of the genus, although possibly the red-banded species may not 
exactly belong to it. It is, however, impossible to deal 
exhaustively with the group until the genus WHemiteles has 
undergone a similar revision to that of Cryptus and Phygadeuon 
at the hands of Thomson. 
Hemiteles monospilus, described by Gravenhorst and Taschen- 
berg, is very much like the red-banded species in colour and size, 
but the description of the metathorax is very different from our 
insect. Taschenberg places it in a division having ‘‘ the meta- 
thorax elongated, without complete ares, the back part very 
oblique, almost confused with the upper part.’ In our species 
the two parts are of equal length and at almost right angles. 
CECIDONOMUS, hoy. gen. 
Head more or less globose; antennee filiform, shorter than 
abdomen. Width between the eyes and base of mandibles equal to 
width of base of mandibles. Thorax a little longer than high ; legs 
moderately slender ; wings with or without areolet, if present then 
pentagonal; posterior inferior angle of prediscoidal cell, acute ; 
metathorax with five more or less distinct aree, the supero-medial 
more or less subpentagonal; thorax alutaceous. 
Abdomen subpetiolated, depressed somewhat, apex more or 
less compressed, Ist segment gradually tapering, with tubercles ; 
aculeus about as long as the abdomen; abdomen about as long as 
the head and thorax and about as wide as the thorax, the widest 
part being at the apex of the 2nd segment. 
Cecidonomus Weston, n. sp. 
Length 4—6 mill., female. Black; head, thorax, and abdomen 
black, legs red, apex of intermediate sometimes deeper; apex of 
hinder femora, tarsi, and tibiz fuscous; this latter base and 
middle paler-banded. 
Head and thorax coarsely alutaceous, abdomen coarsely and 
closely punctured, punctures running into each other; metathorax 
coarsely wrinkled, arez distinct, supero-medial pentagonal with 
the lower sides shorter than the upper ones; areolet of wings 
pentagonal, transverse anal nervure divided below the centre; 
antenne about two-thirds the length of the body; aculeus a little 
longer than the abdomen. Male differs only in having the front
