278 HYMENOPTERA. 



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

 reous pile ; the posterior femora bright ferruginous. Abdouen 

 covered with a fine silky pile, that on the posterior margin; of 

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

 lated aj)pearance; the apical segment opake, and having a levv 

 scattered ri2;id hairs. 



Hab. India; Sumatra; Java. 



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

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

 we have therefore given the name maura to another spe<-Aes. 

 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 /e?/iora^fl 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 transverselv 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. vigilans, but easily distinguished by the 

 sculpture of the metathorax. 



13. Larrada exilipes. B.M. 



Male. I^ength 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.
