146 Analyses of Boohs. 



and proposes to consider the uniflorous ones as belonging to Lotus 

 of which they would form a separate section, which, with reference 

 to the size of the flowers, might be called 3Iicrolotus. The two 

 genera would then be characterized by the form of the flower ; and 

 the peculiarities observable in the organs of vegetation would again 

 be reduced to their proper level, that of subsidiary, not essential cha- 

 racters. In the true Hosackiae the claw of the vexillura is always 

 at some distance from those of the other petals ; the alae adhere by 

 their margins to the carina, and usually (if not always) spread at 

 right angles from it ; the carina is usually less rostrate than in Lotus 

 and the stigma more distinctly capitate. In Microlotus the flower 

 does not present any essential differences from that of our European 

 Lotl. The author describes 11 species of Hosackia, and 5 species of 

 Microlotus. 



ENTOMOLOGY. 



Descriptions, ^'c, of the Insects collected by Captain P. 

 P. King, R. N., F. ' R. S., iii the Survey of the Straits of 

 Magellan. By John Curtis, Esq., F. L. S. * A. H. Haliday, 

 Esq., M. A., and Francis Walker, Esq., F. L. S. 



The collection was formed along the coast from St. Paul's in Brazil 

 to Valparaiso. It is interesting to trace the similarity which exists 

 between the corresponding parallels of the southern and northern 

 hemispheres such as is afltbrded by the present collection. Thus the 

 genus Carabus appears unknown in S. America, excepting about lat. 

 50° where a species of that group with a narrow thorax has been 

 found ; the genus culex also occurs. The insects of S. America 

 bear little resemblance to those of S. Africa. Descriptions are 



fiven of species belonging to 66 genera of Hymenoptera, and of 

 8 genera of Diptera. 



Characters of Emhia, a genus of insects allied to the White 

 Ants J (Termites) with descriptions of the species of which it is 

 composed By J. O. West wood, Esq., F. L. S. 



This genus is remarkable at present not only because it consists of 

 species nearly allied to the white ants, but because it is composed of 

 3 exotic species, each from a difi^erent quarter of the globe, while a 

 single specimen only of each has hitherto come under the observation 

 of entomologists ; each possesses also characters of a higher rank than 

 mere specific distinction, whence he has been under the necessity of 

 considering each as a distinct subgenus ; these are Embia Savignii, 

 Oligotoma Saundersii, and Olynthia Braziliensis. Mr. Westwood 

 has also observed two species imbedded in Gum Copal or Anime, 

 which he has not been able sufficiently to identify. 



On a new Arachnide uniting the genera Gonyleptes and Pha- 

 langium. By the Rev. F. W. Hope, M.A., F.R.S., F.L.S. 



This remarkable insect with disproportionally long hinder legs, so 

 long that it is difficult to conceive of what utility they can be, was 

 collected in Brazil by the late Mr. Haworth, a zealous promoter of
