204 THE ENTOMOLOGIST. 



ON SOME GEOMETRIDES COLLECTED BY PAYMASTER- 

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

 MEDITERRANEAN, &c. 



By Louis B. Prqut, 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 ochrata, Scop., male ; A. interjectaria, 

 Bdv. (fuscovenosa, Goeze), dark ; RhodostroiMa vihicaria, 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, and Piedrahita ; Pseudoterpna coronillaria, Hb., 

 two; Ematurga atomaria, L., a large male with the ground colour bright, 

 and the markings strong; Ehoptria (Gnophos!, Stgr. Cat.) asperaria, 

 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, tom. 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. — T/iavmonoma spodiaria, Lef. = semicanaria, Frr., Stgr. 

 Cat., one specimen. 



Nice (April, 1897). — Camptorjramma hilineata, L., a rather large 

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

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

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



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

 May 27th, 1898. 



Malta. — Larentia fluctuata, 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; Eupithecia piimilata, 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. aest."?) ; 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. tnonochroaria, H.-S., and probably 

 deserve a varietal name.
