TEICHOSTETHUS.—STRONGYLUS. 355 
but very shallow, punctures; each interstice with a series of finer punctures along 
the middle. 
The four examples we have received of this species are not in very good condition ; 
the coloration of the upper surface is not very sharply defined and is probably variable. 
2. Teichostethus guatemalenus, sp.n. (Tab. XI. fig. 13.) 
Ovalis, convexus, rufo-ferrugineus, antennarum clava nigra; hispidus pube erecta; prothorace crebre fortiter 
punctato. 
Long. 33 millim. 
Hab. GuateMata, San Isidro, Zapote, San Gerdénimo (Champion). 
This insect is very closely allied to 7, vinosus, but I have little doubt is distinct ; it is 
rather smaller and narrower, and without black markings; the antenne are less elongate ; 
and the punctuation and setosity of the upper surface are closer. The peculiar punc- 
tures of the thorax, owing to being more closely placed, are seen to have a curved 
arrangement in front of the scutellum. 
STRONGYLUS. 
Strongylus, Herbst, Natursyst. Kifer, iv. p. 188 (1793). 
Cyllodes, Erichson, in Germar’s Zeitschr. iv. p. 342. 
Strongylus at present contains about twelve species; but it is very widely distributed 
in both hemispheres, and will probably become an extensive genus. Species belonging 
to it are already known from both North and South America. 
1. Strongylus unicolor, sp. n. (Tab. XI. fig. 14.) 
Rotundato-ovalis, convexus, nitidus, nigerrimus, antennarum basi tarsisque rufis. 
Long. 43 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (. H. Smith), Juquila (Sallé). 
Antenne with elongate club, the first joint of which is rather longer than broad, 
the terminal joint ferruginous at the extremity. Head closely and moderately coarsely 
punctured. Thorax with the punctuation very distinct, but finer and less close than 
that on the head. Scutellum almost impunctate. LElytra with fine and irregular, 
almost duplicate, series of punctures, and with a very fine and scanty interstitial 
punctuation. 
2. Strongylus lateralis, sp. n. (Tab. XI. figg. 15, 16.) 
Ovalis, convexus, nigerrimus, nitidus, antennarum basi, prothoracis lateribus tarsisque rufis. 
Long. 47 millim. 
Hab. Guatemata, Cerro Zunil, Capetillo (Champion). 
This msect is rather smaller than S. wnicolor, and has the sides of the thorax very
