3. Tilargus granulatus, sp. 1. 
Breviter ovalis, sat convexus, testaceus; pectore, abdomine, prothoracis disco elytrorumque maculis magnis 
fuscescentibus ; fere opacus, prothorace granulato-punctato. 
Long. 23, lat. 13 millim.

Though this insect bears a general resemblance to TZ’. dedilis, it is readily distin- 
guished therefrom by the peculiar, almost granulated sculpture of the pronotum, the 
surface of which is very dull; the pubescence is very fine and dense. The elytra are 
more distinctly punctured than usual, and the pubescence does not appear to be 
seriate ; the dark marks are but little pigmented, there being two on the suture, a 
large one on the disc of each, and one or two others even more indefinite. One 
specimen. 
4. Tilargus complicatus, sp.n. (Tab. XIX. fic. 11.) 
Ovalis, convexus, niger, pube flavescente vestitus ; antennis, palpis, pedibus elytrisque testaceis, his maculis 
irregularibus nigris ; corpore subtus anterius ferrugineo. 
Long. 23 millim. 
Hab. Guatemaa, Zapote (Champion) ; Panama, Bugaba (Champion). 
This is a remarkable species, with a very definite complex set of black marks on the 
elytra, forming extremely irregular fascia—a pattern that is not easy to describe, but 
will be readily recognized from the figure. The antenne are yellow, with stout club. 
Thorax very short, greatly narrowed in front, blackish, yellow towards the lateral 
margin; sculpture extremely fine and indistinct, but the pale pubescence very evident ; 
the basal notch on each side of the scutellum very distinct. Elytra very indistinctly 
punctate, but with a distinct pubescence which has some appearance of seriate 
arrangement arising from depressed sete. Two specimens. 
This species has the thick palpi of Tidargus, but in general appearance is more like 
a Litargus. It will probably form a distinct genus, but the two specimens are very 
fragile and scarcely fit for description. 
CATOPIUS, gen. nov. 
Tibie omnes ad apicem calcaribus elongatis et setis rigidis armate. 
With a general resemblance to Litargus that makes the relation of the two certain, 
this genus is nevertheless distinguished by other characters than those drawn from the 
remarkable structure of the tibial spurs. The antenne are slender, with a long slender 
club. The eyes are prominent. The prosternum is elongate, with a free acuminate 
process. ‘he front cox are larger than in Litargus, and the first ventral segment 
behind the coxa is not much longer than the second. The basal joint on all the
