It is most difficult from imagines to identify any of the three species of 

 Heterogynis, but I have bred series of true penella from the Riviera, Digne, etc., 

 and I found a large number of larvae and pupae (cocoons) at Hanimam R'ihra, and 

 therefore as tlie latter agree with Dr. Chapman's cocoons of canalensis I have come 

 to the conclusion that the Algerian Heterogynis is affinis and not penella, as Mr. 

 OberthilrbeUeves. I did not succeed in breeding many Hammam R'ihra imagines, 

 as most of the cocoons were destroyed bj^ an accident. The Tring series number 

 103.

We have never found this ourselves, and I have received it from Guelt-es- 

 Stel, Masser Mines, and Oued Hamidou.

[Cerura interrapta and bifida. 



Mr. Oberthiir records both interrupla and bifida from Algeria. This I 

 believe to be an error ; for. owing to various species extending over countries 

 from Algeria to Wladivostock having the antemedian broad band occasionally 

 interrupted, it has been the custom on the continent to lump a number of species 

 together as interrupta. 



The history of interrupta is as follows : H. Christoph in the Stettiner 

 Entomologische Zeitung for 1867, p. 233, describes a new Cerura from Sarepta as 

 Harpya interrupta sp. n. and gives the following diagnosis : " Alis anticis cre- 

 taceis basi margineque postica nigropunctatis, fascia ( <?) in medio late inter- 

 rupta, (?) utrinque sinuata nigra — posticis albidis. Exp. al 47 mm. Long. 

 Corp. 20 mm." 



C'hristoph in the detailed description lays great stress on the chalk-white 

 ground-colour, large size, robust build, and much broader wings as compared 

 with Centra bifida. He also points out that his ij only has the band broken into 

 two spots, while the ? has a complete band though constricted in the centre. 

 After this, in lH82in the Horae Societafis Entontologime Rossime, S. Alph^raty 

 described a Harpya petri, p. 37. t. 1. fig. 36, which is much greyer and has a 

 complete band. Dr. K. Griinberg in 8eitz, Grossschmetterlinge der Erde, cites 

 this as a dimorphic form of interrupta, and declares that the latter occurs in 

 Sarepta, Caucasus, the whole of Asia Minor, Persia, Kurdistan, Syria, and Tunis.
