204 THE ENTOMOLOGIST. 



ON SOME GEOMETRIDES COLLECTED BY PAYMASTER- 

 IN-CHIEP GERVASE F. MATHEW, R.N., ON THE 

 MEDITERRANEAN, &c. 



By Louis B. Prout, F.E.S. 



My kind correspondent, Mr. Gervase F. Mathew, having most 

 generously enriched my collection with a number of interesting 

 Geometrides collected by himself at various times in the above- 

 named (to us not too well known) region, I have thought it would 

 be of interest to publish a note on them in the pages of the 

 'Entomologist'; the more so as at least one of the records is 

 faunistically new, while I strongly suspect several of the others 

 to be so likewise. I shall arrange the species according to their 

 localities, making notes on the forms where needful. 



Vigo (July, 1886). — Acidalia ochrato, Scop., male ; A. interjectaria, 

 Bdv. (fuscovenosa, Goeze), dark ; PJiodostrophia vibicaria, CI., three 

 males, all of the frequent southern aberration strigata, Stgr., one 

 female of the (more beautiful) type "form, with broad rosy band, — all 

 four specimens rather small compared with those which I have from 

 Cuenca, Tragacete, aud Piedrahita ; Pseudoterpna coronillaria^ Hb., 

 two; Ematiirga atomarm; L., a large male with the ground colour bright, 

 and the mai-kings strong; Rho})tria {Gnophos!, Stgr. Cat.) asperuria, 

 Hb., one example, belonging to the unicolorous ab. pityata, Rbr. 



Lisbon. — ■Acidalia nexata, Hb., and Larentia malvata, Rbr., one of 

 each ; neither is included in Santos' (very meagre) Lisbon list (Jorn. 

 Acad. Sci. Lisbon, torn, x.), but A. nexata is recorded as Portuguese in 

 Staudinger's ' Catalog,' and our national collection has some nice 

 Lisbon examples collected by Eaton. 



Gibraltar. — Thamnonoma spodiaria, Lef. = semicanaria, Frr., Stgr. 

 Cat., one specimen. 



Nice (April, 1897). — Camptogramma bilineata, L., a rather large 

 specimen, glossy, and of a peculiar tint, the dark lines faint ; Minoa 

 murinata, Scop., two, both of the typical brown-grey continental form;* 

 Larentia riguata, Hb., two, rather strongly marked. 



Alghero, Sardinia. — Acidalia itnitaria, Hb., a rather small male, 

 May 27th, 1898. 



Malta. — Larentia fluctnata, female, dated March 3rd, 1897 ; an ex- 

 tremely interesting aberration, the markings being all excessively weak, 

 notwithstanding that the specimen is in immaculately perfect con- 

 dition; Eupithecla pumilata, Hb., two, bred in January, 1898; Rhodo- 

 metra {Sterrha, H.-S., nee Hb.) sacraria, L., a good male, April 19th, 

 1898 ; Acidalia virgularia, Hb., male, pale form (=:var. australis, Z.), 

 May, 1898 (is this not rather early for "gen. ffist."?) ; Aspilates 

 ochrearia, Rossi, male ; Anaitis plagiata, L., three, one (March, 1897) 

 being of medium size, the other two (October, 1897, and May, 1898) 



'^ Our British forms, though varying locally, are almost all intermediate 

 between this type and the ochraceous var. monochroaria^ H.-S., and probably 

 desei've a varietal name.
