evident, especially in the anteniiEe; but if we proceed in the 

 comparison we shall find that they gradually approach, so 

 that at last there is little to distinguisii the genera excepting 

 the length of the 3rd joint of the antennae. I cannot speak 

 with certainty regarding thetrophi, not having examined them 

 sufficiently, but 1 must not omit to notice a remarkable de- 

 parture from the typical structure, which Mr. Haliday has 

 pointed out to me in a species allied to Selandria, with very 

 short pal[M, containing only 5 and 3 joints instead of 6 and 4. 

 Mr. Haliday has only seen the males which he took at Holy- 

 wood, and has named them seminigra, and perhaps Brachy- 

 thops may be considered an appropriate generic name. 



In addition to the 42 species of Allantus recorded in the 

 Guide, I am now able to add three more. The following 

 sections may probably be found preferable to Dr. King's, 

 which are based on the colour of the antennje. 

 * AnteniKS sJiort^subdavate. a. Hinder tarsi stout in the males. 



1. Scrophulariae Linn. — Panz. 100. 10. — rusticus Srhr. 



2. captiva St. Farg. 88. 256. First detected by Mr. Shuckard. 



3. Thompson i Curt. MSS. 



Male black ; clypeus, base of antennae, humeral spots, 2 on 

 scutel, margins of 1st and 4th, sides of 5th and apical 

 segments yellow: legs yellow, upper side of thighs, apex 

 of tibia? and tarsi black, hinder dilated. 

 1 have the pleasure of dedicating this pretty species to my 



friend C. J. Thomson, Esq., who was present when I took it 



at Mickleham the middle of August. 



4. flavipes Fuurc. — Curt. Brit. Ent. pi. 764. (J. — (\\spd.v King. 

 This species was first observed by Mr. Shuckard in Battersea 



fields, where it appeared in abundance the end of June. Wish- 

 ing to see the insect alive, I went to the spot the beginning 

 of July, when 1 found 2 females upon the flowers of Sinajns 

 nigra and also 6 larvce, one of which I have figured : they 

 were feeding on that plant, and I believe upon S. alba, pi. 

 546 ; they ate the leaves, stalks and flowers ; one soon changed 

 its skin, when it lost all the black spots except those on the 

 head, and it buried itself on the 17th, and the others success- 

 ively, but unfortunately I could not rear them : there is little 

 doubt however that they were the larvee of A.Jlavipes. 



Dr. Klug having described 2 species of Allantus under the 

 name of di spar, I have lound it necessary to revert to Four- 

 croy's name, although it is not perhaps so appropriate. 

 h. Hinder tarsi alike iu both sexes. 



5. rusticus Lifin. — carbonaria Fab. — Panz. 71. 10. — notata 

 Panz. 64. 10. ?. 



** ylntenncc longish,Jiliform : a. hinder tarsi stout in the males. 



6. zonatus Panz. 64. 9.— equestris Panz. 107. 6.— succincta 

 Do7i. 13. 441. 2. 



b. Hinder tarsi sle^ider in both sexes. 



7. lividus Linn.— Panz. 52. 6. ? .— Carpini Panz. 71. 9-6- 

 The plant is Sinapis nigra, Common Mustard.
