Andrena stands under several names in Kirby's collection, as detailed 

 below. Kirby's No. 113 is a (^ of N. fabririeUa, but it was not added 

 to the typical specimens of his Apif< qnadrinnfata, this being the name 

 under which he described tlie male oi fahriciella, though he suggests 

 that it may be the other sex of the list named. The type of A. riifocincta 

 is -A Jiavoguifahi $ , wot furva Panz., as Smith considered it. 



In the genus ^//(7re//o, of Kirby's Mellfta rosae Panz. (No. 39), 

 the specially numbered ? is what we have considered to be Panzer's 

 species (s. str.). " 39 '^ var." is -a. f area ? . as also ai-e y and 8; the 

 .' cJ" is that of fovea. MeJitta zonalls (No. 40) is the true ^ of rosae. 

 Under M. nitida K. the example labelled "51 ? var." is a mutilated 

 trinimerana $ ; the lettered varieties are correctly placed. The males 

 assigned to tibialis, the one headless and the other var. /3 are both 

 A. nigronenea, but these males are not described in the " Monographia." 

 M. iiiouffeteUa K. (53) as Saunders correctly determined, is a very 

 ordinary, stylopized ^ of fibiaJi.^, and the males are also that 

 species. 



Melitta trinimerana K. (No. 57) is a cause of difficulty. The type, 

 as was obvious at a glance, is not what is universally known as Andrena 

 trinimerana K., but is the $ of the summer brood of A. spiniriera K., 

 known to us as ^. anylica Alfk. When we consult the " Monographia" 

 (II, p. 116) we find that Kirby only once collected typical trimmerana, 

 and that was in the middle t)f August. He says " Hab. Barhamiae in 

 Jtorihwi Augusto medio 1799 sequel Jecta, /3 6i> in floribna Jiorti mense 

 Maio. Capta etiam a D. Jaoho Trimmer " 



This sufficiently shows that the type form of trimmerana was not 

 what we know by that name. It is true he says that the scopa is 

 " iinbtns aJhida,'' i.e., whitish beneath, a character of the trimmerana 

 of our lists, but if he examined typical examples of this latter from 

 Trimmer, as is quite likely, he may well have supposed that the scopa 

 was slightly discoloured in his own specimen ; indeed, it frequently 

 becomes so from pollen. Kirby seems to have had little knowledge of 

 our common trimmerana, for he assigns his one (^ of it to A. varians. 

 It seems clear then, deplorable as we must consider it, that A. .yjiiiigera 

 K. (No. 63) must be known as A. trimmerana K. (No. 57) = anglica 

 Alfk. The name spinigera may well be used for its extraordinarily 

 dimorphic spring form, thus named by Kirby. As to trimmerana 

 Auct. nee K., I do not know what synonymic names may be available 

 for use. It would certainly be unfortunate should some varietal name, 

 such as var. srotica, have to be used for the typical form.
