2. Stilicus cribratus, (Tab. XV. fig. 7.) 
Niger, antennis palpisque testaceis, pedibus pallide flavis, capite prothoraceque dense fortiterque rugoso-punc- 
tatis, hoc medio linea elevata levigata exarato; elytris fortiter profundeque punctatis, nitidis. 
Long. 44-54 millim. 
Hab. Mexico, Cordova (Sallé); Guatemata (Sallé), near the city, San Gerénimo, El 
Tumbador, Cahabon (Champion); Panama, David, Volcan de Chiriqui 3000 to 4000 feet 
(Champion). 
Head not very broad. Thorax rather slender, longer than broad, with the lateral 
angles very distinct, the portion in front of them elongate; the surface very 
convex transversely, and very densely and coarsely punctate, the smooth line down 
the middle very distinct. The elytra are longer than the thorax, and are remark- 
able on account of the coarse deep punctuation with shining interstices. The hind 
body is excessively finely punctate, shining, the three basal segments depressed at the 
base and more coarsely punctate in the depressions. The male has the hind margin of 
the last ventral segment feebly bisinuate, the median angle being very minute; the 
terminal segment has a rather small angular excision. 
We have received only two examples from Mexico, both females; they have the 
thorax a little broader than the specimens from Guatemala and the State of Panama. 
The species is no doubt closely allied to the Colombian S. carinatus, Er.; but it would 
_appear from Erichson’s description that the male characters are more largely developed 
in that insect. 
We have received a good series of this species; indeed it is apparently the only 
Stilicus at all common in our region. Our figure represents an individual from 
Guatemala city. | 
3. Stilicus guatemalenus. 
Niger, subseneus, antennis palpisque testaceis, pedibus pallide flavis, capite prothoraceque dense fortiterque rugoso- 
punctatis, hoc medio linea laevigata elevata exarato; elytris fortiter profundeque punctatis, nitidis, punctis 
versus apicem evidenter subtilioribus. 
Long. 6 millim. 
Hab. GUATEMALA, near the city, San Gerénimo, Las Mercedes, Volcan de Atitlan 
2500 feet (Champion). 
This insect is very closely allied to 8. eribratus, but is rather larger and has a broader 
head and thorax; the elytra are a little longer and their punctuation is not quite so 
coarse and deep, and on the apical fourth is evidently finer and more regular than 
elsewhere ; the male has a much longer tooth in the middle of the emargination of 
the penultimate ventral segment. 
This agrees with Erichson’s description of 8. carinatus even better than S. cribratus 
does ; but as S. guatemalenus has been found only in Guatemala, and is apparently rare
