Moles'=nest Beetles in the Harrow District. 



By HEEEWAED C. DOLLMAN, F.E.S. 



The difficulties of " moleing " in the meadowland of Perivale, 

 Sudbury, and Harrow, does not by any means arise from the paucity 

 of nest-hills ; rather, indeed, from perplexity as to where to start 

 one's operations, so numerous are nest-mounds, sometimes from five 

 to seven in one field. The nests do not apparently contain a great 

 number of forms ; this is to a great degree compensated for by some of 

 them occurring in considerable numbers. 



Aleochara spadicea, Er. — This species is certainly rare, perhaps 

 not more than four or five have been met with. 



Aleochara succicola, Th. — This species is decidedly scarce. 



Oxypoda spectabilis, Mark. — I was most delighted to secure a 

 specimen of this fine beetle from a very dark " leat'-nest." 1 believe 

 this constitutes the first record for 0. s/n't'tabilis as a "mole " species. 



Oxypoda longipes, Muls. — This is, with the exception of the 

 Heterathrops, quite the most abundant species. It seems to prefer 

 the leaf-nests, from which I have sometimes taken from twelve to 

 fifteen to a nest. 



Heterothrops nigra, Kr., is nearly always present, frequently in 

 profusion. 



QuKDius LONGicoRNis, Kr. — Thjs fine (Jiwditis is by no means 

 uncommon in the nests around Sudbury and Harrow, although as yet 

 I have not taken it in the Perivale district. 



QuEDius vexans, Epp. — This species is frequent in nests at Perivale, 

 sometimes six or eight occurring in one nest. It would seem to take 

 the place of Q. Umqicomis at Perivale, and gradually to become more 

 and' more scarce towards Sudbury; it is very rare at Harrow, the focus 

 of Q. lonyicornis. 



Oxytelus sculpturatus, Gr., and 0. tetracarinatus. Block, are 

 both fairly frequent. At present all my small Oxytelus have proved 

 to be the common species. 



Choleva angustata, F. — I took two J s and one $ from a nest 

 near Harrow. 



Choleva nigrita, Er. — A rare capture ; only a few examples have 

 been met with. 



This concludes the roll of species at present noticed in the district, 

 the result of two expeditions on January 19th and 22nd, 1910, each 

 of only a few hours.
