BRENTHUS. 69 
Hab. Nicaragua, Chontales (Belt, Janson); Costa Rica (Sallé), Caché, Volean de 
Irazu (Rogers); Panama, Bugaba, Volcan de Chiriqui (Champion). 
Of this insect we have also received a good series of about thirty examples. I see 
nothing to distinguish it from B. guatemalenus, except the total absence of red colour 
from the surface; it appears to occur only in the more southern divisions of our region, 
while B. guatemalenus and B. variegatus are confined to Guatemala. I have selected 
geographical terms for the trivial names, as I cannot but think that these forms may 
be proved to be merely races of one species; indeed, I am extremely surprised at 
the absence of intermediate forms. 
11. Brenthus multilineatus, sp. n. 
Nigerrimus ; elytris flavo-lineatis, interstitio quarto linea elongata aliaque brevi, interstitio tertio lineis duabus 
mediocriter elongatis. 
Long. 11-22 millim. 
Hab. Guaremata, Cubilguitz in Vera Paz (Champion); Panama, Chiriqui (Ribbe).— 
Cotomsia, Bogota (coll. Sharp). 
We have received from each of the localities only one example of this species ; they 
are males, one of them of the smallest size. It differs from B. chiriquensis by the 
fact that the third and fourth interstices are each marked with two yellow lines, 
instead of one; the third has a rather short yellow line on the middle, and another 
somewhat longer line behind it; the fourth has a long line extending from the base to 
near the middle, and just behind the middle a short line forming a splice with the two 
lines on the third interstice. In addition to this distinction, B. multilineatus has the 
base of the thorax less rounded at the sides. | 
The male individual from Bogota agrees with the specimen from Guatemala, except 
that it is larger, being 29 millim. long. It is possible that this insect may be a variety 
of B. unidentatus, Kirsch; but that name is not available, there being a prior Bb. uni- 
dentatus described by Perroud. 
§ 2. Prothorax not sulcate along the middle. 
12. Brenthus clavipes, sp.n. (Lab. III. figg. 5, 3; 5 a, anterior leg.) 
Niger, nitidus; elytris linea elongata prope suturam lineaque valde abbreviata in margine laterali flavis, prope 
suturam quadristriatis, externe seriatim subtiliter punctatis ; femoribus crassis, basi abrupte pedunculata. 
Long. 11-15 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet, Tolé (Champion). 
Antenne short and thick. Head considerably narrowed behind. Thorax broad 
behind, a good deal narrowed towards the front, black and shining. Elytra short, 
each with four fine strie near the suture, and externally with series of very fine 
punctures; the third interstice is yellow on the apical portion, the fourth from the
