first r. n. near the beginning of its last third; no black hair on head or thorax; 
the abundant hair of head, pleura and mesothorax entirely snow-white; that of 
metathorax, scutellum and abdomen more or less strongly stained with yellow- 
ish, that of the apical part of the abdomen quite ochreous; ocelli ruby-color; 
mesothorax shining and punctured; hind margins of abdominal segments broadly 
yellowish-hyaline, the hair-bands apical and only moderately conspicuous, the 
region between the bands being more or less hairy; the last three sef;ments with 
p)omine}it lateral teeth\ legs black with white hair, only the claw-joints rufous; 
hair on inner side of basal joints of middle and hind tarsi clear ferruginous. 
The abdomen is not quite so broad as that of .)/. semltnstis. 
Hah. Oak Creek Canyon, .Arizona, 6000 ft. {E. //. Snow, 2010). The 
peculiar appearance of the clypeus suggests that it may have failed to attain its 
natural color, but assuming this part to be naturally yellow; it is still impossible 
to identify the species with anything previously described. Seen from behind, 
the insect could very well be taken for M. menuacha, but in front the much darker 
antennae, narrower face, dark eyes and white pubescence are distinctive enough. 
M. Sairxr’ Cr., which has the white pubescence in front, has it also behind, 
besides being much smaller. 
Melissodes duplocincta, n. sp. 
A species with a narrow abdomen and bluish-white pubescence, having a 
remarkable superficial resemblance to Synhalonia lippiae (Ckll. ), but the sub- 
apical band on second abdominal segment, which in lippiae is reduced to a line 
on each side, is in duplocincta entire and even, so that the anterior part of the 
abdomen is girt by by two parallel clean-cut white bands, separated by a black 
interval about as wide as either of them. The third and fourth segments in the 
female, and the third to fifth in the mate, have broad even white bands. The 
pubescence of the head, thorax and legs is white, but the disc of the scutellum is 
covered with short black hair, and some greyish-brown hair is mi.xed with the 
white on the mesothorax, producing in the 9 a curious streaked or mottled 
appearance, as though the hair were stained; the hair of the vertex is entirely 
white in the S , but there are dusky hairs just behind the ocelli in the 9 . 
S Length about 10 mm.; antennae long, about y.j mm.; scape stout; flagel- 
lum slender, clear ferruginous beneath, except the apical two or three joints, 
which have not the form of Synhalonia-, clypeus lemon-yellow, with a large 
squarish black mark at each side above; labruin pale yellow; base of mandibles 
entirely yellow; tegulae light fulvous; wings clear, stigma ferruginous, nervures 
fuscous; second s. m. almost exactly square, receiving the first r. n. almost at its
