The postnotum (figs. 3 A, 4 F, pn) is the short transverse scleriteextending across the dorsum from one pleuron to the other and sepa-rated from the scutum and the scutellum by the postnotal suture(pns). It is connected by a very short membrane to the first ab-dominal tergite, and at the sides is reflected around the first abdominal 26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 94 .prp, VPr ^.?^^-^^ irla.

Along the posterior part of the sclerite extends asuture from the postnotal articulation to the midline, marking thelocation of an interior ridge. This is the antecostal suture (acs).There is no vestiture on the postnotum, but the narrow area caudadof the antecostal suture is finely muricate. The central area is denselycovered with extremely minute rounded papilliform processes orexcrescences. The axillary sclerites will be describe
