Tetrapedia lacteipennis Vachal.—It should be added to Vachal's description, that the dorsal abdominal segments 2 to 4 have yellow bands.
The Bartica collection contains a Megalopta from Hoorie, but it is unfortunately broken. I have Megalopta panamensis Cockerell from Maroni, French Guiana (Queensland Museum, 42).
I add the description of a new species from French Guiana, the type of which is in my collection.
Augochlora maroniana, new species
♀.—Length slightly over 8 mm.; head, thorax and legs bright green; abdomen yellowish green strongly suffused with coppery, the first two segments with apical fringes of orange hair; face rather narrow; antennæ black; lower middle of clypeus black; mesothorax and scutellum rough with dense punctatures, the scutellum with two copper-red spots; area of metathorax with very feeble plicæ; tegulæ black with pallid margin, the basal side broadly green; wings dusky; second s. m. square; first r. n. meeting second t. c; stigma dusky reddish; legs with mainly pale hair, hind tibiæ with dark hair on outer side basally; hind spur with about six long spines; basal half of basitarsi green on outer side; abdomen shining, with pale ochreus hair.
Maroni, French Guiana (Queensland Mus., 43). Related to A. cupreola (Ckll.), but with the vibrissate fringes on abdomen nearly twice as long, and deep orange-fulvous, and the mesothorax much more densely punctured. Also related to A. diversipennis (Lep.), but with the face much narrower, and the area of metathorax much less distinctly plicate. From A. calypso Sm. it is known by the wings not being yellowish, the inner orbits not edged with blue, and the tarsi not ferruginous.
