what broad lobe. There are only three species in this genus, two of 

 which occur within the Province. Its range in British Columbia is 

 from Vancouver Island to the Kootenays, and it occurs right across the 

 continent to the New England States, where it is quite common. It 

 feeds upon various plants of the order Rosaceae but does not confine 

 itself to these, as it will feed upon willow, poplar and other forest trees. 



(7) 708 Paonias myops Ab. & Sm. (The Small-eyed Sphinx). 

 This is a smaller species than the preceding and somewhat prettier in 

 ornamentation. The food plants and localities are much the same as 

 excaecatus but it is much less common. It is rather rare in British 

 Columbia and has been reported from the Okanagan District and from 

 East Kootenay. I do not think that it occurs on Vancouver Island; 

 so far I have not seen it in any collection on the Island. 



(8) 711 Pachysphinx modesta R. & J. This species has two pop- 

 ular names, the Modest Sphinx in allusion to the quiet modest tints in 

 which it is clothed, and the Big Poplar Sphinx on account of poplar 

 being its chief food plant, although it will also feed on willow. It- is 

 the largest of our local sphingids, measuring from 4 to 5 inches in wing 

 expanse. The body and basal third of the fore wing is pale olive, with 

 the outer third of the wing a darker olive and the middle third darker 

 still with a minute olive discal dot. The hind wings are dull carmine 

 red in the centre with a bluish grey patch near the anal angle. The 

 larva when full grown is about 3 inches long, of a pale green colour 

 and coarsely granulated, the granules studied with fine white points, 

 giving it a frosted appearance. This species is recorded from the 

 Okanagan to the foothills of the Rockies, but is somewhat rare. Out- 

 side of the Province it extends to the Atlantic coast and southwards into 

 the northern portion of Mexico ; but is not common in any locality. 



(9) 732 Haemorrhagia thysbe form cimbiciformis Steph. (Hum- 

 ming Bird Clearwing). This section of the Sphingidae differs from all 

 others in having the middle of all the wings transparent, that is, free 

 from scales. In many species the abdomen of the male ends in a fan- 

 shaped anal tuft. 



In our 1906 "list," thysbe is listed from the coast, but I have never 

 been able to trace the specimens that the record refers to. The insect 

 that occurs in British Columbia is the form cimbiciformis and it differs 

 from thysbe in the outline of the inner margin of the broad outer band 

 of the primaries ; in our form the line is even or slightly sinuate, in 

 thysbe the line is strongly dentate. It is the rarest Hawk Moth that 

 we have in the Province, I only know of three specimens being taken, 

 although there may be others of which I have no record. The speci- 

 men shown was taken in the Bulkley Valley in June, 1914, and the late 

 Wolley Dod records one taken at Field in 1909. Strange to say, it is 

 the commonest species ■of the genus in Eastern Canada and the New 

 England States. The larva feeds on viburum, honeysuckle and snow- 

 Ijerrv.
