and of some species of Atractodes are also very similar. I 

 have not heard of any of the species being bred from the 

 pupa ; and when my Guide was published, one only was 

 known to inhabit these Islands, but since that period the fol- 

 lowing have been detected in England and Ireland ; and I am 

 indebted to A. H. Haliday, Esq. for specimens, as well as the 

 loan of the example figured. 



1. S. gagates Grav. v. I. p. 667. n. 288. — Curtis's Guide. 

 Length If to 2 lines. Black, shining; antennae often fer- 

 ruginous beneath at the base; stigma and nervures brown, 

 ochreous at the base; abdomen of the male sometimes with 

 an ochreous band at the base of the second joint. Legs rufous; 

 coxae, especially the hind pair, generally black, tips of tarsi 

 dusky. 



June and August, Ireland, Mr. Haliday : I took females 

 in a garden at St. John's Wood, the end of September, and I 

 believe in May also; and another which was much larger at 

 Rhennes in France, the beginning of June. 



2. S. Pavonije Scop.— Grav. 1. 671. 2S9.—Curt. Guide. 

 Similar to No. 1. but the antennae are ochreous at the base, 



and the legs are of a paler colour : I suspect it is merely a 

 variety. Not uncommon in Ireland, from June to August. I 

 have also taken it with the last. 



3. S. dryadum Hal— Curt. Brit. Ent. pi. 388. 



Black, shining: antennae straw-colour at the base, the first 

 joint sometimes with a black spot on the upper side : wings 

 with the stigma and nervures pale brown, yellowish at the 

 base : abdomen in the male with a pale ochreous band at the 

 anterior margin of the second and third segments ; female with 

 a broad ochreous stripe down the back of the second, third and 

 fourth segments, a spot at the tip of the petiole (which has a 

 channel down the middle), and the margin of the second seg- 

 ment pale ochreous. Legs ochraceous, tips of tarsi blackish. 



Obs. Sometimes the abdomen of the female is entirely 

 black, and this sex has only fourteen joints in the antennae. 

 Both sexes of this new species were taken on oak-trees in 

 Galway, Ireland, by Mr. Haliday. 



4. S. blandus Grav. 1. 672. 290.— Curt. Guide. 



Female 2 lines long : black, shining ; first and second 

 joints of antennae ochreous beneath ; second and third seg- 

 ments of abdomen rufous; ovipositor exserted but very short: 

 legs pale rufous, posterior coxee black at the base. 



Rare : taken by Mr. Haliday in Ireland. 



The Plant is Sherardia arve^isis (Little Field-madder).
