rossii, never like ludlowii ; wing markings very variable, and may 

 resemble either species. 



Habitat. — Philippine Islands, taken at Bayambau, Mangarin 

 Guimaras Islands, etc. 



Time of capture. — May, September and December. 



Observations. — Miss Ludlow placed this as a variety of rossii. 

 It seems to me to be an intermediate form between rossii and 

 ludlowii, and as Miss Ludlow says, most nearly approaches rossii. 

 It occurs with ludlowii at random places in the Philippine Islands. 



A detailed description given by Miss Ludlow agrees in every 

 way with the specimens she sent me. 



So closely related are rossii and ludlowii that this inter- 

 mediate form makes one doubt as to whether they are not all 

 one species, but the general character of ludlowii and the fact 

 that its range extends to Malaya, makes me still retain indefinita 

 as distinct. 



It will be interesting here to see what properly described 

 larval characters will show, but these characters must not be 

 given in a slipshod way that has been done ; they must be noted 

 in adult larvae, or any way, in larvae of the same age. 



I have not seen anything like this variety outside the 

 Philippine Islands, and should not be surprised if it proved to 

 be a distinct species — indefinata.

 Note. — This spotted leg Myzomyia closely resembles rossii, 

 but it seems to be quite distinct.
