Senoprosopis meridionalis, sp. nov. 



Face yellowish- white. Antennae black in both sexes. 

 Bristles of the epistome yellowish- white, with a row of 

 black ones above. Thorax yellowish-brown above, with two 

 longitudinal bands and some spots outside them dark-brown ; 

 the sides yellowish-brown, with few hairs. Abdomen almost 

 hairless ; the first three segments yellowish-brown with dark- 

 brown rings, the posterior segments dark-brown. Halteres 

 dark-brown. Wings greyish ; veins black. Legs reddish- 

 brown, the upper surfaces of the femora and the tarsi dark- 

 brown ; the hairs yellowish, the bristles black ; some long 

 hairs on the fore femora and tibiae. Length, $ 12 mm., 

 $14 mm.; wing, <? 6^ mm., ? 8mm. 



Hab. Christchurch (H. Clark). 



In addition to the colours, the antennae differ from those 

 of the last species in having the first joint shorter in the male, 

 and in the second joint being as long as the first. 



Family BOMBYLID^. 



" Three basal cells much prolonged ; anterior intercalary 

 vein present, almost without exception ; the posterior always 

 wanting. Third joint of the antennae simple [ empodia quite 

 rudimentary " (Loew). 



Genus Fraudator, gen. nov. , 

 Eyes contiguous, the facets coarser above than below. 

 Face not projecting. Antennae approximated at their bases ; 

 first and second joints short ; the third much longer than the 

 other two together, swollen near the base and gradually taper- 

 ing to a long point, glabrous. Proboscis short. Abdomen 

 narrow-linear. Tibiae without spurs ; no empodia. Third 

 longitudinal vein branched near the end ; no posterior inter- 

 calary vein ; third basal cell closed, petiolate. 



I include this genus in the Bombylida on account of the 

 absence of the posterior intercalary vein, but it is very differ- 

 ent in appearance from the other members of the family, 

 having a superficial resemblance to Heleodromia fumosa. In 

 the neuration of the wing it resembles Oncodocera (Macq.), 

 but that genus has the abdomen broad and oval. 



Fraudator perspicuus, sp. nov. 

 Eyes piceous ; antennae black. Thorax black, with a 

 tawny patch on each shoulder ; the posterior portion and 

 scutellum yellowish, the sides silvery. Abdomen dark-brown, 

 with scattered white hairs. Halteres white. Wings smoky, 

 a clear patch just outside the stigma, which is large ; fork of 

 the third longitudinal vein leaving at a very acute angle, then 

 curving forwards and joining the margin nearly at right angles ;
