TROCHODERUS.—STILICUS. 581 
1. Trochoderus godmani, (Tab. XV. fig. 5.) 
Niger, opacus, antennis pedibusque fusco-rufis, dense obsoleteque punctatus; elytris punctis majoribus sub- 
seriatis impressis. 
Long. 7-8 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
Antenne moderately stout; third joint a little longer than the second, the penultimate 
a little shorter than broad. Head subcircular, excessively densely and finely punctate, 
dull. Thorax longer than broad, a little narrowed behind, much narrowed in front, 
with a fine polished line along the middle quite vanishing in front. Elytra slightly 
longer than the thorax, densely and finely punctate, not quite so dull as the anterior 
parts; with some larger punctures along the suture and middle of each, and some 
still finer ones towards the sides. The male has a just perceptible emargination of the 
hind margin of the last ventral plate. 
A good series was obtained. Sandy banks of streams (Champion). 
2. Trochoderus dubius. 
Fuscus, pedibus antennisque versus apicem sordide rufis; dense subobsoleteque punctatus, elytris punctis 
parum conspicuis impressis. 
Long. 7 millim. 
Hab. GuateMAa, San Joaquin in Vera Paz (Champion). 
So far as I can judge from a single immature example, this is a rather smaller and 
less elongate insect than 7. godmani, with the punctuation not quite so dense and 
obsolete, and the front part of the thorax less elongate; the more pallid colour may be 
partly due to immaturity. Although so similar in appearance to 7. godmani, 1 think 
the structure of the labrum will be found to be different and less complex, as the median 
teeth do not appear to be duplicate. 
| STILICUS. 
Stilicus, Latreille, Régn. Anim. iv. p. 486; Er. Gen. et Spec. Staph. p. 629. 
This genus is widely distributed in both the Old and the New Worlds; but, as yet, 
only about thirty-five species have been described. In some of the species of our region 
the tarsi are bilobed, but the lobes are so slender that they are not easily perceived in 
dried examples, and I have therefore not used the character for dividing the genus 
into sections. | 
1. Stilicus angularis. (Tab. XV. fig. 6.) 
Stilicus angularis, Er. Gen. et Spec. Staph. p. 634°.

Cordova (Sallé). 
Of this distinct species we figure an individual from the Saunders collection.
