which have been used in the past and have noted which additional 
characters I feel should be carefully evaluated in future descriptive 
and taxonomic work with this family. 
The Genus Sphaeroberotha 
Navas based his description of the type species of Sphaeroberotha , 
S. dumonti, on a single female. Although he included the species 
Costachella geyri (Esben-Petersen) in his new genus as a second 
species, his characterization of Sphaeroberotha was, in fact, based 
almost solely on S. dumonti since he had only a drawing, whose ac- 
curacy he questioned, of the wings of Esben-Petersen’s species for 
study. Through the great kindness of Dr. S. Kelner-Pillault of the 
Museum National d’Histoire Naturelle, Paris, I have been permitted 
to borrow and study the holotype of S. dumonti from which the 
following redescriptions and discussions are drawn.

Description. A genus belonging to the Berothinae. Face short, 
extending only slightly ventrad of eyes; vertex a slightly raised tri- 
angular area, with two weak lateral tubercles at its posterolateral 
corners; postgenae moderately inflated. Scape only slightly elongate; 
antennomeres distal to scape subspherical, each with two rings of 
distally directed setae which extend as far as the next antennomere; 
distal antennomere more elongate, acuminate. Mouthparts well de- 
veloped, mandibles with tips crossing when jaws are closed. Pronotum 
moderately robust, slightly wider than long, with two transverse 
furrows, strongly deflexed laterally. Fore legs lacking raptorial 
modifications. 
Wings (Fig. i) elongate, with rounded tips, lacking any indica- 
tion of falcation; Sc connected distally to Ri by an oblique cross 
vein at edge of pterostigma; two radial cross veins; free basal piece 
of MA (Fig. i, b) oblique, slightly proximal to basal fork of MP; 
a weak series of outer gradate crossveins present. Fore wing: prob- 
able vestige of recurrent humeral vein present basally in costal cell 
as a steeply inclined crossvein with a distal fork; stems of M and R 
fusing just proximal to basal subcostal crossvein; outer gradate 
crossvein between the branches of MP generally in line with gradates 
above and below this vein, not far proximal to these; jugal vein and
