add that the (?)frontal in pi. 4. figs. G, 7, 8 is not a frontal., hut 

 a hone from the hase of the skull — seemingly the vomer. 

 PI. 4. figs. 1, 2, 3, called "a long bone of the wing/' is the 

 distal end of a humerus. PI. 4, figs. 4 & 5, is certainly not a 

 " wing-metacarpal," and is unlike any bone I know. 



In the third monograph (p. 0) the basi- occipital is described 

 and figured upside down, the outside of the skull being regarded 

 as the neural surface. But the only other error of determination 

 is that the bone regarded as a middle caudal of a Pterodactyle 

 (pi. 2. figs. 15, 1G) is no part of a Pterodactyle.

Longicornia Malayana ; or, a Descriptive Catalogue of the Species of 

 the three Longicorn Families Lamiidse, Cerambycidee, and Prio- 

 nidee collected bg Mr. A. R. Wallace in the Malay Archipelago. 

 By Francis P. Pascoe, F.L.S., Pres. Ent. Soc. Lond. (Part 1.) 

 Mr. Pascoe, the President of the Entomological Society of London, 

 having obtained the large collection of Longicorn Beetles formed by 

 Mr. Wallace during his travels in the Eastern Archipelago, has 

 undertaken the task of preparing a complete descriptive catalogue of 

 these interesting insects. Some conception of the magnitude of the 

 undertaking may be formed from the fact that Mr. Pascoe estimates 

 the total number of species in the collection at " something less than 

 a thousand," and of these more than eight hundred are believed to 

 be still undescribed. With such an important contribution to ento- 

 mological literature in their hands, the authorities of the Society 

 have wisely determined to devote a whole volume of their ' Transac- 

 tions to its reception ; and we have before us the first part of this 

 volume, the third of their third scries of ' Transactions.' We may 

 add that it is illustrated with four beautiful plates, the cost of which, 

 as Mr. Pascoe informs us, is partly defrayed by Mr. W. Wilson 

 Saunders. 



With regard to the classification of the Longicornia, Mr. Pascoe 

 seems to be rather dissatisfied with the complicated groupings in 

 vogue with many entomologists, and he reverts to the simpler system 

 of Leconte, in which the whole tribe or " suborder " is divided into 

 the three families, Lamiidce, Cerambgcidce, and Prionidce. As sub- 

 ordinate to these he admits a great number of subfamilies ; but he 

 holds that, for all practical purposes, these named divisions are 

 sufficient, and that any other sections that may be found necessary 

 should be indicated simply by numbers. 



The general inspection of the collection of Malayan Longicorns 

 leads Mr. Pascoe to dissent from the somewhat sweeping assertion 

 of Mr. Wallace, that, with respect to every branch of zoology, the 

 western islands of the Malayan archipelago belong to the Indian, 

 and the eastern to the Australian region. He gives a table of ten 

 of the largest genera in Mr. Wallace's collection, including 517
