284 Mv. T. J. Evans — Bionomical Observations 



roesothorax and scutellum with black hair, but some white in 

 the suture between them and just behind teguhe ; much long 

 white hair behind scutellum, and a white tuft below tegulaa ; 

 hair of upper part of pleura black, the rest white ; tegulse 

 dark rufo-fuscous. Wings strongly infuscated. Legs dark 

 rufo-fuscous, with black and white hair, that on inner side of 

 tarsi rufo-fulvous ; anterior tarsi simple, but rather thick; 

 anterior and middle tarsi with a fringe of long hair behind ; 

 hair on outer side of hind tibiae glittering white. Abdomen 

 rather short, the second and third segments constricted 

 apically ; first segment with white hair fringing the basin and 

 black hair just behind ; first three segments slightly rufes- 

 cent, each with a very narrow, rather inconspicuous, apical 

 hair-band, which widens laterally on first into a white patch, 

 and on the others into a large long-triangular patch, which is 

 suffused with yellowish ; similar patches are seen at sides of 

 fourth segment ; sixth segment rather obtusely bispinose. 



Related to M. rhodura, Ckll., but much more robust, with 

 the abdominal punctures less dense and very much smaller, 

 the wings much darker, &c.

Localities of Mexican Bees. 



In paper XXVI. of this series, I described certain Mexican 

 bees in the Berlin Museum, the precise localities of which 

 were in doubt. The following information received from 

 Mr. E. Strand will help to elucidate the matter : — 



(1) Ferdinand Deppe sent to the Berlin Museum in 1829 



specimens from the following localities :— Temascal- 

 tepek ; Real Ariba ; Oaxaca ; Vallereal ; Rio Alvarado. 

 Some of the bees, at least, were from Oaxaca, and 

 very likely all came from there. 



(2) Alphonse Forrer collected in the high plateau at 

 8100 ft. in the vicinity of Durango, Mexico (Durango 

 City = Ciudad Durango). The citation California on 

 the labels is an error. 



XXX. — Bionomical Observations on some British Millipedes. 

 By T. J. Evans. 



The following observations deal with the habits, and espe- 

 cially the breeding- and moulting-habits, of some of the 

 British Millipedes, viz. Olomeris marginata, Polydesmus
