THE ATHALIA GROUP OF THE GENUS MELIT^A. 195 



Trigona testaceinerva, sp. nov. 



Rufo-testaceous ; the head black, except the clypeus, labrum, 

 centre of face broadly, and a triangular mark (the narrowed end 

 above) between and above the antennse ; the base of mesonotum 

 suffused with fuscous ; wings clear hyaline, the stigma and nervures 

 testaceous ; the basal abscissa of cubitus straight, oblique, broken by 

 the stump of the recurrent nervure shortly below the middle ; the 

 cubitus obliterated beyond tlie recurrent nervure. Antennal scape 

 rufo-testaceous ; the under side of the flagellum of a darker rufo- 

 testaceous colour. The pubescence on the mesonotum and top of 

 scutellum fuscous, on the rest of the thorax it is denser and white ; 

 the hair on the legs white. ? . Length, 4 mm. 



Kucbing, Borneo (John Hewitt). A broad, ovate species. 



'Trigona pallidistigma, sp. nov. 



Testaceous ; the head above the antennae and the occiput fuscous, 

 the face and clypeus paler, the front more rufous in tint ; the legs 

 pallid yellow ; the scape of antennse rufo-testaceous, the flagellum 

 black ; wings hyaline, iridescent, the stigma and nervures pale testa- 

 ceous. ? . Length, 3 mm. 



Sarawak, Borneo (R. Shelford). 



Smooth and shining ; the hair on the head, body, and legs short 

 and white. The hind tibite become gradually widened from the base 

 to the apex, which is roundly curved ; the top closely fringed with 

 white hair. Hinder metatarsus wide, becoming gradually but not very 

 much wider towards the apex, which is rounded. 



Is allied to T. fmco-halteata, Cam., which may be known by 

 the black head and legs, and by the fuscous bands on the 

 abdomen. 



THE ATHALIA GROUP OF THE GENUS MELIT^A.

(Continued from p. 182.) 



Aurelia* was first definitely separated from athalia, and the 

 name given, by Nickerl in his ' Synopsis der Lepidopteren-fauna 

 Bohmens,' published in 1850. He does not, however, give any 

 concise description of it, but contents himself with mentioning 



-''• My argument that we apply the name athalia correctly is in no way 

 influenced by Mr. Eowland-Brown's criticism that aurelia is found at Fon- 

 tainebleau and Lardy, since Geoffroy distinctly asserts in liis preface that he 

 confines his remarks to insects taken within a walk of two or three leagues 

 of Paris, and in this sense of the word neighbourhood aurelia is, as I con- 

 tended, absent from the neighbourhood of Paris. I may here also remark in 

 passing that the paragraph on dictynna should obviously have preceded that 

 on partJienie.
