Tinea mauritanica, n. sp. 

 Alee anticcB ferriiginece nitidce unicolores. Ala postlccefasco-cinerecE. Corpus 

 sat robustum, caput ferriigineum. 



The anterior-wings are uniform ochreous rust colour, without any markings, and 

 slightly lustrous, with fringes of the same hue. The hind-wings are dark grey with 

 rather paler fi'inges. 



Head and thorax same colour as anterior-wings ; abdomen as posterior-wings. 

 The under-side of both anterior- and posterior- wings is dark lustrous brown. 



In one specimen the colour is much darker than in the other, the fore-wings 

 being almost of a dark brownish-red hue, with browner posterior- wings. 



This species, which comes very near to chrysopterella, was taken 

 rarely at Guelma in June, and measures from 12 to nearly 14 mm. 

 Two (J are now in my collection. 



There should be no difficulty in separating this species from 

 chrysopterella, as its colour is uniform dull red, while the latter is of 

 an almost orange hue, some specimens being of a bright orange. It 

 is also a smaller insect than chrysopterella, and the fringes of all the 

 wings are much shorter. Yet, it is just possible, it may be only a 

 dark form of chrysopterella. 



Pleueota ocheeostrigella, n. sp. 



AlcB anticcB aureo-ochracea, vittafusca prope costani ohscuriore. Alee posticce 

 fusco-cinerece. Palpi capite et thorace longiores. 



Anterior- wings uniform pale golden-ochre, with the longitudinal stripe near the 

 costa of a darker brown, and fairly distinct. The fringes are also of an ochre colour. 

 The apex is very acuminate, almost sinuate. Posterior-wings dark grey with paler 

 fringes. 



Head and thorax pale ochre colour. Palpi ochre coloured, irrorated beneath 

 and outside with black, the end joint being very nearly as long as the head, and 

 their total length being rather longer than the head and thorax. Abdomen darkish 

 grey. 



The ? is rather paler in colour, with a more distinct stripe, and much lighter 

 hind-wings. S measures 21 mm. ; ? , 23 mm. 



This species, which will precede metricella, was taken at Guelma 

 in June ; a ^ and $ being in my collection. 



I'rom metricella it may be distinguished by its deeper and more 

 golden colour, the former insect being much paler, and with a very 

 slight bronzy hue. In metricella also the costa is much paler than the 

 rest of the wing, which is not the case with our species. The palpi 

 are also decidedly longer in the present insect than in metricella. 



Pleueota algeeiella, n. sp. 



Alee, anticee flavo-ocJiracea, vittis dualus, costali et centrali, argenteo-albidis, 

 vitta media dentata, cum margine interiore jjallidiore. Alee posticce cinereee. Palpi, 

 cap tie et thorace longiores.
