rest, and the only one of the group that is at all readily recognis- 

 able is Van der Wulp's annidaris, which has a distinctly lighter 

 wing than the rest and often shows fairly distinct banding of the 

 wing-fringe. In the Museum Monograph, all five forms are 

 separately described as sub-species, and figures of all but Indiensis 

 will be found on plate viii ; but personally I should prefer to re- 

 gard them as one moderately variable species. The only species 

 with which it can be confounded is Van der Wulp's An. barhi- 

 rostris, which, however, is easily distinguished by the palpi being 

 uniformly sooty black in both sexes, instead of banded. 



Mr. Theobald gives the following table of the differences 

 between these six forms, as follows : — 



A, Sinensis. 



1. Proboscis longer than palpi. 



2. White patch on border of wing 



below. 



3. Wing (costal) spots large. 



4. Scales elongated. 



5. Cross-veins close together. 



6. Border scales yellow. 



7. Apical fringe all yellow. 

 Length 4 to 5 mm. 



sub-sp. Indiensis. 



1. 1st sub-marginal cell with base 



near 2nd costal spot at the 

 junction of the sub-costal and 

 costal veins. 



2. Scales as in annularis. 



3. Cross-veins separate. 



4. Border scales yellow. 



sub.-sp. annularis. 



1. Palpi and proboscis equal. 



2. No white patch on border. 



3. Costal spots small. 



4. Scales as in type. 



5. Cross-veins separate. 



6. Border scales yellow. 

 Length 3-8 to 4-5 <?., 4 to 5 



?. 



sub-sp. pseiidopictus. 



1st sub-marginal cell with base 

 near 2nd costal spot at the 

 junction of the sub-costal and 

 costal veins. 



2. Cross-veins close. 



3. Scales as above. 



Length 5 to 6 miu, (often much 

 smaller). 



1. 



sub-sp. Nigerrimus, 



1. Base of the sub -marginal cell 



just in front of the costal spot. 



2. Apical frmge black. 

 Length 4"5 to 5 mm. 



A, barbirostris. 



1. Bases of the two fork-cells nearly 



level. 



2. Base of 1st sub-marginal cell 



not near junction of sub-costal 

 and costal. 



3. Scales broader. 



4. No white spot on lower fringe. 



5. Black apical patch to fringe. 



6. Palpi unhanded. 



7. Border scales black. 

 Length 5 nun.
