508 Mr. Westwood on the Genus Slaphi/linus. 



find the Staphylinus noticed, as having been described, *' cum 

 vermiculo suo," by Mouffet; and of which genus five species were 

 possessed by Swaramerdam, " cum vermiculo et nympha qu£B 

 aliquanto obscuriora osteutat membra." The Vermiculus of the 

 Staphylinus^ however, (as Swammerdam calls it,) was described 

 by MoufFet as his 2d species of that genus, but is in fact the Larva 

 of Stuuropus Fagi, known by the English Collectors under the 

 name of the Lobster Caterpillar ! 



P. 60. In giving the description of a Larva, which I supposed 

 to be that of Aleochara fiiscipes^ I was influenced by a desire to 

 exhibit (by comparison with the Larva of the Siagonium and 

 PhUonthus) the differences existing between the immature states 

 of the insects belonging to the families Omalidce, Staphylinidce^ 

 and that which I had previously considered as forming the type 

 of the family Tachyporidce. As, however, it may perhaps be 

 hinted that as a small Ulster was the solitary companion of the 

 Aleocharas, there is a probability that the Larva in question might 

 be the young of some species of that genus, it will not be thought 

 irrelevant to introduce a short account of the Larva of Hister 

 cadaverinus, figured by Paykull in his Monographia Histeroidum, 

 which is a long, soft, and Avhitish Grub, with the head and first 

 segment of the body scaly, and channelled above ; the jaws 

 strong and advanced; the antennae short, and (as in the perfect 

 insect) thickened at their tips ; the joints of the body rounded 

 at the sides ; and the last joint terminated by a pair of short two- 

 jointed appendages, without any caudal tube. 



The characters above noticed, but more especially the jointed 

 anal bristles, will clearly shew that my supposed Larva of 

 Aleuchara, does not belong either to the Silphidce or Nitidulldce, 

 as suggested by Mr. Kirby ; indeed the figure of the Larva of 

 Nitid. grisea in the 1st vol. of the Linn. Trans,, although exhibiting 

 each segment of the body slightly projecting at the sides, has the 

 abdomen terminated by four small simple inarticulated setse bent 

 upwards, the two lowermost being considerably the longest. It 

 is also described as having two hind feet, which however are not 

 visible la the figure.
