ELAODES. 87 
b. Elytra rounded at the apex. 
33. Eleodes erratica. (Tab. IV. fig. 16, 3.) 
Oblong ovate, convex, dull black. Head nearly smooth, or with fine scattered punctures ; prothorax about as 
broad as long (male), a little shorter and more transverse (female), strongly convex, rounded at the sides, 
the base and apex of equal width, widest in the middle, in some examples very feebly sinuate near the 
obtuse anterior angles, hind angles obtuse or indistinct, with exceedingly fine scattered punctures; elytra 
narrow in the male, broader in the female, convex, the sides rounded to the base, widest about the 
middle, humeri obtuse, finely punctate-striate, the interstices each with a row of much finer punctures 
(often obsolete), in some examples the punctures of the strie are indistinct and almost obsolete; 
anterior femora in the male with a short tooth, in the female bluntly toothed; antenne in the male 
long and thin, in the female shorter and stouter, the last three joints in both sexes distinctly broader 
and larger than the preceding; basal joints of the anterior tarsi in the male thickly clothed with hair 
beneath; anterior tibial spurs subequal; legs in the male longer and thinner than in the female; pro- 
sternum with a more or less distinct blunt tooth behind. 
Length 93-14 millim. (¢ 9.) 
Hab. Mexico, San Blas, Mazatlan, Presidio, Tres Marias Islands (Forrer). 
Twelve examples. A small, dull, convex, narrow species, not very closely allied to any 
other here recorded. A male and female were sent from the Tres Marias Islands; the 
former has longer and thinner antenne and legs than examples of the same sex from 
the mainland ; the female is, however, identical. 
B. Anterior femora unarmed in both sexes. 
* Upper spur of the anterior tibie in the female longer and stouter than the 
lower spur. 
34, Elzodes longicornis. (Tab. IV. fig. 17,2.) 
Oblong ovate, convex, smooth, dull black. Head sparingly and very finely punctured; prothorax about as 
broad as long, a little more transverse in the female, convex, moderately rounded at the sides, about 
equally narrowed at base and apex, widest in the middle, anterior angles obtuse and a little prominent, 
hind angles obtuse, smooth and almost impunctate; elytra scarcely wider than the thorax at the base in 
the male, wider in the female, slightly elongate in the male, shorter and broader and the apex broadly 
rounded and scarcely attenuate in the female, widest a little behind the middle, the sides moderately 
rounded and feebly sinuate a little before the base in both sexes, the humeri distinct and, in the female, 
almost meeting the hind angles of the thorax, smooth and almost impunctate ; upper spur of anterior tibize 
in the female much longer and stouter than the lower spur; anterior femora unarmed in both sexes ; basal 
joints of the anterior tarsi in the male thickly clothed with hair beneath; antenne in the male rather 
long, the last three joints broad and stout, in the female shorter and stouter and the apical joints a little 
smaller than in the male. 
Length 12-13 millim. (3 9.) 
Hab. Mexico, Ciudad in Durango 8100 feet, Milpas 5900 feet (Forrer). 
Seven examples. A small, smooth, dull species, of a somewhat different facies from 
its allies.
