278 NITIDULIDA. 
1. Brachypeplus vicinus, sp. n. (Tab. VIII. fig. 20, ¢ .) 
Depressus, dense subtiliter punctatus, subtiliter pubescens, opacus, fuscus, prothoracis lateribus, antennis 
pedibusque testaceis, antennarum clava nigro-fusca; prothorace transverso; elytris subtiliter costatis. 
Long. 43-5 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Var. Minor, long. 33 millim.; pallidior, vix adeo dense punctatus. 
Hab. Panama, Bugaba (Champion). 
Head densely and finely punctate, feebly pubescent, very indistinctly bi-impressed in 
front. Thorax rather strongly transverse, only slightly curved at the sides, a little 
emarginate in front, the hind angles a little produced backwards, and slightly acute, 
the surface densely, moderately finely, subrugosely punctate. Elytra not quite so long 
as their united width, very delicately costate, with the interstices closely and finely 
punctured, the hind angles very much rounded. Hind body very densely and finely 
punctured. Male with a large supplementary segment, the last ventral plate somewhat 
impressed or deplanate along the middle, and more densely punctate. 
Allied to B. anceps, Murray. The variety from Bugaba is represented by only one 
female, and may be distinct. There are, I believe, two or three closely allied species 
extant in collections as B. anceps, Murray; but the present one does not agree with 
any other I have seen, though it comes nearest to an insect from Bahia, which has a 
rather shorter thorax, with less prominent front angles. 
2. Brachypeplus costatus, sp.n. (Tab. VIII. fig. 22.) 
Valde depressus, parallelus, parce minus subtiliter pubescens, opacus, fuscus; prothorace valde transverso, 
dense fortiter punctato; elytris argute costatis. 
Long. 43-54 millim. 
Hab. Guatemata, Cerro Zunil (Champion). 
Head closely and coarsely, but not deeply, punctate. Thorax very strongly trans- 
verse, quite truncate in front, the anterior angles entirely rounded, the sides nearly 
straight, a little narrowed behind, the hind angles obtuse, the surface coarsely punctate, 
covered with depressed sete. Scutellum triangular, coarsely punctate. LElytra nearly 
twice as long as the thorax; with very regular distinct coste, and the grooves between 
them very obsoletely punctuate. Hind body coarsely punctate, the lateral margins 
strongly curved. 
We have received only two specimens of this distinct species; both apparently are 
females. 
3. Brachypeplus brachypterus, sp. n. 
Perdepressus, parallelus, dense subtiliter punctulatus, subtiliter pubescens, fusco-ferrugineus; prothorace 
transverso ; elytris obsolete costatis. 
Long. 34 millim. ,
