specimen, and seems scarcely to vary from most of the others belonging- to his 

 fourth section. 



11. Pachybrachys incrassatus.

Hob. Mexico, Jalapa 1 ; Guatemala, San Geronimo {Champion). 



The shorter antenna (which do not extend to half the length of the body) the 

 close and strong punctuation of the thorax, and the irregularly sinuate cost* of the 

 elytra form the principal distinguishing characters of this species, to which I reier a 

 male (a sex unknown to SufFrian) sent by Mr. Champion, and which agrees well enough 

 with the type in the Berlin Museum. The general colour is yellow, with brown lines 

 and punctures. 



12. Pachybrachys longulus. 



Pachybrachys longulus, Suffr. Monogr. vii. p. 207. 



Hah. Mexico. 



Again a closely allied species to the preceding ones, but separated by the long and 

 narrow cylindrical body and the white colour at the sides of the abdominal segments. 

 The type in the Berlin Museum is a female, the antennae of which reach nearly to the 

 end of the body. The elytra are very closely and irregularly covered with brown punc- 

 tures ; and the legs and underside are of the same colour. 



13. Pachybrachys punctatissimus. (Tab. IV. fig. 20.) 



Broad parallel, brown below ; head and tborax closely punctured, the latter with two longitudinal bands and 

 the margins yeUow ; elytra light yellow, covered closely with brown punctures. 



HTadlltlngly closely rugose punctate, brown, with irregular spots of yellow ; antennae extending to one 

 third the length of the body, the apical joints rather robust and much widened, black, basal joint fulvous ; 

 thorax of equal width, its sides straight, posterior margin distinctly produced at the middle ; surface very 

 closely evenly, and deeply punctate, brown, interrupted here and there by small yellow spots, and divided 

 longitudinally by two bands of the same colour, more or less distinct ; scutellum dark brown ; elytra punc- 

 tured like the thorax, the punctures themselves brown, the interstices light yellow, and now and then 

 arranged into smooth, narrow, longitudinal costa? ; underside and legs darker or lighter brown ; female 

 with some brown spots near the apex of the elytra. 



Eab. Mexico, La Parada, Cuernavaca (Salle). 



A species allied to P. longulus, Suifr., from which it is distinguished by its shorter 

 body, antennae, and the very close and rugose punctuation of the head; that of 

 the elytra in P. longulus is also finer, and does not extend quite to the apex; and 

 the abdomen in the present species is without the white spots. A specimen in the 

 collection of Mr. Baly slightly exceeds two lines, and is proportionally robust.
