1473. T. corymbostim Sch. Bip. (= Chrysanthemum corymbosum Z., and 

 Pyrethrum corymbosum Scop.). Kerner made comparative cultivations of this 

 species in the Vienna Botanic Garden and on the Blaser in the Tyrol, and observed 

 that the lowland specimens developed larger heads (26 mm. in diameter), and larger 

 ray-florets (tongues 8 mm. long and 4 mm. broad) than the highland ones, the heads 

 of which were only 20 mm. in diameter with ray-florets 7 mm. long. 



Visitors. Herm. Muller observed the following in Thuringia. 



A. Coleoptera. (a) Buprestidae -. 1. Anthaxia nitidula L. (6) Cerambycidae: 

 2. Strangalia bifasciata Mull. 5 and J, freq. ; 3. S. melanura L., both po-dvg.

 aculeata L. (e) Oedemeridae : 6. Oedemera marginata F. ; 7. O. virescens Z., 

 po-dvg. (f) Telephoridae : 8. Danacea pallipes Pz. ; 9. Dasytes fiavipes F. 



B. Diptera. (a) Bombyliidae: 10. Anthrax morio Z. (b) Empidae: 11. Empis 

 livida Z., freq., skg. (c) Muscidaei 12. Aricia sp. ; 13. Ulidia erythrophthalma Mg., 

 in very large numbers. (d) Straliomyidae : 14. Nemotelus pantherinus Z., skg.

 ptera. (a) Apidae: 17. Halictus maculatus Sm. $, freq., skg. and po-cltg. ; 

 18. Prosopis confusa Nyl. 5; 19. P. variegata F. $ and $, skg. and po-dvg., 

 also in copuld on the heads. (l>) Sphegidae: 20. Cerceris variabilis Schr. 5.

 cephalotes F., skg. (?). E. Lepidoptera. (a) Rhopalocera : 23. Melitaea athalia 

 Fsp., skg. ; 24. Thecla spini 6". V., do. (b) Sphingidae : 25. Zygaena sp., do. 



Loew noticed the Sphegid Dinetus pictus F. t in the Berlin Botanic Garden. 



1474. T. Parthenium Sch. Bip. ( = Chrysanthemum Parthenium Bernh, 

 Matricaria Parthenia Z., and Pyrethrum Parthenium Sm.). (Knuth, ' BL u. Insekt. 

 a. d. nordfr. Ins.,' pp. 93, 159.) In this species the style of the white female ray- 

 florets has no apical sweeping-hairs, but the yellow disk-florets possess them just lil 

 Matricaria Chamomilla, though the stylar branches do not diverge so much in 

 second stage of anthesis (cf. Fig. 202, 9). As Kirchner remarks (' Flora 

 Stuttgart,' p. 711), they do not project at all from the corolla after the anthi 

 cylinder has become retracted. 



The following were recorded by the observers, and for the localities stated, 



Herm. Mailer (H. M.) and Buddeberg (Budd.), (Herm. Muller, Fertilisatioi 

 P- 33i ' Weit. Beob.,' Ill, p. 96) the bee Halictus smeathmanellus K. $, skg. (H. 

 Budd.), an Evaniid (Foenus sp.), skg. (H. M., Budd.), and the Sphingid Sesia tipuli- 

 formis CI., skg. (H. M.). Schletterer (Pola), 3 bees (1. Halictus levigatus K. J 

 2. H. patellatus Mor. ; 3. Andrena carbonaria Z.). 



1475. T. alpinum Sch. Bip. (= Chrysanthemum alpinum Z.). (Herm. Miiller, 

 ' Alpenblumen,' pp. 430-2.) This species is gynomonoecious with protandrous 

 hermaphrodite florets. The yellow disk-florets greatly exceed 100 in number, anc 

 cover a circular area 10 mm. in diameter, which is extended by the white ray-floret 

 (about 30 in number) to 30-4 mm. The florets develop in centripetal order. Tr 

 possibility of self-pollination is ensured. 



Visitors. Herm. Muller observed 3 beetles, 35 flies, 4 Hymenoptera, anc 

 4 Lepidoptera. 



Loew saw a Muscid (Anthomyia sp.) on the Piz Umbrail (' Bliitenbiol. Floristik.' 

 P- 397)-
