NEW BRITISH SPECIES, ETC., IX 1872. 9 



Kraatzii, both species of Gymnusa, Lamprinus saginatus, 

 BoUtohlus incUuans and cingulatus, Staphylinus erythrop- 

 terus, Thhiobius linearis, Acidota crenata and cruentata (in 

 numbers, in moss), Scydmcenus nanus, Epurcoa variegata, 

 bnmunda, parvula, and angustula, Atomaria Hislopi, 

 Tetratoma Desmarestii and ancora, and Rhinoncus denti- 

 coliis, have all occurred (mostly in numbers), with very many 

 other species less noteworthy, near Scarborough. Mr. Law- 

 son has also, amongst a number of the rare Hydroporiis 

 ohsoletus, observed an individual with the right antenna 

 quadri-furcate (described in Ent. M. M. viii, p. 288). 



To this gentleman (apropos of whom I may be pardoned 

 for saying, that I wish the Darwinian hypothesis were indis- 

 putably true, and that its periods of development had been 

 so partially deranged, that he might, retaining his present 

 abilities, have been born an annelid, and not a mammal; for 

 then we could, without inconvenience to him, have cut him 

 into separate Lawsons, by whom, scattered judiciously over 

 Great Britain, our Coleopterous Fauna would be materially 

 increased), moreover, w^e are chiefly indebted for the great 

 impetus recently given to our knowledge of that most diffi- 

 cult group the AnisotomidcB, of Avhich the British list may 

 now fairly be said to exceed the usual average of species. 

 These insects, usually obtained (if at all) either singly or in 

 scanty numbers (and mostly in the form o? Anisotoma cal- 

 carata!) by persistent evening-sweeping in localities for 

 their occurrence in which the collector can assign no reason, 

 appear to band together by genera and species near Scar- 

 borough, for the express purpose of being caught by Mr. 

 Lawson; who on one occasion took during the past year in 

 flood refuse upwards of 300 examples ! The species that 

 have been there taken by him are Hydnobius punctatissi- 

 mits, piinctatiis (also taken by Mr. T. Wilkinson) and stri-
