APIS, (**, c. 2. V.) 257 



Maris Corpus cinereo-villosulum. Antennae fili- 

 formeSj capite longiores(^). Fades ante an- 

 tennas niveo-villosiila. Abdomen inflexum ano 

 acute bidentato(/). Venter segmento secundo 

 tuberculo elevatiusculo munito(ra), cui ex 

 adverse opponitur apud anum cavitas rotunda^ 

 tomentoso-paliida . 

 This little Apis, by far the most minute species 

 of this genus, that I have yet seen, is common^ 

 during the summer and autumnal months, in the 

 blossoms of Campanula Trachelium, rotundifolia, 

 and hyhrida, and, what deserves to be remarked, 

 I never found it in the flowers of any other genus 

 of plants. The males are often taken asleep in 

 these flowers, their abdomen is then doubled, so 

 that the tubercle, with which its base is armedj 

 fits into the cavity near the anus. The aculeates 

 partake of the habit of A. maxillosa, and the 

 males in the same degree resemble A.Jlorisomnis, 

 a further proof of the identity of those insects. 

 I have never met with this insect in any other 

 situation than the above, and therefore I can say 

 nothing further with respect to their mode of 

 nidification, than that it is most probable that, with 

 the other species of this subdivision, they make 

 their cells in posts, rails, and the like. The male 

 of A. campanularum is, I think beyond a doubtj 

 the A.Jlorisomnis minima of Christius.
