name of "Robin's Pincushions;" they are easily bred by placing 

 the galls under a tumbler, and are beautiful objects for the mi- 

 croscope, for in elegance of form and beauty of colouring they 

 can scarcely be surpassed. These mossy excrescences are sup- 

 posed to be entirely formed hy Cy^iips Rosa, and our insects 

 are said to feed on their larva^, and most skilful parasites they 

 must be, for in breeding them 1 have often obtained nothing 

 but the Callimome, and it is very remarkable that from mul- 

 titudes of the galls of the Wild Carrot I never bred any other 

 insect than the C. Dauci. 



In the Stockholm Transactions for 1820, and a subsequent 

 vol., a synoptic table and descriptions of the species will be 

 found; in the 1st vol. of the Ent. Trans. Mr. Walker has de- 

 scribed 61 species, and 18 were recorded in the Guide. 



3*. subterraneus Curt. B. E.pl. 552. ? . 



Minutely sliagreened ; deep blue, head and thorax with rather large 

 but shallow punctures, the latter variegated with violet ; antennae 

 black, basal joint ferruginous, except at the tip ; mouth and abdomen 

 ferruginous-ochre ; back black with a cupreous or violet tinge, except- 

 ing a band near the base, apex green ; ovipositor ferruginous, sheaths 

 pubescent and black above, tips whitish ; superior wings with a pale 

 yellow brown oval sjiace on the disc ; nervures piceous : legs and tips 

 of coxae, excepting the posterior, ferruginous-ochre; hinder tibiae 

 piceous, ferruginous towards the apex ; tarsi ochreous, tips piceous. 

 Male smaller, antennaj entirely black, and the abdomen without an 

 ochreous band near the base. 

 Bred by Mr. E. A. Johnson from galls of the Beech-tree, 

 formed by the larvae of Cynips aptera, on which they are pa- 

 rasitic. 



5. Geranii Curt. ? li line long, ovipositor l^ line; beautiful green, 

 head rather cupreous ; antennae black, basal joint, excepting the tip, 

 ochreous : abdomen with an ochreous band near the base, legs of the 

 same colour, hinder coxjk green, ochreous at the tips and their tibiae 

 brownish towards the base : nervures yellowish bi-own. 

 Bred from the gall of a native Geranium. — J. C. 



1 2. Arundinis Curt. ? Length ll, ovipositor l §- : bright shining green ; 

 head aureous or cupreous, antennae black, basal joint beneath ochreous, 

 with a spot of the same near the base of the abdomen : legs yellow- 

 ochre, coxae green outside, faint in the anterior pair, base of tarsi 

 whitish-ochre, tips brownish ; nervures ochreous. 

 Middle of August on rushes, Blackgang Chine. — J. C. 



15. \Ja,\XCiCurt, 9 1+ line, ovipositor 5 ; green, antenna? black, basal 

 joint straw colour beneath : legs whitish-ochre, thighs, excepting the 

 tips, green, hinder tibiae violaceous-black, except at the base and tips, 

 apex of tarsi blackish, especially the posterior. 

 I observed, the middle of August, at the back of the Isle of 

 Wight, vast numbers of the umbels oi DaucusCarota producing 

 galls; they contained bright orange- coloured larvse, from which 

 I bred a great number of this insect of both sexes the follow- 

 ing September. 



The Plant is Rosa spinoaissima (Burnet Rose).
