278 HYMENOPTERA. 



the sides and beneath, and also the legs, have a fine silky cine- 

 reous pile ; the posterior femora bright ferruginous. Abdomen 

 covered with a tine silky pile, that on the posterior margins of 

 the segments silvery; in some lights, the abdomen has a tessel- 

 lated appearance; the apical segment opake, and having a few 

 scattered rigid hairs. 



Hab. India; Sumatra; Java. 



This is quoted by Dahlborn as the Liris maura of Fabricius, but 

 that author does not mention the silvery pile on the abdomen ; 

 we have therefore given the name maura to another species. 

 Dahlbom also gives Australia as the locality : the only species 

 from that country agreeing with the description of Fabricius is 

 quite distinct from the present insect, and appears to be one of 

 the varieties of the femorata of Saussure. 



12. LARRADA LABORIOSA. B.M. 



Female. Length 5-6 lines. Black : the face has a thin silvery 

 pubescence; the mesothorax and scutellum shining, very deli- 

 cately punctured ; the metathorax very finely transversely rugose, 

 the truncation more strongly so ; the sides of the metathorax 

 delicately obliquely strigose ; the disk has an abbreviated longi- 

 tudinal carina, and the truncation a deeply impressed line ; wings 

 smoky hyaline, the nervures black ; the legs thinly covered with 

 sericeous pile. Abdomen covered with a fine changeable pile ; 

 that on the apical margins of the segments bright and silvery, 

 but only observable in certain lights. 



Hab. Philippine Islands. 



Closely resembling L. vigilant, but easily distinguished by the 

 sculpture of the metathorax. 



13. LARRADA EXILIPES. B.M. 



Male. Length 3^ lines. Black : covered with short change- 

 able silvery pile, which is most dense on the sides and apex of 

 the metathorax and on the apical margins of the segments of 

 the abdomen ; the face with a dense bright silvery pubescence. 

 The metathorax irregularly transversely rugose, with some coarse 

 grooves at the sides and on the truncation, which has in the 

 middle a deeply impressed fossulet ; the wings hyaline, with the 

 apical margins slightly fuscous ; the nervures and tegulse rufo- 

 testaceous ; the posterior femora bright ferruginous ; the legs 

 slender and elongate. 



Hab. Northern India. 



This is probably the male of L. subtessellata.
