Tue genus Sahlbergella, Hagl. (Fam. Capside) is now known 
by two species, both of which are injurious to the Cocoa-tree 
(Theobroma, sp.) 
Genus SAHLBERGELLA.

In 8. Ashanti, according to Dr. Graham (supra), ‘‘ very large 
numbers of these insects were found on the diseased trees, and 
not on the healthy ones. They appear to damage the trees by 
perforating the bark and so producing ‘ gumming.’”’ 
Sahlbergella theobroma, sp. n. 
Black; posterior lateral margins to pronotum, base and costal 
margin to corium, irregular segmental spots to connexivum, lateral 
areas of meso- and metasterna and disk of abdomen beneath fuscous 
or brownish-ochraceous ; antenne incrassate, basal joint considerably 
thickened and shorter than fourth joint, second gradually thickened 
from base, globosely incrassate at apex and about as long as head 
and pronotum together, second and third joints very stout and pyri- 
form, third longer than fourth; pronotum slightly but distinctly 
gibbous behind the anterior pronotal angles, rugose, with scattered 
tubercles ; scutellum prominently raised, rugose and tuberculate, the 
apex robustly posteriorly produced and slightly curved downward ; 
membrane opaque, considerably passing the abdominal apex; tibize 
robust and strongly shortly pilose, the tarsi stramineous. Long 
incl. tegm. 84 to 10 millim. 
Hab. Gold Coast: Fancheneko (Dudgeon—type Brit. Mus.) 
Allied to S. singularis, Hagl., but differing in the black 
coloration, the shorter second joint of the antenne, rugose 
pronotum and scutellum, and the more apically recurved 
scutellum.
