This beautiful species is parasitic, in the larva state, upon 

 the larvae of Nematus Gallicola, Westw. Steph. ; the female 

 piercing the gall with her ovipositor, in order to lay her eggs 

 in the centre, where the young larva of the Nematus resides. 



Gynandromorphous* Hymenopterous Insects. — In the last 

 number of Mr. Curtis's 'British Entomology,' (June, 1838, pi. 

 632), is figured an interesting specimen of the common Ten- 

 thredo angulata, the right hand half of which is feminine, and 

 that on the left masculine, with this observation. — " Never 

 having seen any other hymenopterous insect of this kind, I 

 have been induced to figure the Tenthredo in the annexed 

 plate : and as the sexes vary in the colour and markings of 

 the abdomen &c. they are rendered conspicuous in the figure." 

 It is indeed only very recently that gynandromorphites have 

 been discovered in this order of insects, none being recorded in 

 Burmeister's ' Manual, 7 but there are now several on. record. 

 The Baron de Romand has figured a gynandromorphous spe- 

 cimen of Scolia 6-maculata, Fabr. ('Ann. Soc. Ent. de France, 7 



1835, pi. 4, C.) ; M. C. Wesmael has figured a double-sexed 

 Ichneumon, in which the anterior portion of the body is that 

 of Ich. extensorius female, and the posterior part of the body 

 that of Ich. luctatorius male, thus proving that these suppos- 

 ed species are but the sexes of one. ('Bull. Acad. Bruxell.' 



1836, No. 10). Mr. F. Smith captured a singular double-sex- 

 ed specimen of Anthophora retusa, of which he has commu- 

 nicated a drawing to the Entomological Society, and which 

 Mr. Shuckard has noticed in the 'Entomol. Magazine' for Ju- 

 ly, 1836; in which he also mentions a specimen of Cimbex 

 Griffinii, having the left anterior leg only, female; and a spe- 

 cimen of Andrena fulvescens, in which the sexual characters 

 are intimately intermingled. — J. O. Westw ood. 



Mr. Newman's Remarks on the Antennae of Inseets. — I 

 was amused, a few years ago, by observing the operations of 

 wood ants, {Formica rnfa), passing up the trunk of a fir tree 

 in considerable numbers. I kicked the tree, and instantly, as 

 if by enchantment, every vagrant ant suspended its opera- 

 tions, and fantastically leaned forward with the antennae por- 



* M. Lacordaire has proposed this term for monstrosities in which the sex- 

 es are unnaturally blended, retaining that of hermaphrodites for those which 

 are naturally double-sexed, as the Mollusca.
