178 THE: ENTOMOLOGIST S RECORD. 
bicolor as the presence of the blunt projections on the mesonotum is, 
as far as | am aware, unique in this genus. ‘The end of the process is 
obliquely cut off, and has no resemblance to the spines in e.q., the genus 
Polyrhachis. The ant, according to the specimens I received, is some- 
what smaller than bicolor, i.sp., which, in specimens I took in Egypt, 
-attains a length of 12-Omm. 
Evans captured a few examples of this variety, two of which were 
sent to me, with the note that both specimens were found coming out 
of the same hole in the sand. ‘The 8 major is typical, but the ¢ 
minor is entirely orange yellow, with the gaster paler, and is altogether 
a stouter insect than the % % minor taken with Buxton’s examples.

Caniponotus (Myrmoturba) maculatus, F., subsp. evansi, subsp. noy. 
8 major (? media). L. 8:5-9°Omm. Width of head 2°3mm. 
Castaneous; scale darkest, head slightly darker than thorax, legs palest; 
gaster shining black, borders of segments rimmed with castaneous yellow. 
Whole insect robust, legs short. Head slightly broader than long, widest just 
behind the eyes, narrowing abruptly in front of eyes, which are well helind the 
middle of sides of head. . Occipital border widely and shallowly emarginate. 
Mandibles 7 toothed. Clypeus carinate on its posterior two-thirds only. anterior 
border straight. Scapes extend just beyond occipital border. Hyes large. flat. 
Thorax in profile short, regularly arched as far as the meso-epinotal suture whence 
the base of epinotum slopes down in a more or less straight line to meet the 
declivity, making a very abtuse angle with the latter, which is quite straight and 
somewhat shorter than the base. Tibiz somewhat flattened. Scale narrow at 
apex, convex anteriorly and straight behind. Gaster ova!, hardly larger than the 
head. 
Mandibles shining, with coarse punctures. Head dull, with a reticulate ground 
sculpture pitted with irregular somewhat elongate punctures, most abundant on the 
clypeus, cheeks, and between the frontal carine. Vertex and occiput with only 
scattered shallow punctures. Thorax with a finer reticulate ground sculpture, and 
more shining than the head; scale, legs and scapes with a similar reticulate 
sculpture. Gaster shining, with a superficial transverse reticulation. Declivity of 
epinotum shining, microscopically transversely reticulate. 
Head, thorax and gaster with rather long scattered yellowish hairs, whitish on 
gaster ; no pilosity on scapes or legs. Pubescence nil. 
% minor. 
Differs only in size, slightly smaller head proportionately, and greater length 
of scape. =
