striated. Pronotal spine loug, sharp-pointed, roundly curved towards 

 the head. The spines on the sides of metanotum stout, obUque, short, 

 rounded and narrowed at the apex. 



Spinai'ia hhotanensis, sp. no v. 

 Length, 12 mm. ? . 

 Busa, Bhotan (Dudgeon). 



The resemblance of this species to S.jiavipennis in form and 

 coloration is very great ; the two may be separated thus : — 

 The radial, the second and third cubital cellules, and the 

 lower part from the recurrent nervure smoky, the basal 

 cloud reaching to the apex of the basal abscissa of 

 cubitus ; the depressed lower part of mesopleurse wide 

 at the base, gradually narrowed towards the apex, 

 closely reticulated-striated ...... hhotanensis. 



The radial, second cubital and base of third, and the base 

 of discoidal cellules unclouded ; the depressed lower 

 part of mesopleuraB not much narrowed at the apex, 

 irregularly striated and punctured .... flavipennis. 



The hind wings are clouded from near the middle ; the cloud in 

 the first cubital cellule is along the cubitus, extends to the apical 

 fourth, becomes gradually narrowed to a fine point, and extends 

 slightly into the discoidal cellule. The pronotal spine is long, curved ; 

 the top of the part in front of it is depressed, narrowed obliquely 

 towards the spine, the base rounded laterally, the middle with a slight 

 incision. Centre and base of metanotum irregularly, widely reticu- 

 lated ; the central keel larger than the others ; the apex with three 

 areae, of which the central is not so wide, and has a keel dow^i its 

 middle ; the lateral spines stout, oblique, wide at the base, narrowed 

 and rounded at the apex. All the abdominal segments are stoutly, 

 closely, longitudinally striated ; the ventral surface, the sides of the 

 basal two, and the apical segments are white ; the latter is narrowed 

 gradually to a long spine. Before the middle of the propleurfe are two 

 stout, roundly curved keels, close to each other, and with a short 

 oblique one in front. The keels bordering the scutellums are stout. 

 Last joint of hind tarsi black, as in fiavipennis. 



If it were not for the marked difference in the clouding of the 

 wings, I should have felt inclined to regard this species as a 

 form oi fiavipennis. 



NOTES AND OBSEEVATIONS. 



Notes on the Occurrence of Pyrameis cardui in the Early 

 Summer of 1906. — With reference to Mr. Adkin's interesting article 

 on the abundance of Pyrameis cardui in June of this year [ante, p. 173), 

 I think perhaps some observations I made on the occurrence of this 

 insect in the early part of the summer, or perhaps, to be more correct, 

 in the late spring, may be of further interest to your readers. All 

 during May I paid frequent visits to the coast between Eastbourne and
