NOTES ON LEPIDOPTERA IN MIDDLESBROUGH. 103 



and until the end of the month. From a pairing I obtained ova, 

 which hatched out on June 19th, and the larvie of which had mostly 

 pupated before August 2nd. Sti[iiiio)wta dorsana: this Tor«?-ny occurred 

 fairly freely on the afternoon of May 25th, which was fine and warm, 

 flying from 3 to 4.30 p.m. on a railway embankment. The males Hy 

 very rapidly, but the females, of which a few were taken, are more 

 sluggish and more often found sitting about on the plants. Two or 

 three interesting aberrations were taken, two specimens havmg the 

 dorsal blotch divided into two parts, and one with the dorsal blotch 

 reduced almost to spots. The wonder is how this species continues to 

 exist in the locality, seeing that the herbage is annually cut close 

 down for hay early in July. Kj/hippiphura cirsiana was also flying 

 in this locality at the same time, (Tlypliij)teiijx ftmcunriddla simply 

 swarmed, a few Mtcroptenj.v caltlidla and a single specimen of 

 Coleophora fahncieUa were noted. 



On June 1st, Fentliina pruniana and L'ardia tripiinctana were 

 beaten out of hedges, Phoxopteryx imjrtillana were met with among 

 bilberry and Incitrvaria muacalella were flying about flr trees in late 

 afternoon. Adela riridella, GelefJiia ericetella and G. lowjicornis 

 occurred among heather, and several GlypJiipteryx jischeriella were fly- 

 ing in early afternoon about gorse in a hedge bank. 'Sivanniienlawiiria 

 coiiibineUa, Aryyrestliia cnrvella and Larerna heUerella were found in a 

 garden at Middlesbrough on June 6th. Specimens of L. atra 

 occurred about apple trees flying just before dusk early in August. 



On June 15th, Tinea iveaverelLci''- occurred among fir trees. I had 

 previously taken specimens in 1911, when Mr. B. A. Bower visited the 

 dib.trict with me and suggested that the specimens were probably this 

 species and not T. nit^ticella. On going through my series of T. 

 rasticella I found that they were all but one referable to u-eavevella. 



Art/yrest/iia conjnyella occurred freely about mountain ash until 

 well into July, 1 also took a few specimens of the unicolorous dark 

 bronzy-fuscous form ab. aerariella. Spilonata tninaculana first occurred 

 on June 16th. Hedya neylectana was found resting on poplais, 

 fencing, etc., on June 18th and throughout the remainder of the 

 month. luibolia pln»ibaria was flying about gorse on June 22nd, 

 and Acidalia fiuiiata occurred among bilberry, Melaniiype tristata 

 Tortrix viburnana also among bilberry, Mixodia sclinlziana on moors, 

 Eupoecilia viacidosana, Fhoxopteryx ndtterpacheriana and Ocnerostoiiia 

 piniariella, the last beaten out of firs. Tortrix costana, Elachixta 

 luticnmella, K. cenisella, K. triatoiiim and Bnjotroplia senectella were 

 taken in some marshy ground near Middlesbrough on June 27tb, and 

 on the same date Tortrix unifasciana was taken in the garden, this 

 last occurring very plentifully after this date. 



On June 29th I noticed Boiiibyx qiiercHs var. calliinae 2 , flying in 

 early evening; other species noted on this date being lietinia pinirorcnia 

 among pines, and also Stiymonota coniferana of which I took odd 

 specimens flying about Scots fir or beaten out of the branches on 

 two or three subsequent dates, the last taken being a perfectly fresh ? 

 on August 3rd. 



Coccyx vacciniana, Gelechia covfinix, about burnt heather on moors, 

 Bryotroplia desertella, a single specimen of Bracltycrosttata cinereila, 

 and Cedestis farinatella were met with. Of Dichroramplia tanaceti, 

 several were taken flying about Achillea )nillefolivm in the garden about
