chrysalis state about four or five weeks, and I believe the young 

 larvae hybernate. Although I have searched repeatedly for a 

 second brood, I have never found one." 



We have now got from Chester to Warrington, twenty miles, 

 roughly speaking, and north-east. From Warrington to Bolton 

 is another twenty miles, measuring by the same standard of 

 accuracy. Here, although search has been made for years, and 

 by careful entomologists, the late brood has never yet been 

 found. Let us continue our trip some forty miles to the north- 

 west, and we find Mr. G. T. Porritt at Morecambe from Aug. 11th 

 to Aug. 31st, 1893. In Ent. Mo. Mag. for January, 1894 (p. 12), 

 we find Mr. Porritt writmg as follows: — ''At dusk P. festucce 

 occurred on all the ditches (Hey sham Moss), and was not un- 

 common." What, then, was P. festucce doing at Bolton at the 

 same time — forty miles to the south ? It was either on the 

 wing as well, as a second brood, or the progeny of the only brood 

 (.Juiie-July) were about to hybernate as eggs or larvae. The first 

 of the three probabilities must be dismissed iu the face of evidence 

 which cannot be set aside, and either the second or third brings 

 the Bolton form up to the importance of a variety. As far as 

 coloration is concerned, variation of the moth is hardly per- 

 ceptible. The Chester insect, I think, is a little darker than the 

 Bolton one. The ''gold spots" vary a little in shape, size, and 

 proximity in all localities, but I can meet with no confirmation 

 of a reputed form with confluent spots.

IRRORHOTIDES: A NEW GENUS OF ATEUGHID^, WITH 

 A DESCRIPTION OF A NEW SPECIES. 



By John W. Shipp. 



Irrorhotides, n. g. 

 Body similar to Actinophorus. Thorax and head resembling 

 Pachysoma. Fore legs similar to Sehasteos, Head not f ree ; 

 clypeus 6-dentate, the two centre teeth projecting. Thorax 

 wider than the elytra, compressed transversely, with the lateral 

 margins strongly curved and crenulate, wider in the centre, 

 narrower at the anterior and posterior angles : apical margin 

 smooth ; posterior margin finely crenulate, with a concave curve, 

 and slightly sinuated, posterior angles not so wide as the 

 anterior angles, acute, and terminating in a small tubercle or 

 spine. Elytra cordiform, slightly convex, as wide as long, 

 humeral angles acute; lateral margins curved towards apex, 

 strongly emarginate ; basal emargination crenulate. Pygidium 

 obtusely triangular. Anterior tibiae flat, elongate, 4-dentate on
