252 THE ENTOMOLOGIST. 



species are enumerated in the list ; of these four hundred and forty-four 

 were taken in the immediate neighbourhood of Reigate or Red Hill, 

 fifty-seven within a radius of from five to six miles, and forty-eight 

 others at places distant from seven to twelve miles from the town. 



Vanessa cardui. — What has become of Vanessa cardui ? In my 

 rambles around this neighbourhood in the late spring months of the 

 present year, sundry more or less tattered individuals of this species 

 were occasionally met with, and on June 11th, a warm sunny day, it 

 was flying quite commonly over a rough field not half a mile beyond 

 the continuous streets of houses that, in this quarter, form the outer 

 border of London ; I waited for some little time watching them, and 

 several times saw two or three of them flying together. On comparing 

 notes with my friends, I learned that they, too, had found the species 

 commonly in many parts of the country, and I naturally looked for an 

 abundant autumn emergence. But quite the reverse is the case. 

 During the later half of August and up to the present time I have paid 

 periodical visits to the same field and neighbourhood ; on many of 

 these occasions the days have been delightfully warm and sunny, but 

 not one individual has come under my notice ; and during a stay of 

 some three weeks at Eastbourne, terminating on August 14th, one 

 solitary example was the only representative of the species that I met 

 with. Vanessa atalanta was fairly common in spring, and both here 

 and at Eastbourne I found it unusually abundant this autumn. The 

 two species have much in common, and the thought that occurs to 

 one's mind is, what special circumstance could have favoured the 

 propagation of the one without being equally advantageous to the 

 other? I may have been singularly unfortunate in my search for 

 the autumn brood of cardui; if so, perhaps some of our more fortunate 

 country friends, who have better opportunities for observation than we 

 Londoners, will be able to throw a different light on the subject. —

A Correction. — In my paper " On the Nomenclature of the Rhyn- 

 chota. Parti." (Entom. 1899, pp. 217-21), I proposed to ''treat 

 1 Pentatoma, Olivier,' as a no men nudum." After further consideration, 

 it appears to me that this would not be in accordance with the strict 

 law of priority, for a genus once diagnosed — however insufficiently — 

 ought to be treated as valid, if at all possible. The case is certainly a 

 very awkward one, and the only way out of the difficulty seems to be 

 to treat Pentatoma, Oliv., 1789, and Cimex (Linn., 1758), Fabr., 1794, 

 as genera practically co-extensive but not co-typical. In the synonymy 

 I proposed (p. 220) no. 1, Cimex, will remain unaltered; for no. 2 read: 

 "Pentatoma, Oliv., 1789. Type, rujipes, Linn., Lam., 1801. 



At p. 220, line 26, for "nigrideus" read "nigridens"*, line 36, for 

 " Philontochila" read " Philontocheila.'" — G. W. Kirkaldy; Sept. 16th. 



Triph^na orbona, var. — On July 30th, 1892, 1 captured, in Cambs, 

 a specimen of T. orbona resembling fig. 3 in "Newman." It was 

 exhibited at the meeting of the South London Entomological Society 

 on October 13th in that year. I have now to record a second example, 

 perfectly fresh, taken this year at sugar in my own garden at Wood-
