already exist a quantity of materials, only awaiting a skilful 

 hand to put them together. If well executed, and published 

 at a moderate price, we have no doubt it would secure an 

 extensive sale, and become the indispensable manual of every 

 Lepidopterologist. 



7. Monograpkie des Braconides de Belpique (suite), par C 

 Wesmael. 4to. Bnixelles, 1837. — The third group of the 

 '' Braconides Endodontes" namely, the ^' Areolaires" ^axQ here 

 described. It contains the genera Microdiis, Ischius, Agathis, 

 Microgaster, and Adelins. There consequently still remains 

 the group of " Cyclostome" and all the " Bracones Exodontes" 

 to complete the division : we therefore fear that, if M. Wesmael 

 does not progress more rapidly, many of his names will be 

 anticipated, and his labours consequently rendered vain. Mere 

 priority of possession of the field ought not to secure the exclu- 

 sive appropriation of its produce, unless it be diligently and 

 uninterruptedly cultivated. We are constrained to this remark, 

 from his having completed only one small group since the 

 commencement of his work, which was published two years 

 ago ; and in the Preface to which he remarks angrily upon 

 Nees von Essenbeck, for having re-published, with additions, 

 his own scattered papers upon the group, in the interval 

 between the reading and publication of M. Wesmael's " Mo- 

 nographie," whereby many of the names of the latter were 

 superseded. This, at best, is frivolous ; for what is there in a 

 name, at least, the name that can be acquired from the descrip- 

 tion of a few species ? The proficient derives more satisfaction 

 from extensive views and profound knowledge, than it is 

 possible to concede to the idle gratification of seeing one's 

 mutilated name tacked behind the barbarous one of an insect; 

 although we willingly admit that the correct description of 

 new species implies extensive knowledge, that confused syno- 

 nyms may be avoided, as well as judgment, to give as much 

 and no more than may be absolutely necessary.
