Melissodes luteicornis falls in a new subgenus, which I 
propose to call Martinella, after my little son. Besides the 
characters of the palpi, it is distinguished by its yellow 
antennz in the male, and strongly banded abdomen. I am 
myself confident that it was derived from some Synhalonia- 
like form quite independently of the rest of the genus 
Melissodes ; if this can be proved, Martinella will, of course, 
rank as a genus. 
DASIAPIS, gen. nov. 
Belongs to the Anthophorini. Similar to Diadasta, but 
clypeus and labrum in male white; middle and hind tibize of 
male incrassate ; tarsi of male normal, except that first joint 
of hind tarsi is somewhat curved; maxillary palpi with six 
long cylindrical joints, the third and fourth without the lateral 
brushes of hair seen in Diadasia *. 
Dasiapis ochracea, sp. n. 
6 .—Length about 10 millim. 
Covered all over (except the smooth shining vertex) with 
light ochraceous pubescence ; facial quadrangle much longer 
than broad, narrowed below ; face densely covered with hair; 
clypeus, labrum, and basal part of mandibles white; man- 
dibles simple; antenne very short (as in Diadasia), flagellum 
ferruginous beneath; scape slender, black; mesothorax dull ; 
tecule large, ferruginous. Wings faintly dusky; stigma 
rather large, ferruginous ; nervures fuscous ; venation as in 
Diadasia ; second submarginal cell narrowed above; third 
rounded (not truncate) at end; basal nervure meeting trans- 
verso-medial. Legs with long coarse hair ; tarsi ferruginous ; 
abdomen rather long and narrow, shining but covered with 
appressed ochraceous hair; first segment with no transverse 
keel ; venter shining, with apical hair-bands on the segments.

but these are no doubt morphologically the third and fourth, the long 
first joint representing two united,
