TREZON.—BOTHROBATYS. 607 
terminal claw long and arising from the outer apical angle; tarsi with joint 3 very broad and bilobed, 
the claws divergent, simple ; body elongate, depressed, densely squamose above. 
This genus includes a single species from Guatemala, somewhat resembling 
Mitrastethus baridioides, Redt., from New Zealand, and an undescribed form from 
Santa Catherina, Brazil *. 
1. Trezon encaustus, sp.n. (Tab. XXIX. figg. 29, 29 a.) 
Piceous, the antennsw obscure ferruginous; densely clothed with pale greyish-brown agglutinated scales, and 
also set with scattered, intermixed, suberect, pallid and black setiform scales, the latter condensed into a 
short, T-shaped mark at the apex of the elytra, the setiform scales on the legs pale brown; the abdomen 
shining and very sparsely squamose. Head densely punctate, slightly depressed down the middle in 
front; rostrum shining, very sparsely, finely punctate, the punctuation becoming closer at the tip; 
joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed and 
feebly constricted in front, and also a little narrowed behind, the hind angles obtuse, the base feebly 
bisinuate ; densely, finely punctate. Elytra seriate-punctate, the interstices flat and densely punctulate. 
Ventral segments sparsely punctate. 
Length 6, breadth 24 millim. (2?) 
Hab. Guatemaa, Torola, Pacific slope (Champion). 
One specimen.

A genus including a few Tropical-American species, recognizable by the sinuato- 
explanate sides of the prothorax. It is doubtful whether Lophocephala, Blanch., is 
really congeneric with Bothrobatys. |

Central-American specimens of this species (the type of which I have examined) 
usually have a very large common dorsal patch on the elytra, and the disc of the 
prothorax more or less, ochreous or fulvous, this colour in the type being almost 
confined to the sete clothing the dorsal prominences. ‘The prothorax is broad, and 
obtusely bidentate on each side. The vestiture is very dense, as in Collabismus. 
The length varies from 4;'5-63 millim. The Colombian examples in the British 
Museum have the prothorax still more dilated at the sides. 
* This insect is represented by a single specimen in the Pascoe collection ; it differs from 7. encaustus in 
having a shorter and broader prothorax, &c.
