396 HETEROMERA. 
canaliculate, and a little flattened before the base, the basal fovese moderately deep, the surface rather 
coarsely and somewhat closely punctured; elytra moderately long, very gradually narrowed from the 
base and rather broad behind, with closely punctured rather shallow striz, the interstices feebly convex, 
almost flat on the basal half of the disc, and moderately coarsely punctured ; beneath coarsely but 
sparsely punctured, the metasternum in the middle closely so in the male; legs and antenne brownish- 
ferruginous. 
¢. Anterior tibiee on the inner side angularly widened before the middle, and thence to the apex sinuous. The 
lateral lobes of the last ventral segment rather long and stout, inwardly curved, and a little thickened at 
the apex, the apex bluntly rounded off; the central sheath gradually narrowed behind, the apical portion 
setose beneath, the apex rounded. (Fig. 12.) 
Length 113-11% millim.; breadth 4-42 millim. (3 2.) 
Hab. Mexico, Cordova (Sallé), Jalapa (Hége); Guatemata, Las Mercedes (Champion). 
Three examples. In the comparatively narrowly separated and rather small eyes in 
the male, the very closely punctured vertex, and the somewhat parallel shape, this 
species approaches L. subparallela; but it is easily separated by its smaller size, shorter 
elytra with more finely punctured interstices, more finely punctured thorax, and more 
shining surface, the thorax being also broader and more convex in front. 
14. Lobopoda oblonga. (Tab. XVII. fig. 13.) 
Rather short, brownish-black, shining, sparsely pubescent. Head with the vertex closely, the epistoma 
sparsely, punctured; eyes (¢) comparatively small, somewhat widely separated in both sexes; prothorax 
strongly transverse, transversely convex, widest at the middle, the sides somewhat rounded and usually 
narrowing a little behind, the hind angles rather obtuse, the disc obsoletely canaliculate, the basal foves 
shallow, the surface rather coarsely and somewhat closely punctured on the disc and sparsely so towards 
the sides; elytra subparallel in their basal third, gradually narrowing beyond, with moderately deep 
strie, the striz from the base to the middle closely punctured, the punctures becoming obsolete towards 
the apex, the interstices flat on the disc, feebly convex behind, and each with an irregular row of scattered 
punctures; beneath sparsely and rather coarsely punctured, the middle of the metasternum more closely 
so in the male; legs rather stout, brownish-piceous, the tarsi and the tibie in part more or less ferruginous ; 
antenne fusco-ferruginous. 
3. Anterior tibie subtriangularly widened on the inner side before the middle. The lateral lobes of the last 
ventral segment rather long, inwardly curved, and a little thickened at the apex, the apex bluntly rounded 
off; the central sheath gradually narrowed to the apex, the apex rounded. (Fig. 13.) 
Length 74-10 millim.; breadth 23-33 millim. (¢ 2.) 
Hab. Mexico, Yucatan (coll. F. Bates, Gaumer). 
About fifty examples. This species differs from its allies (except Z. seriata) in the 
thorax being widest at the middle (consequently a little narrowed posteriorly) and 
rounded at the sides. The eyes are rather small and comparatively widely separated 
in the male; and the elytra are subparallel towards the base. JZ. oblonga resembles 
L. convexicollis, but is smaller, less elongate, and has the hind angles of the thorax 
more obtuse, and the interstices of the elytra more thickly and less finely punctured ; 
the cedeagus is very similar to that of Z. convexicollis. 
15. Lobopoda puncticollis. (Tab. XVII. figg. 14, 144, b, 3.) 
Moderately elongate, dark reddish-brown or brownish-piceous, not very shining, thickly pubescent. Head 
rather coarsely and somewhat closely punctured; eyes (¢) very large and approximate; prothorax
