distinct large rounded apical lobe, not developed in the Madeira 
form. Type in British Museum; the cotype will be placed in 
U.S. Nat. Museum. 
“ S. abbreviatus desertarum subsp. n. This is Wollaston’s 
var. 5 from the Desertas. It is larger and looks like cimensis, 
‘but the mandibles differ, and, as Mr. Blair pointed out, the 
margin of the thorax is broadly interrupted posteriorly. In 
cimensis the margin is suddenly deflected or bent at a point 
behind the middle of the prothorax, apparently indicating 
that the structure is produced by two separate factors in 
inheritance, one of which has dropped out in desertarum. 
Type in Wollaston collection, Brit. Museum. 
Small Forms. 
“ 8. abbreviatus partosanctanus subsp. n. This is Wollaston’s 
var. 8, but I take as the type one of my specimens from Itheo 
de Baixo, Jan. 22,1921. It is the smallest of the races, 19-20 
mm. long, but resembles the Cima one, and not that of Madeira, 
in the sculpture of the base of the elytra. As Wollaston 
remarks, the elytra are also more broadened posteriorly. The 
mesal lobe of the left mandible lacks the apical lobe or ex- 
pansion, but differs from that of the Madeira form in being 
more obtuse, with its upper face obliquely striate. Type in 
British Museum; cotype kept for U.S. Nat. Museum. 
“8. abbreviatus, typical form from Madeira. Wollaston 
also distinguishes a variety from the Itheo de Fora, at the end 
of Madeira, opposite the Desertas. 
“JT exhibit a few other insects, interesting for various 
reasons :— 
“ Bombus ruderatus (Fabricius). Fabricius described his 
Apis ruderata partly from material collected in Madeira by 
Sir Joseph Banks, on Captain Cook’s first expedition. It was 
interesting to find the same species in abundance in a meadow 
at Funchal, March 2, 1921. It was visiting flowers of Echiwm. 
“ Rhyparobia maderae (Fabricius), also described in the 
early days from Madeira, but now cosmopolitan. It probably 
did not originate in Madeira. The specimen is from Funchal. 
“ Ohrysomela banksi Fabricius, collected by Mr. A. C. de 
Noronha on the right bank of the Ribeira de Porto Novo,
