The LaUa Marnia specimen is small and very blue. 



Mr. Oberfchiir considers that there are two races of cognate in Algeria : a larger, 

 duller, more transparent form from Sebdou, Lambessa, and Ain Draham, and a 

 smaller, brighter, and more densely scaled form from Aflou. 



My series, apart from Khenchela examples, is too small to enable me to judge 

 on this question, but I can clearly perceive, from the Khenchela series, that Mr. 

 Oberthiir is quite right when he says that the length of the pectinations of the 

 antennae is not a constant and therefore not a vaUd character. The Guelt-es- 

 Stel (J is a dwarf (length of forewing, 14 mm. ; expanse, 31 mm. ; ordinary (J<J, 

 length of forewing, 19 mm. ; expanse, 42 mm.). 



The Tring series comprises 101 Mauretanian specimens. 



41. Procris cirtana cirtana Lucas. 



Procris cirtana Lucas, Explor. iScient. d'Alg., Anim. Arctic, vol. iii. p. 373. No. 76. pi. 3. f. 2 (1849) 

 (Constantine, Koudiah-Ati). 



We ourselves have taken this tiny species at Hammam R'ihra, Khenchela, 

 Hammam Meskoutine, and Tlemcen. The blue form is ab. bakeri Kirby = orana 

 B. Baker nee Aust. Mr. Oberthiir informs us that he possesses the type-specimen 

 of Procris orana Aust., and that he has convinced himself that it is identical with 

 cirtaiia. If this is really the case, the foUo-ning species must receive a new name, 

 for it is certainly not cirtana Lucas. Until, however, we can compare itniorpho- 

 logicall}' \\ith the ? type of Austaut, I prefer to retain the name of Austaut for 

 the smaller form of what Oberthiir calls tenuicornis. The Tring series comprises 

 77 specimens.

Ino orana Austaut, Le Natural, vol. ii. p. 284 (1880) (Oran). 



The type of orana Aust. was collected at Oran in April by Dr. Codet, and is 

 in Mr. Charles Oberthur's collection. The latter, as stated before, declares it to 

 be identical with cirtana, in which case the present insect requires a new name ; 

 the figure given by Mr. Obertliiir is, however, very different from cirtana Luc, 

 and wthout a close morphological comparison with a ? of the present species I
