and laughed when they saw our mouths full of dry dust. It is 

 about the shape and size of a small fig, of a dark reddish 

 purple colour, with rows of small thorns at the upper end. 

 The interior was filled with a snutf-coloured, spongy substance, 

 crumbling into dust when crushed. Those less mature were 

 green, and spongy within, and on the surface unctuous to the 

 touch. They wei'e generally perforated with a small round 

 hole. This fact, together with their containing no seeds, and 

 the mode of their attachment, indicate them to be the work of 

 an insect. The Arabs speak of another, yellowish excrescence 

 of the same tree, called Afs, which 1 believe to be merely an 

 immature stage of the same production." Some insects came 

 out of the apples on their way to England, and were found 

 among the cotton in which they were packed. Mr. Westwood 

 has figured and described a Hymenopterous insect, under the 

 name Pi7npla Sodomitica, which he supposes parasitical on 

 Cynips insana, the gall-making insect which produces these 

 apples. 



4t. Descriptions of several new Species of Exotic Hemipterous 

 Insects. By J. O. Westwood, F.L.S. &c. 



Family Pentatomid^. Eumetopia fssiceps, distinguished 

 by the head bearing two singularly curved porrected processes, 

 one before each eye, and also a square central process pro- 

 jected over the mouth ; altogether a very remarkable for- 

 mation ; it inhabits South America. Oncoscelis Aiistralasiw, 

 distinguished from Aspongopus De Laporte by the possession 

 of tarsal pulvilli, and the insertion of the antennae ; and from 

 Rhaphigaster, Edessa, &c. by the simple sternum and abdomen. 

 Cgclogaster pallidus, o? w,'\\ic\\ the simple sternum, rounded and 

 depressed form, and very short antennae and rostrum, distin- 

 guish it from Tesseratomas, Jpoiigopus, and others of the Scutati, 

 whose antennae have but four joints. Family Capsid^. Eu- 

 cerocoris nigriceps, remarkably distinguished from other Linnaean 

 Cimices by the extraordinary length of its slender antennae, 

 almost thrice as long as the body. Family Reduviid.e. Enico- 

 cej>halus basalis, fuhescens, tasmanicus, and favicollis. In 

 this remarkable genus the pro-, meso-, and metathorax are 

 perfectly separate from each other, transverse, and singularly 

 formed.
