.30. Larrada solstitialis. B.M. 



Female. Length 8-9 lines. — Black, and covered with a fine 

 silky silvery pile ; the face, sides of the scape, and base of the 

 mandibles covered with silvery pubescence which has a faint 

 golden tinge ; the thorax above has a similar clothing to the 

 face, most dense on the lateral and posterior margins of the 

 mesothorax and on the sides of the metathorax, the disk of the 

 latter transversely striated, its sides and also the truncation 

 coarsely so ; the truncation has a central longitudinal impressed 

 line deepest towards the verge of the truncation ; the wings flavo- 

 hyaline, their apical margins with a fuscous cloud, the nervures 

 and tegulse rufo-testaceous ; the posterior femora ferruginous ; 

 the spines which arm the ti^^ise and tarsi ferruginous. The 

 abdomen with changeable silvery fasciee on the apical margins of 

 the segments.

This species most closely resembles the L. suhtessellata, but 

 its metathorax is differently sculptured; the nervures of the 

 wings are also of a different colour. 



31. Larrada ciliata. B.M. 



Female. Length 5 lines. — Black : the face covered with sil- 

 very pubescence ; the tips of the mandibles ferruginous. Thorax : 

 the mesothorax and scutellum smooth, shining, and very deli- 

 cately punctured ; the metathorax transversely striated, the sides 

 of the disk and the truncation coarsely so ; the sides of the meta- 

 thorax obliquely striated ; the wings fuscous, their apical mar- 

 gins with a darker cloud ; the nervures and tegulae testaceous ; 

 the tarsi ferruginous, the anterior pair with long dark-coloured 

 flattened cilia, the spines which arm the intermediate and pos- 

 terior pairs long and black. Abdomen without fasciae : probably 

 in fine condition it would have silvery bands.
