XYLOCOPA RUFITARSIS, Lepeletier. 
9. Impendhle, January, 1916 (E.C. Chubb). The mandibles have 
a tubercle on the upper-side toward the base, and the fourth abdominal 
segment has a black opaque mark on each side basally. ‘The wings 
are somewhat more pointed than in X. carinata, and the punctures of 
the mesothorax are smaller. The flagellum is black. 
MEsorTrRicHiA BEVISI, Cockerell. 
The type has only two sub-marginal cells, but two males now before 
me, collected by Mr. Bevis, at Umbilo, have three sub-marginals. 
Evidently the insect varies in this respect, but the other characters 
amply distinguish it. 
Crocisa CALCEATA, Vachal. 
2. Bellair, Natal, 13th January, 1919 (KE. C. Chubb). 
CROCISA CYANESCENS, Sp. nov. 
2? (type). Length about 12 mm.; markings very pale blue ; 
scutellum deeply incised, but sides of incision flexuose ; long white 
hair projecting from beneath incision ; disc of secutellum with black 
hair, but no light spots ; axilla with spots of light hair ; hind femora 
not toothed ; hair-markings on each side of first abdominal segment 
U-like; bands on each side of second segment thick, a little longer 
than the interval between them, and with no lateral anterior lobe ; 
hind tibiz with less than basal half white-haired ; hind basitarsi 
white-haired posteriorly ; ventral surface of thorax with white hair. 
General appearance and markings as in C. calceata, but larger, with 
the marginal cell distinctly longer, scutellum more deeply incised. 
3. Length about 12 mm.; axillar spots very small ; rather more 
than basal half of hind tibiz light-haired ; end of abdomen with two 
prominent, widely separated teeth, much better developed than those 
of C. calceata. Scutellum and mesothorax shining. 
Type from Malvern, Natal, 16th January (Barker). Male from 
Umbilo, 22nd March, 1913 (A. L. Bevis). 
This looks just lke the Indian C. ramakrishne, Ckll., the only 
obvious superficial difference being that the wings are not so dark.
