This pretty species varies in tlio expansion of its wings from « to lOi- lines. It is blue-black, with a silvery lino 

 before the eyes ; the palpi black above, fulvous beneath. The thorax and breast unspotted ; the abdomen with 

 the fourth segment entirely fulvous ; the fifth with a few fulvous scales. The fan tail marked beneath and at the 

 sides with white hairs. The hind tibiro annulated in the middle, and at the tip with white. The fore wings 

 with a fulvous red patch at the tip. The veins, margins, and fasciai black. 



This is rather an uncommon siiecies, but has occurred occasionally near London. Mr. Vigors is stated to have 

 reared it from an apple-tree grovvn at Little Chelsea, and to have obtained it from Ireland, but I learn from 

 Mr. Child of Birmingham, that lie reared this sjiecies (of which I have a note) from willow. Iliibner also 

 describes the larva as subpubescent ; whitish, with the head and tail brownish, adding with a doubt that it 

 inhabits the branches of Salix alba ; so that perhaps Mr. Vigors' specimens, bred from an apple, were another of 

 the red-belted species. I took it on the 5th of July, 1827, on Umbelliferte in Battersea fields. Mr. Haworth 

 gives the beginning of August as its period.

Tliis species is at once distinguished by the palpi, which are fulvous beneath in both sexes, a character 

 expressly mentioned by Linnasus, which enables us to settle the very disputed sjTionymcs of various species to 

 which the name Culiciformis has been applied. The expan.sion of the wings varies from ten lines to an inch 

 (our figure 12 is therefore somewhat enlarged beyond the natural size). It is blue-black; the palpi are 

 fulvous beneath, a white line before, and a white spot behind the eyes ; the thorax unspotted above, but with 

 a fulvous spot on each side the breast ; the abdomen with the fourth segment entirely fulvous red ; the 

 fan-tail entirely black ; the wings liyaline, with the margins and transverse bar black, in certain situations 

 glossed with blue, the apex somewhat violet ; the cilia brown ; the legs blue-black ; the spurs yellowish, and 

 the tarsi dirty white. The male difl'ers in its smaller size and ciliated antennaj. The larva is dirty white, 

 subpubescent, with a brown head ; it feeds upon the wood of the plum and apple. The chrysalis is elongated 

 and brown. 



This species is also far from common. It has, however, been taken in the woods round London, at 

 Gravesend, and Dublin. Mr. Haworth did not discriminate it from the next species. 



* I adopt this form in preference to Formiciforme, because 1 believe it has the priority. If it be more classical (" Formica, not Formicus. being 

 the generic name ; whence the present trivial name is derived," as Mr. Newman informs us), t do not uuderstaud why the names Vespiformis 

 and Tipuliformis should be retained.
