STILODES. 223 



commencing below the humeral callus, and all the striae meeting irregularly near the apex. Underside 

 and legs black, shining, the last abdominal segments margined obscurely with fulvous ; metasternal 

 epipleurse coarsely punctured ; claws without teeth. 



Hab. Guatemala, Zapote, Paso Antonio (Champion). 



From 8. flavieans this species is easily distinguished by the regularly punctate-striate 

 elytra and the close punctuation of the thorax. S. ccelebs may be separated by the 

 smaller size, lighter colour, and different punctuation of its elytra. 



4. Stilodes caelebs. (Tab. xn. fig. 25.)

This seems to be a species of variable colour and punctuation ; and it is impossible to 

 say whether all the specimens contained in M. Salle's collection and those obtained 

 by Champion really represent one species only or not. Stal himself has described 

 several varieties in which the underside varies from testaceous to black. The punctua- 

 tion of the thorax seems, however, equally variable, as I have specimens distantly as 

 well as closely punctured before me, and intermediate degrees equally numerous. The 

 prevailing upper and under colour is a light yellowish brown ; the punctured striae on 

 the elytra are still more regular than those of S. modesta, and the two outer ones 

 are closer than the rest. In other specimens the tarsi and knees are black as well as 

 the scutellum. The insect is of a more elongate and parallel shape than S. modesta, 

 in which the two outer striae on the elytra are equally distant with the rest, and the 

 upper surface of a dark fulvous colour. 



5. Stilodes nigromarginata. (Tab. XIII. fig. l.) 



Ovate, convex, black below ; above obscure testaceous ; thorax closely punctured, margined with black ; 

 scutellum black ; elytra punctate-striate, the striae irregular, the suture narrowly black. 



Var. Underside and part of the tibiae obscure piceous (immature ?). 



Length 3^-4 lines. 



Head with a few fine punctures, testaceous, as well as the jaws, the apex of the latter piceous ; antennae black, 

 the two or three basal joints testaceous, the terminal joints gradually thickened, slightly longer than 

 broad, and extending beyond the base of the thorax. Thorax transverse, as broad as the base of the 

 elytra, the anterior and posterior margins slightly produced in the middle ; lateral margin rather regularly 

 rounded, the anterior angles distinctly produced but not very pointed ; surface closely covered with strong 

 punctures, less crowded on the disk than on the sides, and a row of deeper punctures situated at each side 

 of the posterior margin ; the latter as well as the anterior one very narrowly black. Scutellum of the 

 same colour. Elytra convex, testaceous, the disk more or less stained with obscure piceous, each elytron 

 with ten rows of very distinct punctures, the first one very short, the others often waved and irregular* 

 and disturbed by extra punctures ; of these rows the second and third and the fourth and fifth unite 

 at the base ; the punctures near the apex are finer, and ends of the striae all meet at that place. Elytral 

 epipleurse testaceous. Underside and legs black; claw- joint unarmed; metasternal epipleurae rugose- 

 punctate. 



Hab. Mexico, Jalapa (Hoge).
