in 17 Osmia-species of the adunca- Group. 1G7 



his description is quoted in full by Schmiedeknecht. But 

 it can hardly be the morawitzii of Ducke ; and I have 

 reason to think that the true morawitzi, Gerst. (= loti 

 Moraw.) is yet another species. 



See on these points the note appended at the end of 

 this paper, and my figures of the antennae (<J) in the 

 species there discussed. The latter I have drawn each 

 in several points of view (1) from in front — the 'widest 

 aspect ; (2) from above — the narroivest ; (3) from behind — 

 to display as fully as possible the convexities of the 

 separate joints. The present species is represented in 

 Figs. 24, etc.* 



This insect — moraioitzi, Perez, as I shall call it for the 

 present — I have taken freely in Algeria and occasionally 

 in South France (never further east !). It frequents 

 Echium, which loti (teste, Morawitz) does not. 



To the characters given by Perez the following may 

 be added. 



Intermediate and hind femora in both sexes acutely 

 spined at their apices (Fig. 19). The character is unusual, 

 and striking (when not concealed by the tibia). <J Hind 

 metatarsus unusually elongate, measuring quite 4 of the 

 tibia (in adunca less than -f). ^ Last ventral segment 

 produced at the apex as in adunca, but into a narrower 

 spine, rather linear than triangular, and not (as in adunca) 

 red but black. (I must own that I cannot follow Perez 

 in his description of the last dorsal segment which seems 

 to me less and not more impressed transversely than that 

 of adunca.) 



The calcaria vary strangely in colour. They may be 

 quite pale or almost as black as in adunca ! 



Fig. 5. Apices of the main lobes sharply angular, but 

 a little deflexed which gives them a truncate look, their 

 slightly convex margins run rather obliquely. 



The process has a distinctly constricted petiole-like base; 

 at the apex it is divided by a triangular incision into two 

 slightly pilose reniform lobes which widen gradually from 

 apex to base. 



This is one of the " types " of Friese's pici taken by me 

 in Syria, and described by him in Ent. Nachricht. As 



* Although I have taken extreme care in placing the antenna} as 

 horizontally as possible, some joints are inevitably foreshortened 

 differently in different aspects. So their comparative lengths cannot 

 be reckoned with precision from these figures.
