338 THE ENTOMOLOGIST. 



serve to distinguish them ; then again they have usually all 

 the tarsi pale, and frequently the legs entirely so ; the mar- 

 gins of the abdominal segments are bordered with a black 

 line ; the joints of the antennae are not so decidedly monili- 

 form, and the apical half of the mandibles is usually pale 

 rufescent. In my worl; on the * Bees of Great Britain ' 

 I quoted Andrena PotentillEe as synonymous : this was an 

 error, which my friend Dr. Sichel has corrected : Panzefs 

 insect is undoubtedly the male of Andrena analis. I cannot 

 regard S. hispanica, with Dr. Sichel, as the same as our 

 insect : 1 have received a series of that species from Algeria, 

 and consider it quite distinct. Dr. Sichel has drawn atten- 

 tion to the diagnosis of the Linneau Sphex ephippia, " Alra, 

 fronte caerulescente, abdomine fascia ferruginea duplicata." 

 I have again re-examined the typical specimen in the Lin- 

 nean cabinet, and can vouch for the head being entirely 

 black. The error is obvious : " caerulescente " should have 

 been " pubescente," — an error doubtless of the press. Sonie 

 doubt having been expressed of the propriety of adopting 

 the Linneau name, I give this explanation of the circum- 

 stance ; and 1 would also refer to the full and correct descrip- 

 tion by Linneus, in these terms, " Fronte pilosa, ex albo 

 micans." This elucidation will, I trust, remove all doubt on 

 the subject.

 This species is included with some degree of doubt. There 

 are two specimens in the British Museum, believed to have 

 been taken in Devonshire by Dr. Leach, and I possess two 

 said to have been captured near Bideford.
