three species given, two of which are new ; and reference is made 

 to the descriptions of three others, making in the whole six 

 species. 



Pacuylosticta, the first Hymenopterous genus noticed, is 

 new. It contains three species, (the males of which only are 

 known,) which at first sight closely resemble the Hylotoince. 

 Its characters are, " Antennae short, clavate, 5-jointed ; anterior 

 wings dilated at their apex, stigma semilunar; marginal cells 

 two ; submarginal three, the second of these penetrated by a 

 recurrent nerve: second, third, and fourth joints of the hinder 

 tarsi very short." All the specimens yet received are from 

 Brazil, to which country also the following genus, which is 

 closely allied to Pachylosticta is referable. It is worthy of re- 

 mark, that as of Pachylosticta males only are known, so of 

 Syzygonia none but females have hitherto been seen by Professor 

 Klug. Syzyggnia ; ^' Antennae short, clavate ; with four or 

 five joints before the club ; club solid : marginal cell solitary, 

 appendiculate ; submarginal, four.*' The species, which are two 

 in number, are related to the genus Abia of Dr. Leach. Of 

 Tarpa^ of which there were only two species previously known, 

 there are now described nine; of Cryptocerus^ ten, with re- 

 ference to three others, making in all thirteen ; and of Ceramiusy 

 four species.

In those portions of our previous numbers which are devoted 

 to the Proceedings of Learned Societies on subjects connected with 

 Zoology, such ample notices have been given relative to the papers 

 contained in the present volume of the Philosophical Transactions, 

 that, with one exception only, nothing remains to be done in our 

 analytical department, save the enumeration of the articles, ac- 

 companied by a reference to those of our pages in which their more 

 prominent facts have been already embodied.
