attenuated, sometimes effaced ; 1st cubital areolet imperfectly 
separated from the 1st discoidal ; 3rd abscissa straight ; pobrachial 
areolet of the hindwings rather longer than half the prsebrachial. 
Legs rufous ; tips of the hind tibee often obscure. First abdominal 
segment twice as long as its apical width, irregularly striolate. 
Terebra as long as the vertical truncature of the abdomen at its 
extremity. ^ Similar ; antennge SO-jointed. Length, If ; wings, 
4 lines. 
Vae. $ . Antennae somewhat shorter, as long as the body, only 
25-iointed, the two basal joints rufous, and the flagellum obscurely 
ruf esceut, blackish towards the extremity. Differs from fulvicornis 
(sp. 2) in that the 3rd cubital areolet is not four times as long as 
the 2nd. 
This probably constitutes the genus Dinotremaj 
Forster, characterised as having the " Luftlocher des 
Metathorax mittelgross, deutlich.-'^ It is too common an 
insect to have escaped the notice of Haliday, and seems 
to be included among the varieties of sp. 56 (Ent. Mag., 
v., 245) without a name, but afterwards called nervosa 
(sp. 9, infra). This latter differs constantly in being 
much smaller, with stouter antennae, shorter than the 
body, and having fewer articulations, etc. I have seen 
hundreds of the real nervosa, bred all together, and am 
therefore somewhat familiar with its appearance. A. 
prsecipua is generally distributed, but less abundant than 
nervosa.

5 . Black or piceous-brown, shining ; mandibles rufous. 
Antennae 15-19-]'ointed (according to Haliday also 13-jointed), 
fuscous with the 3 basal joints rufous, hardly shorter than the 
body. Dorsal fovea of the mesonotum punctiform, often obsolete; 
metathorax very finely rugulose. Wings much longer than the 
abdomen, hyaline ; squamula testaceous ; nervures very pale 
brownish ; 1st cubital areolet separated from the 2nd, and from the 
1st discoidal ; 2nd cubital areolet elongate, narrow, slightly con- 
tracted towards the outer end ; radial areolet longer than half the 
wing. Legs testaceous. First abdominal segment almost linear,
