Mr. T. V. Wollaston on the Coleoptera of St. Ihlcnn. 29 



foiuul in St. Helena, answering to tlic Fa1)rieian diagnosis, 

 wiiicli has escaped detection in more recent times ; ;uid my 

 reason for regarding it as an Asjndomorpha (a gcnns wliicli 

 occurs in western Africa and tlie Cape -Verde archipelago) is 

 simply because Uoheman, in his Monograph of the family, 

 cites the Cassidn miliar is of Fabricius as a member of that 

 particular genus. Yet, on the other hand, l^ohcman does not 

 acknowledge the species which he has identified with the 

 Fabrician one as a native of St. Helena at all, but, rather, of 

 the East Indies, Java, Celebes, China, and the Phili])[)ine 

 Islands, which at once raises a geographical difficulty which 

 it is not easy to solve. But, as there appears no cause (in the 

 absence of any kind of explanation by Boheman) for assuming 

 the originally asserted habitat^ of Fabricius, to be incorrect, I 

 prefer the contrary conclusion, and should be inclined to think 

 that Boheman may himself have been mistaken in identifying 

 a Cassida of Eastern Asia with one {per/iaps closely allied) 

 from St. Helena. At any rate, as I have no evidence (beyond 

 the tacit assumption of Boheman) that Fabricius and Sir 

 Joseph Banks were alike in error concerning the country from 

 which the original C. miliaris was received, I have no choice 

 but to include the species in the present memoir. 



Fam. 23. Coccinellidae. 

 Genus 41. Cydonia. 

 Mulsant, Sdcurip. 430 (1851). 



64. Cydonia lunata. 



CoccincUa lunata, Fab., Svst. Eiit. 8G (1775). 



, Id., Syst. Eleiith. i. 384 (1801). 



Cydonia lunata, Muls., Securip. 431 (1851). 

 , WoU., Journ. of Ent. i. 214 (1861). 



This curiously and prettily marked Coccinellid appears to 

 be common in St. Helena, where it has been taken abundantly 

 by Mr. Melliss and ]3reviously also by Mr. Bewicke and others. 

 Indeed, although with a wide geographical range (it having 

 been recorded from Senegal, the Cape of Good Hope, Caffraria, 

 Madagascar, the islands of Bourbon and Mauritius, the East 

 Indies and Java), it was originally described by Fabricius (in 

 1775) from St.-Helena s])ecimens, now in the Banksian col- 

 lection ; and therefore, whatever doubt may be entertained as 

 to the claim for specific separation of some of the extreme 

 states which have been ascribed to it, there can at least be no 

 question about the St. -Helena form, which must of necessity 

 be looked upon as the typical one.
