former with three fovea? on the crown, one close to the base ; the latter with the 

 anterior margins and the posterior angles membranous and transparent ; a 

 deep channel between two long fovea? on the back, and a large depression on 

 each of the angles. Elytra not striated, but covered with large deep punc- 

 tures, appearing rather regular under a weak lens, but scattered under a high 

 power ; legs ferruginous, the tarsi piceous at their tips." — Curtis. I. c.

 p. 100—109. (published in 1806), while it tends to show the opinions of those 

 writers upon the evident affinity between the various members of this group, 

 as quoted in the synonyms to my Catalogue, will at the same time exemplify 

 the originality of Sturm's arrangement, published in 1807, and the historical 

 correctness of those who, in order to oppugn particular views, care not how far 

 they mislead their readers. Sturm's arrangement in this, as in other places, 

 being merely a copy of that of the Systema Eieutheratorum, with the adoption 

 of some few genera, proposed subsequently to the publication of that work. 



Page 159. Phalacrus maritimus. Upon a re-examination of this insect I have 

 my doubts whether it be placed in its proper location ; as in many points it 

 approximates to the Byrrhidse, though in others it departs therefrom.

*** I have recently obtained several evidently distinct species of Hydraena, 

 Hydrobius, &c, ; as well as of Hydradephaga and Bembidiidae, which, from 

 want of time, it is impossible for me to introduce into the present Appendix.
