patches on sides of third to fifth segments, spots only on third; short bands 

 on the others. Maxillary palpi bristly, 6-jointed, the joints measuring as 

 follows in microns : (i) 208,(2) 176,(3) 192,(4) 112,(5) 96,(6) 112. Labial 

 palpi with joints measuring: (i) 1280, (2) 640, (3) 120, (4) 128. Paraglossae 

 long and slender. 



Habitat. — Guayaqtiil (v. Buchzvald; Alfken coll. 14). 



A very distinct species, superficially rather like T. acbra Friese. 

 The ornamentation of the abdomen recalls that of T. mclectoidcs 

 Smith, from Villa Nova on the Amazon, but that has hyaline wings 

 and various other distinctive characters. 



I will take this occasion to note that Tctralonia pygialis Buyss., 

 from Venezuela, evidently belongs to Thygatcr. 



Melisodes ecuadoria Bertoni & Schrottky. 



This species, found at Guayaquil, was named by Friese in manu- 

 script, and published with only a few words of description by Bertoni 

 and Schrottky in 1910. Only the female was known; but the male 

 before me, from Guayaquil, May-June, 1913 {Brucs), has the char- 

 acters to be expected in the species, and being from the same locality, 

 is presumably identical. The maxillary palpi agree sufficiently with 

 the description and figure of Bertoni and Schrottky. 



Male. — Black, abdomen with metallic tints ; clypeus lemon yellow, with a 

 black spot on each side ; labrum and large patch on base of mandibles cream- 

 color; eyes black; hair of head and thorax ferruginous, paler beneath, black 

 on posterior middle of mesothorax and on scutellum ; antennae very long, 

 flagellum clear ferruginous beneath ; tegulse ferruginous ; wings dusky ; nerv- 

 ures dark reddish ; second s. m. large ; upper apical side of marginal cell 

 angulate, though obtusely, not evenly rounded as in Florilegus pavoninus ; 

 tarsi, anterior tibiae in front, and the other tibiae at apex, ferruginous ; hind 

 tibiae with black hair on outer side ; abdominal segments with broad basal 

 fulvous hair-bands, a little black hair at sides of apical plate. Maxillary palpi 

 4-jointed; first joint large and stout, the others measuring in microns about 

 (2) 160, (3) 152, (4) 80. Hyaline area of maxillary blade transversely striated. 



Leptometria pacifica new species. 



Male. — Length about 9 mm. ; black, with the clypeus, labrum, and large 

 patch at base of mandibles light yellow; rest of mandibles dark reddish; an- 

 tennae long, the flagellum dark fuscous above, and pale reddish-testaceous 

 beneath, except at base; tarsi and apices of tibiae obscure rufotestaceous ; hair 

 of head, thorax and legs abundant, pale ochreous ; abdomen densely covered 

 with appressed warm ochreous hair; vertex shining; mesothorax and scu-
