect more nearly resembles L. convexicollis and L. oblonga. 
Well-developed males have the anterior tibie more strongly triangularly widened 
within. 
13. Lobopoda convexicollis, (Tab. XVII. fig. 12.) 
Moderately elongate, brownish-piceous, shining, somewhat thickly pubescent. Head with the vertex very 
closely, the epistoma rather sparsely, punctured; eyes only moderately large and somewhat widely 
separated in the male, more distant in the female; prothorax rather broad and convex in front, the 
sides almost straight from the middle to the base, the hind angles subrectangular, the disc obsoletely
