Labrum with a moderate or rather shallow notch, with the setae 

 i and ii only half as far apart as the setae i are from each other 

 (thus agreeing with the preceding genera rather than with 

 Hemaris). Supraanal an equilateral triangle; joints of antennae 

 nearly equal in diameter. In the next to last stage flavofasciata 

 at least, has a horn similar to that in adult gaurce. 



Macroglossa. Head and body nearly smooth, but marked 

 by slight raised white tubercles. Head very small and round, 

 the body sharply tapering toward it. Horn normal, longer 

 than height of head. Adfrontals -J height of front in width. 

 and with seta i higher than the top of the front. Third, fourth 

 and lower ocelli evenly spaced, and very close together, nearer to 

 each other than to the posterior. Front | height of head ; dis- 

 tance between seta? i and ii of labrum § that between the 

 two setae i. True legs single-colored; spiracles red with white 

 spots at the two ends. The genus shows likenesses to Hemaris on 

 the one hand especially to H. croatica, which is very similar; and 

 to the Darapsa group on the other, rather than to Proserpinus. 



Hemaris (Haemorrhagia). Head rough and tuberculate; 

 cervical shield, etc., also rough, and skin generally with more or 

 less distinct raised tubercles. Horn moderate, or long and 

 slender. Front I height of head. Otherwise as in Macroglossa, 

 even as to the coloring of the spiracles. The species I have seen 

 make a very good graded series, from Macroglossa to //. thysbe. 



H. croatica. Cervical shield no rougher than head, without 

 any distinct anterior ridge; lower ocellus close to the next one 

 as in M. stellatarum. Legs without any black. Head regu- 

 larly rounded, not distinctly higher than wide. 



H. rubens. Head and cervical shield with fine granulations 

 separated from each other by about twice the diameter of a 

 gramxlation, except toward the anterior edge of the cervical 

 shield, where they are nearly in contact, and in a single even row. 

 Front, and head as a whole higher than croatica, agreeing with 

 the following species. Feet with a little black on the front of 

 the coxa? only. Horn rather short. 



H. diffinis (typical). Cervical shield with the granules 

 no larger than in H. rubens, but with the surface of the shield 

 raised into ridges, so as to appear much rougher, considerably 

 rougher than the head. The granules on the anterior edge 

 make a ridge, but they are not confluent and the ridge is not 

 well defined. The true legs have the femora marked with 

 deep black brown.
