182 GROTE & ROBINSON. 



concolorous with anterior wings. Abdomen darker, blackish. The 

 preanal segments pale yellowish. Anal tuft black, divided. Anal 

 segment with black tufted scales. Beneath, the palpi are white, and 

 the under thoracic surface is white mixed with slaty grey. Legs 

 finely scaled, slight, obscurely colored. Anterior tibiae with an ex- 

 ternal row of short black spinules; anterior tarsi also spinose. 



Primaries dark at base, where there are a few paler scales. A 

 double black transverse line. The middle of the wing is concolorous 

 with the thorax above. A discal black abbreviated line. Below the 

 third median nervule this line is continued to internal margin. A 

 faint sinuate line before the extremity of the middle field of the wing; 

 this paler middle of the wing is limited by a deeper and diifuse blackish 

 line coincident with the first and faint transverse line. Outside of this 

 deeper line the terminal portion of the wing is obscurely darker than 

 centrally ; i'ringes tinged like the paler ground color of the wing. 

 Secondaries black at base, with a very broad, pale yellowish white 

 median band, and a deep black even terminal band. Fringes yel- 

 lowish white. Beneath, the primaries are whitish, the veins darker, 

 terminal space darkly shaded. Secondaries yellowish white, except a 

 terminal black band.

Habitat. — California. 



We redescribe here this peculiar little species, one of the smallest 

 of the family, from material received through the kindness of Dr. 

 Boisduval. The genus is allied to the European Macroglossum, and 

 the comparatively minute form is our nearest approach to the European 

 M. stellatarum. We have elsewhere wrongly compared it with Proser- 

 pinus. There is a great disproportion between the wide triangulate 

 primaries and the reduced secondaries. 



The present description should supercede that given by us as noted 

 above, and which was made from a colored drawing of the species, 

 and is necessarily inaccurate in detail. 



Family AEGERIIDAE.
