" Dactylopius. In. other -words, I doubt the parasitism of 

 " Telenomua upon Dactylopius. The Encyrtus, however, is 

 " without much doubt properly considered a parasite of the 

 " coccid." 



Mr. Howard is undoubtedly right, but it is hard to tell 

 who really was the host of this parasite as these masses of 

 Dactylopius present quite a little insect fauna of their own, 

 which I hope on some future occasion to give a list of. In 

 conclusion I desire to thank Messrs. Howard, Cockerell and 

 Ashmead for their kindness in helping me. 



NOTES ON THE ECONOMIC USES OF THE 

 COMPOSITE. 



Part II. 



THE following is the conclusion of 

 article begun in last number. 



Mr. Ewen's excellent 



Jerusalem artichoke. H. Tuberosus. 



This plant is said to attain the fullest perfection in Brazil. 

 Its tubers are excellent vegetables, and are the basis of the well 

 known Palestine soup. The stems are said to afford much 

 valuable textile fibre. The plant requires a soil rich in Potash. 

 The root contains Inuline (a sort of starch) and uncrystalizable 

 sugar. 



Safflower. Carthamus Tinctorius. Carthame (fr.) 



Is cultivated for its Petals and oil-.seed in France, Spain, 

 Italy, Egypt, China and India. The coloring matter (Carthamic 

 acid)(Cl4. H.16. 014.) is extracted from the petals of the flowers. 

 It is used as a red, rose and plush tint dye for silks and satins. 

 Safflower extract, dried and mixed with ground tale forms the 

 popular cosmetic called Rouge. The seeds yield about 20 per 

 cent of fatty oil, called "Curdie'' oil. There are two ways of 

 extracting it. (a) The clean seeds are crushed and pressed, pro- 

 ducing about 25 per cent, of lighl colored oil of good burning 

 qualities. (I>.) The natives in India prepare a black tarry oil from 

 tin' seed by a rude sort of destructive distillation per tl<±,,, sum. 

 It is useless for burning but is highly esteemed by them for 

 dressing and preserving leather vessels exposed to water, such as 

 the " Masaks ' of the water-carriers,
