NOTES ON LEPIDOPTERA IN MIDDLESBROUGH. 105 



coiumon as it usually is, and the oak trees did not show such signs of 

 the ravages of the larvce of this and other species as is sometimes the 

 case. I took three specimens of the pretty Tineid CerostoDia sojiiella 

 off sycamore tree-trunks. During the next fortnight about two dozen 

 specimens were taken in a very restricted locality, and in every in- 

 stance but one off the trunks of sycamore trees, although other trees 

 occurred close to them. 



On July 18th Veniiua camhrica and (Uindia uhnana were beaten 

 out. Several specimens of Scardia corticella were taken off two 

 decayed alder trunks (one tree), and during the next fortnight, I 

 noticed a good number more, all restricted to this one tree. 



July 20th gave me Axtlicna hUnneri, Dicti/opteryx loeffiiiniaiia, and 

 Penthinn corticana on birch. Grapholitha cinerana''' occurred during 

 the next fortnight, and I took about a dozen specimens of this Tnrtri.e 

 almost without exception resting on aspen trunks and consisting of 

 two forms, the grey and the grey with black markings. It was notice- 

 able that this species was out and over before G. nindla commenced, 

 and that none of the forms of niaella taken were in any way similar. 

 Prays, ciirtiselliis, Cernstoiiia ritella about wych elm, and C. antella about 

 wych elm and hazel occurred at this time. 



On July 25th I took Aryyreathia pyymaeella in the garden at 

 Middlesborough, it being very wet and cold weather for some days 

 about this time. 



On July 27th I took a single specimen of Paedhca rufiwitramr' in 

 fine condition. 



On August 3rd Kllopia prosapiaria and Larentia olivata, Pacdisca 

 corticana and Scardia arcellavvere beaten out. OcliMnJieimeria hisontella 

 occurred on a grassy hill-side flying about 2 p.m., and Batrachedra 

 praeanyiista was on oak and aspen tree-trunks, principally the latter. 



On August 5th Tortrix .vyloxtrana occurred among oaks, Paeduca 

 wlamlriana was beaten out of hazel, and Phihaloccra qiiercana out of 

 oak. 



On August 17th Oporahia filigrammaria occurred on the moors, 

 (jraplwlitha ramella and its dark variety about birch, and O. nhella 

 about sallows in a very restricted locality. A variable series of this 

 last pretty Tortrix was taken during the next few days. They were 

 usually found at rest on the sallow trunks but had a habit of darting 

 oft or dropping suddenly to the ground, and were most difificnlt to 

 follow. Lita fraternella, L. atriplicella and Cemiostoiim Hpartifi)lidla 

 were also taken on this date. 



On August 24th I met with Cidaria iniinnnata and Lita )naculca, 

 two specimens. 



August 25th produced Opostcya salaciella. 



August 31st Polia chi was taken, Teras candana was beaten out, 

 including the two or three varieties of this species, Pemnea schalleriana, 

 Deprcssaria c(Mella and Aryyresthia nitidella were met with, Cltelaria 

 hiibnerella was beaten out of hazel, Oecnpkora fulviguttella, and Fdachista 

 atricdiiiclla were common in a swampy locality. 



On September 8th two specimens of Kiipithecia fraxinata were bred 

 from this year's larvae.
