PRACTICAL HINTS. 241 



13. — Collect the seed-heads of wild carrot, in September, for larvae 

 of Seinasia rujillana. 



14. — The larva of Scricoris euphorhiana is to be found in August 

 and September, feeding in the shoots of sea spurge (Euphorbia par alias), 

 which are drawn together. 



15. — In September, the dirty white larva of Penthina jtostremana 

 is to be found within the stems of Impatiens noli-me-tanf/erc. 



16. — The first week in October is the time to collect the full- 

 grown larvfe of Avf/i/rolepia maritimana. At that time they are to be 

 found mining in the roots of Eryngium maritimnm, sometimes to a 

 depth of six or eight inches below the surface of the sand. The long 

 pipe-like roots, for about three inches of sound root beyond the mine, 

 must be taken out very carefully, and the mined roots should not be 

 opened, but buried upright in sand. 



17. — The larvffi of Spilodt's palealis feed in the umbels of wild 

 carrot in September, drawing the umbels together with a web. 



18. — The larvfe of (iderliia animinatella are to be found in October, 

 mining the leaves of thistles. 



19. — The larvae of fieleclda scriptella are to be found in September, 

 in maple leaves. 



20. — The best time for collecting the larva> of Coleophora 

 fuscocuprella is in September and the beginning of October. It 

 feeds on nut, and may be found underneath the little leaves at the 

 termination of a bough. 



21. — At the end of September, the mined leaves of dogwood 

 contain full-fed larvae of Antispila trciUchkieUa. The mined leaves 

 should be placed on fine earth in a flower pot, covered with a glass 

 cylinder. As the larvae cut out their cases, remove the leaves. 



22. — The larvae of Caradrina morpJieus are to be found commonly 

 in October, on various low plants — wild hop, Chenopodiuin, etc., and in 

 the garden on horseradish, etc. 



23.— In October, the imagines of Calamia lutosa are to be found 

 by searching the reeds after dusk with a lantern. The species has 

 often been found to be abundant when searched for in localities where its 

 presence was not before suspected.

Die Schmetterlings-fauna von Hildesheiji. — Erster Theil : Tag- 

 falter, by A. R. Grote, M. A. [Published by the Roemer Museum, Hildes-

 Roemer-Muscums, Feb., 1897, the first part of a " Fauna of Hildesheim," 

 in which the butterflies are enumerated, and the results of an original 

 study in the neuration is given. The author endeavours to show the 

 manner in which the evolution of the wings has progressed. He 

 claims a diphyletic origin for the butterflies, and gives, on p. 29, a 

 genealogical tree, in which the Prtr»<7^■.s■i-Prty)^^io^i<y/rt(' are classed together 

 under the rubric a : " Vein ix of the primaries present, viii want- 

 ing," whilst all the other butterflies are embraced under: " b. Vein 

 viii present as a true vein, or a scar, or finally disappears, vein ix 

 wanting." In distinguishing the features of the neuration, the author 

 asserts that " the diminution of the radial veins is a character of
