with a row of bristles above from middle to tip, diminishing in size, 

 a row on outer side on basal half, replaced towards the tip by 

 moderately soft, rather long hairs ; a row of about i6 to i8 com- 

 paratively strong bristles on under side, extending the whole length 

 of the femur, and equal in size. Middle femora with some bristles, 

 lying rather flat, on front side; two contiguous, moderately strong, 

 slightly curved bristles above, near tip, and a row of bristly hairs 

 on under side. Hind pair with a row of bristles on front side, a 

 single curved bristle below near tip. Knees tawny, the colour ex- 

 tending sometimes over the whole basal half of some of the tibise ; 

 tips of tibise with 2 or 3 short spines. Tarsi blackish, under side 

 with a little gold-yellow pubescence, which is sometimes lightly 

 present on inner side of anterior tibiae. Pulvilli dirty white. 



Wings. Practicalh' clear, but in the a' sometimes slightl}' 

 tinged with brown on basal and front parts ; ist posterior cell 

 widel}' open, the 4th vein forming a well rounded loop at the bend 

 upwards ; apical portion genth^ curved. Outer cross- vein normally 

 with one gentle inward curve, variable, at times nearly straight, 

 or nearly bisinuate. Tegulse yellowish white. 



Described from a long series of specimens of both sexes in the 

 Indian Museum collection and my own, and also from European 

 specimens. It is practically one of the world-wide species that 

 occurs wherever civilised man is found, and in at least the East 

 it is apparently present all the 3'ear round in every locality. Actual 

 dates would therefore be hi little significance. It is in the Indian 

 Museum collection from Gangtok {Sikhim), Sylhet, Kurseong 

 (Darjihng), Mussoorie, Simla, Calcutta, Port Canning, Puri, Berham- 

 pur, Bhogaon, Travancore State (S. India), Rajmahal (all India) ; 

 Colombo, Rangoon, Kawkareik (lyower Burma), Mandalay, and 

 from on board ship, at light, off Tuticorin. Personally I have 

 met with it in many parts of the Punjab, Mussoorie, at Rangoon. 

 Singapore, Penang, and other places further East, and have it from 

 Java, Ceylon and the Philippines. 



N.B. — The above lengthy description has appeared advisable 

 from the variability of this very common species. Further varia- 

 tions and combinations of the differences (mostly in the abdominal 

 markings) above stated, occur in individual examples, and as the 

 species has already been described under no less than 17 different 

 names, I hesitate to regard as distinct any form which appears to 

 fall within its possible range of variation ; especially as I have seen 

 no distinct '' variety," " race," " form," or " subspecies " 

 ])eculiar to any .special locality and illustrated by any number of 

 consistently marked specimens.
