02 NOTICE OF 



The generic name, Xylota, we could have wished restricted to 

 the species i^lp'iens, which appears to us typical; and a new 

 name might have been given to the remaining species. The 

 Xijlotce have a remarkable analogical resemblance to the 

 Ichnetiutones, running with great activity about the leaves 

 and stems of plants, in the sunshine, with their wings closely 

 folded on their backs. — No. 107 contains, 1. The very com- 

 mon Cijclirus rostratus, so remarkable for its hissing noise, 

 very much resembling that made by a water-beetle, Padobius 

 Hermanni: this noise has often attracted our attention when 

 we have captured it. The Cychri usually conceal themselves 

 at the roots of long grass, or under stones, in the day-time ; 

 and in the night, or sometimes in moist showery weather, even 

 in the day, they ascend shrubs, in search of larvae and perfect 

 insects, on which, like the Calosomce, they feed. 2. Pliagonia 

 smaragdina. This is a beautiful and interesting little Hymenop- 

 terous parasite. The genus appears identical with Pachylar- 

 thrtis (Westvv.) characterized in the Philosophical Magazine for 

 August, 1832; and, much as we deprecate the publication of 

 the characters of disconnected genera, for the paltry fame of 

 attaching a name to them, it is our duty, and it ever shall be 

 our endeavour, to give precedence to priority, however obtained, 

 as it seems our only sound mode of deciding nomenclature: 

 one species, that named Insigjiis by Mr. Westwood, seems to 

 have been described by Dalman in the Stockholm Transactions, 

 under the name Diplolep'is patellana. Mr. Curtis has made 

 a mistake in referring this little insect to the family Cynip'idcc, 

 to which it has no affinity. 3. Nola monachcdh, a pretty 

 little moth, and elegantly figured. Mr. Curtis wishes to 

 make this genus something like a stepping-stone from the 

 Pyralides to the Torticides ; we do not see the weight of 

 his arguments on this subject. 4. Helophilus Ruddil. This 

 is a beautiful and interesting plate : the fly was taken by 

 L. Rudd, Esq. near Yarmouth, in Norfolk : it has the head 

 and antennae of a Criorhina, and the abdomen of a Tahanus ; 

 the thorax is longitudinally striped, like that of Helophilus, to 

 which genus, however, it does not appear to us to be at all 

 nearly related. — No. 108 contains, 1. Hypoplceus hicolor. 

 2. Trachea atri2)licis, with a larva copied from Hubner, in 

 which we fear there is some mistake, as Roesel (see Mr. Curtis's 

 text), Fabricius, Haworth, Stephens, &c. agree in describing it
