20 THE entomologist's record. 



third and two-thirds, but one-quarter and three-quarters ; for example 

 two cross-bred sordiata paired together give three sordiata to one prunaria 

 among their offspring. Mr. Eaynor's experiments with Cidaria truncata 

 bear out this proportion very fairly, though there is a slight excess of 

 the type. 



Mr. Eaynor has done such valuable work in testing the application 

 of Mendel's law to Lepidoptera, that I do not like to let such a mis- 

 apprehension pass unnoticed, and am confident that he will be pleased 

 to find that his recent experiments supported the law instead of con- 

 tradicting it. 



i^OLEOPTERA. 



CoLEOPTEKA IN THE Enfield DISTRICT. — Amongst the accumulation 

 of beetles, with which I have filled numerous store-boxes during the 

 seasons of 1903, 1904 and 1905, are a few species which appear to be 

 worth recording. Cychrus rostratus, one under loose beech-bark at 

 Enfield. Notiophilus rufipes, a few amongst dead leaves. Licinus 

 silphoides, one running upon the pavement near Enfield Town Station. 

 Platyderus raficollis occurs rarely under loose bark, and in grass tufts 

 at Edmonton. Amara convexiusvida, several by sweeping herbage on 

 3ld rubbish heaps at Edmonton. Calathus fuscus, a few under stones 

 and rags. Sphodrus leucophthalmus, in a cornshop at Edmonton, where 

 also occurred — Ptinus fur, P. brnmieus, P. tectus, Niptus crenatus, N. 

 hololeucus, Tenehrio inolitor, T. obscura, Tribolium confusum, Mycetopharjus 

 quadriyuttatus, etc. One specimen of Bembidium quinqiiestriatum 

 occurred under a stone at Enfield in October. B. flammulatuin, B. 

 articulation, and B. varium in numbers at Edmonton and Enfield. 

 Dromins ayilis occurs at High Beech and Waltham, but I have not seen 

 it at Enfield. Xantholimis falyidm occurs occasionally on pavements, 

 etc. Oxyporus rufus was swarming in fungi at Edmonton during the 

 summer of 1903, but I have not seen it since. Coprophilus striatulus 

 taken occasionally on pavements and in decayed vegetable matter. 

 Homalium caesuni ab. tricolor, H. atriatmii, H. vile, H. concinnum, H. 

 iopteruni, in bark, fungi, etc. I am indebted to Mr. Donisthorpe, who 

 discovered two specimens of Hapalaraea pyymaea amongst my collection 

 of Homalii. Proynatha quadricornis and its curious larv« swarm 

 under damp elm-bark in a timber-yard at Enfield. A nice series of 

 Ayathidium niyripenne occurred in a similar situation. Eumicrus 

 rufus, a few have occurred under bark of beech, elm and fir. Symbiotes 

 latus turns up pretty frequently under elm-bark at Enfield, and about 

 twenty examples occurred in powdery fungoid matter under alder- 

 bark near Waltham Abbey. Triplax russica, Paromalus Jiavicornis, 

 Pendrophilm punctatus, Abraeus globosiis, and a few species of Hister 

 occur in fungi and under bark. Nitidula rufipes, swarming in the 

 dried-up carcase of a fowl at Cheshunt. Laetnop/doeus bimaculatus and 

 L. ferruyineus under sycamore-bark at Enfield. Atomaria fimetarii in 

 stems of fungi at Edmonton, and A. fumata in fungi at Enfield. 

 The whole of the Mycetophayidae occur at Enfield, with the exception 

 of Mycetophayus populi and M. fulvicollis. The little M. quadriyuttatus 

 is abundant in the rotten wood of an old elm at Enfield ; an aberration 

 with six distinct spots forms the greater part of this colony. I have 

 not seen this species alive in the open country elsewhere in the district, 

 it appears to be confined to the one tree. The common M. 4-pustulatus
