amongst the coiuiuou and variable C. niffcllns, to wliicli it is generally 

 similar. I have collected at Lumsden myself, but not so late in the 

 season. Type in Oxford University Museum ; Dr. Longstaft" very 

 kindly gave me one of the other examples. This makes the 38tli New 

 Zealand Crambns, all endemic, besides an endemic genus developed 

 from Crambus (Orocrambus) with six species ; whilst in Australia 

 there are only two species of Crambus, both immigrants.

HILARA AERONETHA, Mik : A DIPTEEON NEW TO THE BRITISH 



LIST. 



BY A. E. J. CARTER. 



The publication of the third part of Dr. Lundbeck's excellent 

 " Diptera Danica " enables me to identify a specimen belonging to the 

 genus Hilara which I have had unnamed in my collection for some 

 time. The specimen in question is a (J , taken July 7th, 1907, at 

 Comrie, Perthshire, and, I may add, is in beautiful condition. At the 

 time I failed to make it agree with any species in our List, but what it 

 might be I was unable to tell. Working now with the key given by 

 Lundbeck, my insect runs down to aironetha, Mik, and it agrees with 

 the detailed description given, but the apex of the second antennal 

 joint is distinctly reddish, while Lundbeck says " antennae black." 



The species is near interstiyicta, Fin., and maura, F. (both of which oc- 

 curred at Comrie), but is quite distinct. Frons narroiv. Thorax dark brownish- 

 grey, with a dark median stripe and sides. Dorso-central bristles in one row, 

 acrostichal bristles in four rows, one hvuneral, two post-humeral, three noto- 

 pleui-al, and two alar bristles. Scutellum with four bristles. Humeri with a 

 red spot. Abdomen grey, with a median stripe, and hind margin of the seg- 

 ments ash-grey in certain lights. Legs dark, knees reddish. Front metatarsus 

 slightly thickened, shorter than tibia. Leg bristles not strong. Wings yellow- 

 tinged. Exp., 6 mm. 



Dr. Lim.dbeck points out that Mik's description is not quite in 

 accordance with that given by Strobl, who apparently described the 

 species in the same year. In my specimen the acrostichal bristles are 

 regularly quadriserial, the fork of the cubitus is nearly straight, 

 branches off almost regularly, and ends very slightly nearer the radial 

 than to tlie cubital vein. The halteres are yellow, base of the knob 

 darker. It thus agrees, as do the Danish examples, with Strobl' s de- 

 scription.
