524 MERISTIC VARIATION. [part i. 



a number of lamellae, some like normal lamellae, others quite 

 irregular. As far as I could make out, the divisions were as 

 shewn in the figure, and I have affixed numbers to the several 

 parts in illustration of their possible nature. The appearance 

 suggests that there is an irregular repetition of a pair of clubs 

 peripheral to the normal antenna, but I can form no opinion 

 as to the morphology of the parts. Originally described by 

 MoCQUERYS, Col. an arm., 1880, p. 12, fig. [Description and 

 figure altogether misleading.] 



Paired extra Palpi. 



805. Bembidium striatum (Carabidae) : left maxillary palp arises by a 

 first joint enlarged towards its apex, bearing three separate terminal joints 

 instead of one. Of these joints one stands apart on a small process of 

 the first joint, but the other two are placed close together, on either 

 side of the apex of the first joint, and diverge from each other at about 

 a right angle. Jacquelix-Duval, Ann. Soc. Ent. France, 1850, Ser. 2, 

 viii. p. 533, Plate xvi. 



806. Helops sulcipennis (Het. ): supernumerary, partially double 

 apical joint arises from the 2nd joint of right maxillary palp. It is 

 set on at right angles to the plane of the normal palpus. Jayxe, H. F., 

 Trans. Amer. Ent. Soc., 1880, viii. p. 1QI, jig. 14. 



807. Euprepia purpurea (Arctiidse): a specimen in which the right wings and 

 antenna were male and the left wings and antenna female, is declared to have 

 possessed an extra pair of palpi. [No sufficient description of this extraordinary 

 occurrence is given; and as the repetition of the palpi is only incidentally mentioned, 

 it may be doubted whether a full examination was made.] Freyer, C. F., Beitr. 

 zur Schmetterlingshunde, 1845, Vol. v, p. 127, Tab. 458, Jig. 4.
