174 RHYNCHOPHORA. 
4. Sciomias latipennis, sp. n. (Tab. VII. fig. 12.) 
Brunneus, ochraceo fuscoque squamosus; antennis pedibusque rufis; elytris setis minutis subtilis vestitis, sat 
fortiter seriatim punctatis, interstitiis parum convexis. 
Long. 33 millim. 
Hab. Guatemata, San Gerdénimo (Champion). 
This species is remarkable by the form of the elytra, which are broad and convex, 
but nevertheless with the dorsum somewhat flattened. Antenne rather short, yellow, 
unicolorous, second joint of funiculus small. Head and rostrum covered with scales 
as far forward as the deep scrobes. Thorax small, subcylindric, deeply punctured, but 
the sculpture concealed by scales, with a slight shining carina-like space on the middle. 
Elytra at base just as broad as the base of the thorax, but becoming very rapidly 
wider, so that the shoulders are perfectly rounded; covered with scales, which are 
slightly variegate, and bearing erect, short, truncate sete. ‘Two specimens. 
PARASOMUS, gen. nov. 
Femora dentata. Unguiculi vix connati. 
The insect for which I establish this genus much resembles the European Sciaphilt 
and Eusomi, except that it is of rather shorter form ; it is distinguished from them, as 
well as from the other genera of Sciaphilina found in our region, by the fact that the 
claws at their bases are very narrowly separated; possibly they may prove to be 
connate at their articulation within the claw-joint. Independently of this, the genus 
may be identified by the dentate femora. If the claws prove to be really free, I think 
the insect would be better placed in the Epicerina near Clezstolophus and the other 
genera of that group with dentate femora. 
The antenne are moderately stout, the scape about attaining the front margin of 
the thorax. ‘The rostrum is moderately long, slightly broader at the tip, which is 
provided with a small, deeply-impressed nasal plate; the eyes encroach on the front 
and are oval, only slightly prominent; the scrobes are short, slightly descending, 
broader behind, not nearly reaching the eye. The mentum is not broad, but fills the 
buccal cavity, neither the maxille nor the palpi being exposed. The prosternum is 
short, the coxe are contiguous and placed very near the front of the thorax. ‘The 
metasternum is short; the first ventral segment is much longer than the second. ‘The 
anterior tibiee are armed with a long slender claw at the inner apical angle. The tips 
of the hind tibiz are simple; the corbels not in any degree cavernous. The under 
surface is squamose.
