wires, secured from the groove of the jam pot to the wire ring. A propagating 

 aeed-pan, or other suitable vessel must, of course, be substituted for the inverted lid. 

 Larvse will be found to find their way to the soil readily enough through the 

 interstice which is left between the wire ring and the jam pot. 



With a few remarks on the ' breeding house ' I close this chapter on ' cages.' 

 The breeding house, or apartment to be used for the purpose, should, of course, 

 be constructed, or chosen, with a view to the health of the occupants, and the following 

 conditions should be taken into consideration. Aspect. — One side facing the east, 

 at any rate, should be provided with a window, in order (hat the rays of the 

 early morning sun may gain admittance : this, with manj' larvae, is a condition of 

 paramount importance. Ventilation. — This should be complete, but so managed 

 that thorough draught be avoided, at the same time that the apertures, by which 

 it is effected, are sufficiently small to prevent the ingress of ' natural enemies ' to 

 our nurseHngs ; for bringing this about, the free employment of finely perforated 

 zinc in the construction of the breeding house is of the utmost utility. Tempe)'ature. 

 — This ought never to be too high, a roofing of Portland cement (flat tiles being 

 embedded in it for the purpose of 'tying 'it together), being nearly white when 

 dry, affords the greatest protection against the vertical rays of the sun, but, in 

 addition, when the weather is excessively hot, watering the floor and ground 

 adjacent to the breeding house may be employed with advantage. Space. — As 

 much room as possible should be allowed ; the more the better. Light. — It is 

 rather a disputed point whether a large or small amount of light is advantageous 

 in a general way : my own impression is that some larvae thrive best v?ith plenty 

 of hght, others in comparative darkness, and I think it may be taken as a criteriou 

 that if the perfect insects are day flyers (such as butterflies for example), their 

 respective larvae will be found to thrive best with a more or less abundant supply 

 of light ; while if they shun light (as the majority of the Noctuce), their larvae will 

 probably get on better in a darkened situation, &c. ; the apartment should 

 therefore be constructed with a view to this, and the cages arranged accordingly.

Notes on Micro-lepidoptera occurring near Haslemere. — The following list of 

 Tineina, captured in this neighbourhood during the last season, may possibly be of 

 interest. I omit, of course, those that have appeared in former communications. 



Xysmatodoma melanella. — Occurred in the middle of June, on an old fence, on which 



I had also found the cases in the spring. 

 ilicropterym calthella. — Where there are no flowers of Caltha palustris, or buttercup, 



this species frequents those of Cardamine pratensis, and even stitchwort and 



spurge. I have also observed it commonly running over hazel leaves in 



the copses. 

 M. amncella. — In marshy places in the early part of July, running over the leaves 



of Epiiobwm angustifolim,m. I have also found it in hedges among beech bushes. 



M. aalopiella. — Among birch bushes on the side of a wooded hill. 

 M. SpcurmoAinella eeems to prefer low birch bushes on the heaths.
