and Central American Telephorinae. 67 



slender, subfiliform, closely pilose. Prothorax strongly trans- 

 verse, with a narrow, deeply-cut, oblique notch on each side just 

 before the base, the hind angles obtuse. Elytra long, at the base 

 of the same width as the prothorax, broadly arcuato-explanate 

 from a little below the shoulder. Sixth ventral segment deeply, 

 triangularly emarginate; seventh segment long, the two lobes 

 scarcely raised posteriorly, the median fissure somewhat open, 

 leaving a portion of the eighth segment exposed. Inner claw of 

 anterior tarsi and outer claw of middle tarsi broadly lobed ; outer 

 claw of posterior tarsi deeply cleft, the outer portion of the claw 

 much shorter than the inner. 



Var. $. Prothorax wholly testaceous, broadly explanate at the 

 sides, arcuately narrowing forwards, the margins feebly sinuate.

 Telephorus photurinus, Gorh., loc. cit. pi. 6, fig. 19 ($). 



(^. Eighth ventral segment simply cleft at the apex; ninth 

 segment produced on each side into a long, dentiform process, two 

 broader, compressed, abruptly-pointed hooks projecting from the 

 internal sac and two spines visible between them (fig. 24, profile 

 view).

Redescribed from Gorham's types — two males. The 

 females he subsequently referred to D. perplexum are 

 colour-varieties of his D. luridum, but his D. difficile, $, 

 from Yolos, which has slender antennae, almost certainly 

 belongs here. Differs from D. normale in the broadly 

 explanate, posteriorly attenuate elytra ; the longer, 

 slender, subfiliform antennae ; the more oblique, juxta- 

 basal incisure of the prothorax; and in the genital 

 armature.

Broad, black or piceous, the sides of the head in front, the base 

 of the mandibles, the prothorax (a broad median vitta or triangular 

 patch excepted), and the apex and sides of the abdomen flavous, 

 the elytra uniformly brownish-ochraceous. Antennae {^) moderately 

 long, rather stout, subserrate, tapering outwards, closely pilose; 

 ($) shorter, sparsely pilose. Prothorax with a narrow, deep.
