Abdomen smooth ; the basal two thirds of the basal segment, the 

 greater part of the fifth, the apex and the ventral surface are 

 reddish fidvous. 



JNToMiA (Paranomia) pulchribalteata, sp, nov. 



Nigra ; capite, thorace i^edihusque dense griseo-hirsutis ; ahdoniinis 

 segmentis virido-mnrginatis ; alisfere hyalinis, sHgmate nervisque 

 nigris ; postscuteUo spinis duabits armatis. S et ^ . 

 Long. 8-9 mm. 



$ . Scape of anteunae sparsely covered with pale hair. The 

 vertex and the sides of the face are thickly covered with griseous 

 pubescence ; the pubescence on the other parts is much sparser. 

 The lower part of the vertex, the face, and the clypeus have a 

 distinct keel down the middle ; the face is punctured, except in 

 the centre ; the clypeus is closely, irregularly, longitudiually 

 striated ; its sides and apex are bordered by distinct keels. The 

 base of the mandibles in the centre is rugose, and bordered above 

 and below with keels ; the apex of the mandibles is oblique. 

 Mesonotura and scutellum closely punctured ; the scutellum is 

 slightly depressed in the middle ; the post-scutellum is armed with 

 two spines, which are stout, straight on the inner side, rounded above 

 on the outer. The basal area of the median segment is longitudi- 

 nally sti'iated ; the strise are more widely separated in the centre 

 than at the sides. The legs are thickly covered with griseous 

 pubescence ; the calcaria are dark rufous ; the scopa has white, 

 mixed with longer, black hairs. Abdomen shining ; the basal four 

 segments banded with green, mixed with yellow on their apices : the 

 basal band is narrower than the others ; the segments are closely 

 punctured except at the apex ; the basal is covered with white, the 

 apical segments with longer, black hair ; the ventral segments are 

 thickly covered with white hair. Median segment at apex closely 

 punctured, except for a triangular smooth space at the top. 



The 1^ is similarly coloured ; the scutellum has the sides obliquely 

 narrowed, and ends laterally in a short tooth ; the scutellar spines 

 are longer and narrower than in the $ ; the hinder femora are 

 greatly swollen ; on the basai part above are two curves, the basal 

 being the shorter and straighter ; the tibiae are thickened, and broadly 

 rounded on the outer side, the apex on the inner side is oblique ; 

 the greater part of the tibiae behind, their apex, and the base of 

 the tarsi are fulvous ; the tarsal spines are rufous. 



NOMIA METALLICA, Sp. nOV. 



S . Long. 7 mm. 



A species easily known from JSl. pidclirihalteata by its smaller 

 size, by the head and thorax having brassy metallic tints, by the 

 head in front not being keeled, and by the abdomen not being 

 banded with greenish yellow. 



Antennae black ; the flagellum brownish beneath. Head black, 

 with distinct brassy tints ; thickly covered with griseous pubes- 

 cence ; closely and distinctly punctured, except in the centre of
