216 MR. CURTIS ON THE GENUS MYRMICA, 



bear that construction, excepting the postscutel : the profile of the petiole and the spines 

 given in Ny lander's plate * agree, however, very well with our insect. 



It is strange that the males of this species should not have been detected in England, 

 as the neuters are not uncommon, and the females, if such they be ?, have also been found. 

 These females are so distinct from any other species, that I had given them the name of 

 maculipes. The form of the head, thorax and nodules is very peculiar. 



In the middle of April 1829 I collected some of the neuters at Southend : I found them 

 at the roots of plants at the base of the cliff, and subsequently in June I met with a small 

 variety at Darent in Kent. Mr. Smith has found them not uncommon at Sandown Bay 

 in the Isle of "Wight, and also at Folkestone. The two females alluded to, agreeing with 

 M. Nylander's M. fuscula, were discovered by Mr. Dale, under a stone at Charmouth in 

 July, and they had lost their wings.

p. 259?. 



This species requires investigation. I have a pale neuter, which agrees with one of 

 Nylander's specimens ; I believe it came from Dorsetshire : Mr. Smith has taken others 

 on Shirley Common, Surrey ; and Mr. Wing met with several under the bark of an oak- 

 tree at Brixton the beginning of April. They were all neuters.

The neuters of this insect were taken I believe by Mr. Dale in Dorsetshire. 



11. M. graminicola, Latr. Hist. Fourm. p. 255. 



On the 20th of May I took a neuter on a bank at Dinton near Wilton, and I believe it 

 is abundant under stones on the Downs there. Mr. Smith finds it under stones at Wey- 

 bridge, Surrey. 



Latreille's descriptions are too vague to enable me; without seeing his examples, to 

 decide regarding this species. When I published the Genus Myrmecma in 1829, I 

 thought it possible my species might be the one indicated in the ' Histoire naturelle des 

 Fourmis,' as the wings of the male F. graminicola are described as entirely blackish, and 

 at that time I only possessed that sex ; but Latreille compares his insect to the F. rubra, 

 and makes no mention of the difference in the neuration of the wings, which would 

 scarcely have escaped so acute an observer, especially as he remarks that the nervures 

 are black ; and as our females agree in no respect with Latreille's description, I cannot 

 think that our insects are identical. M. Foerster seems to be unacquainted with the 

 neuters and females of M. graminicola, and the male which he describes is undoubtedly 

 my Myrmecina Latreillii. 



12. M. tjnifasciata, Latr. Hist. Fourm. p. 257. 



This pretty species is recorded by Mr. Smith as inhabiting moss in Coomb- wood, Surrey. 

 The only specimens I possess are apterous females and neuters. I found them under the
