1 . H. Campamilarum Khb. Mon. jo/. 16./ 14 & 1 5. 9 & c? • 

 SliiiHn<^, thickly and minutely punctured, and sparingly 

 clothed with minute ochreous pubescence; the face and espe- 

 cially the clypeus producing long ochreous hairs in the male, 

 and the margin and underside ot" the abdomen in that sex, ex- 

 cept at the base, are thinly covered with yellowish hairs, but in 

 the female they are long and thick; wings fuscous round the 

 margins, the nervuresand stigma piceous; spurs ochreous, the 

 basal joint of tarsi producing long whitish hairs in the female, 

 especially the intermediate, inside of the same joint in the pos- 

 terior clothed with bright ferruginous hairs ; claws subfer- 

 ruginous. 



" This little Apis," (says Mr. Kirb}^,) "by far the most mi- 

 nute species of this genus that I have yet seen, is common, 

 durino; 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 tliat the tu- 

 bercle, with which its base is armed, fits into the cavitv near 

 the anus." On the 29th of June I once found it in abundance 

 in a garden at Fulham. 

 2. 11. truncorum Linn. — P«?iz.64'.15. — Curt.B.E.pl. 504 ? . 



Female slate-black, slightly pubescent with whitish hairs, 

 and closely covered with strong punctures, especially the head 

 and thorax, a spot of long white hairs on each side the clypeus, 

 sides of thorax similarly clothed. Abdomen concave at the 

 base, with a transverse ridge and another at the base of the 2nd 

 segment, the anterior margin of the 1st clothed at the sides 

 with white pubescence, sometimes extending across, the 3 fol- 

 lowing segments ciliated with white hairs, forming very narrow 

 bands, the pubescence at the apex very short and ochreous, the 

 pubescence beneath as well as on the basal joint of the hinder 

 tarsi ferruginous ochre: wings tinged with brown, especially 

 across the middle; nervures and stigma piceous, spurs ochre- 

 ous, tips of tarsi and claws ferruginous. " Male smaller: cheeks 

 unarmed : maxillae not carinated above : abdomen with the 

 margins of the anterior segments whitish: anus inflexed, last 

 segment entire, somewhat compressed with a little transverse 

 fovea on each side: belly with white hairs at the base, convex, 

 with a tolerably deep cavity at the apex." — Kirhy. 



As I have never seen the male, the above description is 

 translated from Mr. Kirby's Monograph : the female very 

 much resembles the same sex of Osmia leiicomelana, but is 

 rather more slender; the head is proportionably larger; it is 

 more strongly punctured, and the hollow space above at the 

 base of the 1st abdominal segment at once distinguishes it. 



Taken at Brentford : 1 believe my female came iVom Norfolk. 



The Plant is Campanula (Prismatocarpus LI Her ) hylrida. 

 Corn Bell-flower.
