XXX. A List of the Genera and Species belonging to the 

 JFamilg Cry ptocevidds, with Descriptions of new Species; 

 also a List of the Species of the Genus Echinopla. By 

 Frederick Smith, Esq., Pres. Entom. Soc. 



[Read 4th August, 1862.] 



This paper contains a complete list of the species belonging to the 

 various genera composing the family Cryptocer'idce ; reference is 

 made to every work in which figures of the species have appeared. 

 In order to render the list as complete as possible, figures of new 

 species, and also of such as have not been previously published, 

 are now given ; the new species are also described. Some of the 

 insects included in the genera Meranoplus, Cataulacus, and also in 

 Echinopla, have been described from unique examples, not in my 

 own collection, and therefore not available for such minute exa- 

 mination as others of which several specimens have been obtained ; 

 probably hereafter, when the species occur more plentifully, and 

 more thorough investigations are made, it may then be found ne- 

 cessary to separate some from the genera in which I have placed 

 them. Should any case of this kind occur, I beg those Ento- 

 mologists, who make such discoveries, to bear in mind, that the 

 circumstance is solely attributable to the fact of their being more 

 fortunate than myself in having at their command more ample 

 materials, which enables them to pursue their investigations 

 further than I could possibly do, possessing only unique speci- 

 mens, frequently the property of public museums or of private 

 individuals. I feel called upon to make these observations in con- 

 sequence of some revisions having appeared of certain species of 

 Formicidce , described by myself, by a continental author who has 

 overlooked this circumstance, and whose remarks convey the 

 impression of my having disregarded standard authorities from 

 a love of change, and fallen into error through carelessness of 

 investigation. In 1853 I produced a Monograph of the Cryp- 

 toceridce, which was published in the Transactions of this So- 

 ciety ; since that time many new species have been discovered, 

 and it has appeared to myself desirable that a new and complete 

 list should be drawn up and published ; such a list I have care- 

 fully prepared, and I hope it will prove as useful as I have endea- 

 voured to make it.
