HOLISUS. 465 
without impression on the front margin in the middle. Thorax rather elongate, as long 
as broad, the punctures on either side not very numerous, and not coarse. 
This species has the head rather longer than is usual, and the hind body more coarsely 
and densely punctate. Only two examples have been found. 
9. Holisus oblitus. (Tab. XII. fig. 10.) 
Angustulus, depressus, niger; elytris sordide testaceis, basi nigricante, pedibus fuscis; abdominis segmento 
ultimo posterius plus minusve anguste rufo ; capite thoraceque crebrius punctatis; elytris dense subtiliter, 
abdomine dense fortiter, punctatis. 
Long. 5-6 millim. 
Hab. GuaTEMALA, near the city, Cerro Zunil 4000 to 5000 feet, Purula (Cham- 
pion). 
Head quadrate, black, its punctures very numerous so that the medial smooth 
space is greatly reduced and obscure. ‘Thorax rather short, its punctures numerous. 
Elytra elongate, densely and not finely punctate, the punctures being rather deep and 
definite. Hind body black, the hind margins of the segments more or less distinctly 
ferruginous, the terminal segment more broadly so than the others. 
Eight examples have been found; of these four from Cerro Zunil and two from 
Guatemala city agree pretty closely ; the one from Capetillo has the hind body blacker, 
while, on the contrary, the example from Purula has the terminal segment entirely 
rufescent, and the hind margin of the one preceding rather broadly of that colour. 
The example figured is a male found at Cerro Zunil. 
10. Holisus elatus. (Tab. XII. fig. 11.) 
Latior, depressus, nitidus, rufus ; capite nigro, abdominis segmentis basalibus late fuscescentibus ; elytris sub- 
opacis, crebre subtiliter punctatis. 
Long. 7 miliim. 
Hab. Guatemata, San Gerénimo (Champion); Panama, Bugaba, Volcan de Chiriqui 
(Champion). 
Head quadrate, its punctures numerous and coarse; the triangular central space free 
from punctures is large, and the anterior punctures form three definite patches. Thorax 
greatly narrowed behind, its punctures moderately numerous. LElytra dull, of a more 
pallid red colour than the thorax. Hind body coarsely and closely, the apical segments 
more sparingly, punctate. 
The two examples found at San Gerénimo differ somewhat in the extent of develop- 
ment of the black colour of the hind body: the one figured is the darker of these. The 
examples from Bugaba are a good deal narrower than the type, and the two from the 
Volcan de Chiriqui are also slight varieties.
