268 THE CANADIAN ENTOMOLOGIST. 



of the legs than in those I took in Batan in 1901, or in those taken in 

 Abra, and which were sent to Mr. Theobald for identification. In these 

 earlier specimens the yellow spots on the legs are practically confined to 

 the femora, tibi^ and metatarsi, and this is the case in many specimens 

 still sent in, but in the collections referred to the spots extend well on to 

 the tarsal joints, so that the last two are often the only ones lacking them- 

 The femoral spots are in some specimens nearly white, and all of the legs 

 are marked, the fore legs as prominently as the others. This difference is 

 so noticeable as to be misleading, but there can hardly be doubt that, as 

 the insect in other respects corresponds closely to Ludiowii, it must be 

 regarded as merely an individual variation, not even worthy of place as a 

 "variety." 



Some of the specimens of jEdeomyia sgiiammipenna, Arribalzaga, 

 coming from the P. I., show marked variation from the type, and yet, as 

 these differences vary, can only be counted as individual differences j the 

 palpi in some specimens have ochraceous instead of white scales near the 

 base ; the wing markings vary much as to size, and, incidentally, a little 

 in position ; the white leg-bands are often broader, and the distal tarsal 

 joint on the hind leg is frequently pure white. Of course, if these 

 differences ran true, they would suggest a new species, but as they do not, 

 are only of general interest. 



Some time since my attention was called to a general resemblance 

 between Tceniorhynchus argenteus, mihi, and Culex gelidus, Theobald. 

 1 have therefore compared the two carefully and find the following 

 differences : As to proboscis, C. gelidus yellow, with a brown band near 

 the apex ; T. argenteus brown, with broad white band. As to thorax, 

 C. gelidus has a heavy white marking extending about two-thirds the 

 length of the dorsum, the caudad third being of the yellowish-brown of 

 the scutellum. T. argenteus has the white marking extending over the 

 whole mesonotum and scutellum, with the exception of two oblong spots 

 near the caudad end of the mesonotum. These seem to differentiate the 

 insects, and there are besides these some scale differences which seem to 

 throw it into Tceniorhynchus instead of Culex. 



Megarhinus LeWaldii, mihi, to conform to the binomial nomenclature, 

 must be written M. Lewaldii. 



Long study and acquaintance with Afyzomyia Rossii, var. indefinita, 

 mihi, has convinced me that it should never have been referred to Rossii, 

 and that it must stand as a distict species — indefinita, Ludlow.
