having a very long tongue, with entirely Panurgus-\\V.^ 

 labial palpi. Alloda-pe^ on the other hand^ has the labial 

 palpi wholly as in the ordinary long-tongued bees. 



It would seem, tiien, that Epeolas and Phileremus, with 

 tlieir allies, have been derived from the Panurgine series, but 

 from a higher type than Nomada. The resemblances we find 

 between Epeolus and the Anthophorina3 may be explained by 

 the probable fact that the Anthophoringe themselves iiavo a 

 Panurgine ancestry, though they have now travelled far 

 along their own special path. 



Melecta, Latr., 1802. 



Dalla Torre gives this as the first genus of the Nomadinn\ 

 It is parasitic upon Anthophora, as also is Crocisa. \\\ 

 Melecta miranda we find the maxillary palpi very small, five- 

 jointed, the last joint minute; the galea is very large, witii a 

 few short dark spines at the apex ; the tongue and the labial 

 palpi are of the type usual in long-tongued bees. In Antho- 

 phora montana we find the third joint of the labial palpi 

 attached laterally some distance before tiie end of the second, 

 at about the middle of the terminal narrowed ])ortion of the 

 second joint. Tlie outer side of the two first joints is 

 covered with bristles, which form a brush at the end of the 

 second. In Epeolus and Melecta the last two joints are 

 attached at the end of the second, as also in Melissodes and 

 Xenoglossa. In Epeolus, however, the second joint is not 

 narrowed apically, whereas in Melecta miranda it is greatly 

 narrowed, with the narrowed portion largely hyaline. The 

 galea of Anthophora montana has the same general form as 

 that of Melecta miranda, but is distinguished by numerous 

 strong bristles scattered over its surface. Much more similar 

 to that of Melecta, when one goes into details, is the galea of 

 the series of Melissodes &c. Thus in Xenoglossa pruinosa we 

 find on the apical part of the galea a longitudinal series of 

 bristles having tubular sockets, wiiile the margin of the galea 

 behind these bristles is abruptly narrowed and hyaline. The 

 same row of bristles appears in the Melecta, but it is longer 

 and the long hyaline area is not narrowed. In Melissodes 

 pallidicincta the liyaline area is extremely small, but recog- 

 nizable in comparison with the other genera. 



From the above facts we must apparently conclude that 

 Melecta is really derived from the Anthophorine series, but 

 not from Anthophora itself.
