LOBOPODA. . 399 
spoon-shaped, though abruptly narrowing and slightly acuminate behind, the apex a little widened and 
bluntly rounded. (Fig. 18 a.) 
Length 83-91 millim.; breadth 33-4 millim. (¢ 2.) 
Hab. Mexico, Tapachula in Chiapas, Frontera in Tabasco (Hége); Guatemata, San 
Isidro, Volcan de Atitlan (Champion) ; Panama, Bugaba, Caldera in Chiriqui (Champion). 
Many examples. This species may be known by its dull surface, very slender 
antenne in the male, distinctly canaliculate thorax, comparatively short broad form, 
dark knees, and the very peculiar structure of the cedeagus. In two examples the 
femora and the greater part of the tibiz are dark in colour. 
20. Lobopoda chontalensis. 
Moderately elongate, rather broad, piceous-black, slightly shining, thickly pubescent. Head with scattered 
shallow punctures; eyes () moderately large and rather narrowly separated; prothorax closely and 
rather coarsely punctured, the sides slightly sinuate behind, the hind angles subrectangular, the disc 
shallowly impressed before the base and obsoletely canaliculate, the basal fovese rather shallow; elytra 
broad in front, rapidly narrowing behind, rather deeply striate, the strie to beyond the middle with very 
coarse punctures and thence to the apex with finer impressions, the interstices slightly convex and rather 
coarsely punctured; beneath sparsely but rather coarsely punctured; legs fusco-ferruginous, the tarsi 
lighter ; antenne ferruginous. 
Length 10-114 millim.; breadth 32-4 millim. (@.) 
Hab. Nicaracua, Chontales (Belt). 
Two female examples. ‘his insect resembles the dark-legged form of L. femoralis ; 
it differs in being larger and broader, and in having the elytral strie very much more 
coarsely punctured and the antenne stouter. 
21. Lobopoda simplex. (Tab. XVII. fig. 22.) 
Rather short, reddish-brown or brownish-piceous, shining, thickly pubescent. Head with scattered, shallow, 
rather coarse punctures; eyes large and approximate in the male, smaller and somewhat widely separated 
in the female; prothorax broad, convex, the disc a little flattened before the base, the basal foveze small 
and shallow, the surface very shining and rather closely and somewhat coarsely punctured; elytra rather 
short, a little rounded at the sides, with closely and rather coarsely punctured striz, the interstices feebly 
convex and finely punctured; beneath sparsely but rather coarsely punctured; legs and antenne 
ferruginous. 
¢. Anterior tibie sinuous on the inner side. The lateral lobes of the last ventral segment long and slender, 
very narrow, slightly curved inwards, and a little thickened at the apex; the central sheath narrow, 
gradually narrowing behind, the apex bluntly rounded. (Fig. 22.) 
Length 9 millim.; breadth 3} millim. (d 9.) 
Hab. Britisn Honpuras, Belize (Blancaneauz). 
Three examples. The short form, the convex, non-canaliculate, and very shining 
thorax, and the simple structure of the cedeagus distinguish this species from others of 
the genus; L. simplex is perhaps nearest allied to ZL. tropicalis. A single female 
example from Yucatan (Gawmer) is perhaps referable to this species; it differs from 
the others in having the thorax more sparsely punctured and distinctly canaliculate, 
and in the elytra being less convex.
