apically, and with hairy margins; its dimensions in /i are: 

 (1) lengtli 1530, (2) breadth at base 1105, (3) breadth at 

 apex 900. CUwvs bifid, with the inner tooth much the 

 smaller and shorter, precisely as in Bomhus. 



Wings clear, with pale nervures ; length of anterior wing 

 about 8^ mm. 



Length of body about 15 mm. 



The following measurements of the anterior wing are 

 in ytt : — 



J^euotli of marginal cell 2380 



Depth „ „ 595 



Lengtli (obli(|uely) of" first submarginal 1020 



„ of second submarginal 765 



„ of third „ 1020 



Second submarginal on marginal 3 10 



Third „ „ 510 



Second submarginal on first discoidal 391 



,, „ third „ 459 



Third „ .".>'. ^^^7 



Height of third submarginal in middle 425 



Insertion of second r. n. to appendicular uervuro at 



end of third s.m 170 



Length of first discoidal cell (obliquely) 2312 



„ of transverso-medial nervure 255 



Width of second discoidal cell at apex 765 



Length of basal nervure 1836 



The transverso-medial is vertical except at its upper end, 

 where it bends basad and actually meets the basal. This 

 band is easily overlooked, giving the impression that tlie 

 nervure ends a siiort distance apicad of the basal. 



In the above table of measurements the first and third sub- 

 marginals appear of equal length ; but if measured in the 

 same manner, i. e. from the middle of the basal to the middle 

 of the apical side, the tliird is much the longer. 



The new specimen is on a slab with various leaves ; a leaf 

 of Fagus longifoha (Lx.) is less than an inch from tlie bee, 

 and a leaflet of Weinmannia phenacophylla, Ckll., is equally 

 close. 



This species is of great interest to me, because I have just 

 been studying the ancestors of the Bombidaj in Baltic amber 

 of Oligocene age. The amber materials, kindly loaned from 

 the j\luseum at Konigsberg through Dr. A. Tornquist, throw 

 a flood of light on the subject, including as they do numerous 

 genera and species in a wonderful state of preservation.
