The male is very slender, cylindrical, smooth, pale lu- 

 teous buff. The antennae are rather longer than the fore 

 femora. The mesothorax is marked with two very fine 

 black lines down each side. The tegmina are small, nar- 

 rowly ovate, pale luteous-coloured, areolated, with small 

 black dots enclosed in the areolae. The wings are minute, 

 steel-blue and glossy ; the costal area greenish at the ex- 

 tremity with black dots, sanguineous at the base. The ab- 

 domen is slender (the three terminal segments are wanting 

 in the unique male in the National Collection) ; the basal 

 segments have a rudiraental lobe almost indistinct in the 

 middle of the hind margin of each. The legs are long and 

 slender, the four hind ones finely serrated on the under 

 side of the femora. 



The female is more robust and brown, with the meso- 

 thorax and abdominal segments granulose ; the tegmina 

 and wings are coloured as in the male ; the middle of the 

 central abdominal segments is more distinctly lobed ; the 

 terminal segment is slightly notched in the middle, with 

 the two very short thick anal styles visible at the sides. 

 The operculum scarcely extends beyond the base of the 

 ninth dorsal segment. The legs are shorter and more ro- 

 bust ; the four hind femora are more strongly serrated on 

 the under edge.

Elongata, gracilis, subparallela, lutea, laevis, impunctata ;

This species agrees so entirely in all respects, size in- 



cluded, with the females of Bacillus Peristhenes, that I 

 was, at first, tempted to believe that the unique speci- 

 men in the British Museum Collection was one which had 

 acquired an extra development in its transformations. The 

 abdomen is attenuated from the base to the apex, where it 

 is furnished with a pair of anal styles as long as the eighth 

 and ninth dorsal segments ; it is of a luteous colour, smooth, 

 impunctate, but not glabrous. The head has a rather deep 

 impression between the eyes. The mesothorax is finely 

 granulated, and furnished at its hinder extremity with a 

 pair of minute oval tegmina. The metathorax is also fur- 

 nished with two minute rudimental wings, extending a very 

 short distance beyond the extremity of the tegmina. The 

 four hind femora arc armed beneath, between the middle 

 and the tip, with two to four minute spines ; the tibiae are 

 slender and simple. The operculum is small, scarcely ex- 

 tending beyond the middle of the eighth dorsal segment. 

 The antennae and two fore legs are wanting in the single 

 female specimen which I have examined.

Note. — The reference made, in p. 1 3, of this figure to the 

 female of Bacillus Peristhenes must be expunged.

Fusca, albido granulosa, lineisque elevatis gracilibus lon- 

 gitudinalibus ornata ; capite tuberculis duobus parvis nigris 

 inter oculos ; antennis perbrevibus, circiter 15-articulatis ; 

 mesothorace spinis paucis irregularibus armato ; tegmini- 

 bus alisque brevissimis rudimentalibus ; abdomine e basi 

 ad apicem sensim attenuato, apice integro ; pedibus medio- 

 cribus, femoribus anticis crassioribus, antice 5 aut 6 spinis 

 serrulatis, quatuor posticis prope apicem spinis 2 aut 3 mi- 

 nutis instructis (fcem.).

Brown, covered with minute whitish granules, and 

 marked with slender raised longitudinal lines. The head 

 with two small black tubercles between the eyes. The an- 

 tennae not twice the length of the head, about 15-jointed ; 

 the basal joint broad, ovate and depressed. The meso- 

 thorax is armed with several irregular spines. The tegmina 

 and wings are very small and rudimental. The abdomen 

 is gradually narrowed from the base to the extremity,
