424 Rev. F. D. Morice and J. H. Durrant on the 



Type 2 : Melecta histrio F. (Ltr. 1810). 

 Crocisa Ltr. Cons-Gen. Crust-Ins. 338, 439 no. 532 (1810)— 

 [Type : histriO F. — this was not an original type, but is congeneric 

 with histrionica Illig., the Type as shown above.] 



The names Crocisa Jrn. and Melecta Ltr. were originally 

 given to the same generic conception, but as they are now 

 restricted to different types it will be convenient to print 

 the history of Melecta for reference. 



Melecta Ltr. (1802)

The name Crocisa was first published in the Erlangen 

 List. Of the three specific names included under it, two 

 {punctata and armata) are synonyms and denote the species 

 described by Fabricius (1775) as Ajpis 'punctata {— Melecta 

 armata Pzr., of Dalla Torre's Catalogue). The third name 

 " Nomada scatellata " (sic) is evidently intended for the 

 " Nomada scutellaris Fab." figured by Panzer (Fn. Ins. 

 Germ. 32-7) as shown by Jurine (Nouv. Meth. Hym. 241). 



Illiger (1806) recognised that the scutellaris of Panzer 

 was not the true scutellaris of Fabricius, and renamed 

 Panzer's species histrionica Illiger. 



The genus Crocisa then was founded on two species, viz. 

 punctata F. and histrionica Illig., one of which must be 

 its Type. 



In 1802 Latreille published his genus Melecta for punctata 

 F., with which he associated histrio F. and scutellaris F. 

 (HN. Fourmis etc.). Later in the same year he again used 

 Melecta to include punctata and histrio but omitted scutel- 

 laris, and in 1803 he cited punctata F. as the Type of 

 Melecta Ltr. 



In 1809-10 Latreille definitely broke up the genus 

 which he had formerly called Melecta into two genera, viz. 

 Melecta Ltr. and Crocisa Jrn,, distinguishing them on the 

 same characters by which we still separate them (viz.
