little-known Species of Ants. 95 
It exists in all the specimens of the new species that [ have 
examined (viz. twenty-two), and can readily be seen under a 
fairly high power of the porro-prism binocular, but is much 
clearer when the funiculus is mounted in Canada balsam. 
Type in the British Museum. 
Camponotus (Myrmotrema) troglodytes, For., 
race assumptionis, st. nov. 
8% major. Length 7-0-8:°5 mm. 
Dark red ; gaster brown, the first segment often reddish ; 
borders of segments testaceous. 
Head broader than long, widest at upper border of eyes, 
narrowing rapidly in front of eyes, which are placed less than 
tlie length of an eye from the occipital border. Posterior 
half of clypeus raised, anterior half depressed, the anterior 
border widely and teebly emarginate, with serrate edge. 
Mandibles 5-toothed. Scapes extend about one-quarter of 
their length beyond the ozcipital border, which is feebly 
concave. 
Thorax: line of back unbroken, as in troglodytes. Declivity 
of epinotum longer than the base, with which it forms a 
rounded angle ; itis slightly concave at base and not bordered. 
‘The angle between the two faces greater than a right angle. 
Dull; gaster somewhat shining. Whole body with a 
fine reticulate ground-sculpture, finest on gaster. Mandibles 
with close clean-cut punctures, small ; clypeus with irregular 
larger ones. Rest of head with irregular shallow punctures, 
as in foraminosus, which tend to disappear at the occiput. 
Thorax has only a few faint punctures here and there. 
Pilosity : head and thorax bear a few stiff yellowish hairs ; 
declivity of epinotum edged with six to eight long, stiff, 
white bristles ; scale and borders of segments of gaster edged 
with similar white bristles, which on the gaster are often 
yellowish. In addition the body is scattered with fine golden 
adpressed hairs, which on the gaster are sufficiently numerous 
to give it a golden sheen. Legs and scapes without erect 
hairs. 
8% minor. Length 5°3 mm. 
Altogether paler, head narrower, scapes passing the occiput 
by nearly half their length ; fall of declivity of epinotum less 
abrupt. Otherwise like % major. .

I originally described this ant as a race of foraminosus, 
For., but Santschi considers it a race of troglodytes (which I
