578 MONOTOMID&. 
median impunctate space on the thorax more definite, the punctures of the striz of the 
elytra very minute, the pygidium of the male rather stouter, and the fovea of the last 
ventral segment obscure. One pair. 
Subfam. T7STPHONINAE. 
The position of this subfamily is doubtful, a very careful analysis being requisite 
before we can decide whether the single genus referred to it, Z¢szphone, Reitter, should 
be placed in Monotomide, Nitidulide, or Cucujide. It consists at present of a few rare 
and minute insects found in the Southern States of North America, the Antilles, and 
Northern South America. I have at present before me eight species, viz.: the three 
here described from Mexico and Central America; the two species upon which the 
genus Tisiphone was founded, viz. 7. hypocoproides and T. nitiduloides, from the 
Antilles; TJ. eaxilis, Grouvelle (Murray %), from Grenada; a species from Jamaica 
allied to 7. nitiduloides, in my own collection; and the N.-American 7. palmicola, Lec.

1. Tisiphone chontalenus, sp.n. (Tab. XVIII. fig. 7.) 
Depressus, opacus, rufus, elytris obscurioribus, vage fusco-limbatis; antennis pedibusque testaceis; supra 
subtilissime, ubique sequaliter punctatus. 
Long. 13 millim. 
Hab. Nicaraeva, Chontales (Janson). 
Var.? Pygidio valde elongato. 
Hab. Guatemaa, San Juan in Vera Paz (Champion). 
Antenne rather slender. Head somewhat small; eyes large, separated by but a 
little distance from the points of insertion of the antenne. Thorax transverse, slightly 
rounded at the sides; hind angles nearly rectangular; surface densely and finely 
punctured, without smooth space along the middle. LElytra and pygidium punctured 
like the thorax ; the pygidium elongate. 
This species is distinguished from the North-American Smicrips palmicola by its 
more elongate and depressed form, by the larger but less convex eyes, from which the 
antenne are less remote, and by the horizontal and much longer pygidium. ‘The three 
examples from Chontales agree, except in a slight difference in colour. The single 
specimen from Guatemala, in addition to its very elongate pygidium, has the punctua- 
tion of the thorax slightly stronger.
