West wood's Classification of Insects. 6*27 



** Metathorax unarmed. 



Myr. dorrtestica, Shuck. 



Dilute ferruginea, abdomine apice fusco. 



Length, Fern. 2 lines. Neut. f line. 



Pale ferruginous, opaque, the abdomen shining, emarginate in front 

 for the reception of the nodose peduncle, with the margin of the first, 

 and the whole of the remaining segments, dark fuscous. 



The male of this species I am also unacquainted with. Dr. Bos- 

 tock's paper before alluded to gives a full account of his endeavours to 

 eradicate this domestic intruder. 



Myr. terminalis, Shuck. 



Dilute ferruginea, nitida, capite et abdomine nigro. 

 Neut. length 1 line. 



Pale ferruginous, shining, the head and the abdomen black, the lat- 

 ter not emarginate in front for the reception of the nodose peduncle, 

 but lanceolate. 



I am unacquainted with both male and female of this species, which 

 was found by my friend A. Ingpen, Esq. in a hot-house in Chelsea. — 

 It forms a remarkable exception to the rest in the genus, from its lan- 

 ceolate abdomen, which is not emarginate in front. I possess other 

 minute species of this genus from various parts of the world, which I 

 will take another opportunity of describing, not having leisure at the 

 present moment.

Art. I. — Introduction to the Modern Classification of Insects; 

 founded on their Natural Habits and corresponding Organization: 

 with Observations on the Economy and Transformations of the 

 different Families. To which is added a descriptive Synopsis of 

 all the British Genera, and Notices of the more remarkable Fo- 

 reign Genera. By J. O. Westwood, F.L.S., Secretary to the 

 Entomological Society, of London, &c. &c. London : Longman 

 and Co. Parts 1 to 6. To be completed in about ten monthly 

 parts, with about 130 Engravings in wood, each containing nume- 

 rous figures, and one coloured Plate illustrative of the Orders. 



Perhaps the chief characteristic of the modern classification 

 of every branch of zoological science, is founded upon the in- 

 vestigation of the natural relations existing between the va- 

 rious groups of species. In the Linnamn arrangement, al- 

 though we may find the name of a species if known to the great
