a24 HETEROMERA. 
Var. Smaller, narrower, and more parallel, the tooth on the tibie in the male smaller. 
Length 43-5 millim. (¢ 2.) 
Hab. Mexico, Cordova, Jalapa (Hoge); Bririsa Hoypuras, R. Hondo (Blancaneaux). 
Apparently a common insect in the above-mentioned localities. 7’. lecontet resembles 
T. neotropicalis in general facies and in the sculpture of the upper surface, but is 
only about half the size, and has the antenne relatively shorter, not so stout, and with 
the apical joint less elongate ; the elytra shorter; the posterior tibiz in the male armed 
with a single sharp tooth (like that on the other tibie), which is placed not very far from 
the apex (in 7. neotropicalis the two comparatively smaller teeth are placed nearer the 
middle). 
The variety is connected with the type by intermediate forms, though at first sight 
appearing distinct. 
Dignamptus langurinus, Lec., from Florida, to judge from the description, is an ally 
of this species. 
T’. lecontei is apparently confined to the Atlantic slope. 
5. Talanus interstitialis. 
Allied to 7. lecontei, and differing as follows :—the prothorax more strongly sinuate at the sides behind; the 
impressions on the apical portion of the elytra deeper (not becoming quite so fine or shallow behind as in 
T’. leconter), the interstices slightly but distinctly convex towards the apex; the tibiw in the male (the 
middle pair especially) more curved, each armed with a small triangular tooth on the inner side imme- 
diately before the apex; the rest as in 7’. lecontet. 
Length 5-63 millim. (¢ 9.) 
Hab. Muxico, Tapachula in Chiapas (Hége); Guatemata, El Tumbador, El Reposo, 
Paraiso, Las Mercedes, Pantaleon, Zapote (Champion). 
Many specimens. This insect is sufficiently distinguished from 7. lecontei by the 
different male characters (the tooth on the inner side of the tibize being placed much 
nearer the apex), and the convex interstices at the apex of the elytra. 
T. interstitialis seems to replace T. lecontei on the Pacific slope. 
6. Talanus colombianus. 
Talanus columbianus, Makl. Qifv. Finsk. Vetensk.-Soc. Férh. xx. p. 99}. 
Var. Smaller, narrower, and more elongate ; the elytral impressions closer and deeper. (¢.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).—CotomBIa |, 
Five examples, four males and one female, of a Talanus from the State of Panama 
are apparently referable to this species. These specimens differ from 7’. lecontei as 
follows :—The thorax is more rounded at the sides anteriorly, more constricted behind, 
and the transverse impression before the base is deeper; and the elytra are less 
parallel, and the impressions are shallower, finer, and not quite so closely placed.
