Habitat : on stem of Oojfen araMca. Java (Coll. Zimm., No. 27). 

 The puparia are usually concealed beneath the superficial corky 

 growth, and probably owe their flattened form to this habit. 



This species belongs to the group of which M. pomorum and M. 

 citricola may be taken as types. The stout flattened and corrugated 

 puparium and the conspicuous double series of dorsal pores on the 

 pygidium of the $ , will serve to distinguish the present species from 

 its nearer allies.

Odontxus inobillcornis, F., at Downham, Norfolk. — On July 13tli, whilst moth 

 catching, I took a fine male specimen of Odonta'us mobilicornis, F., flying, just as 

 it was dusk. — Robert S. Smith, Junr., The Laurels, Downham : Aug. 1th, lOOl. 



[Many years ago Stephens recorded this species from Norfolk, so this capture 

 is interesting as confirming his record. — W. W. F.]. 



Plagiodera versicolora, Laich., in abundance at Oxford. — This beetle is not 

 usually regarded as at all common, and I never saw it alive until July 23rd last, 

 when it occurred in such numbers as to be considered almost as a pest. I met with 

 it on this year's shoots, growing up from the stumps that had been lopped in the 

 previous winter, of a willow hedge bordering the footjDath to South Hinksey, only just 

 outside the city of Oxford. Here for about 200 yards it could be seen in profusion, 

 often five or six together on a single leaf, and the ravages of the beetle were con- 

 spicuous at quite a long distance off. It was accompanied by Phyllodecta vitelline, 

 L., and Crepidodera chloris, Foud., but both of these were in comparatively scanty 

 numbers ; its larva) were also there, but not plentifully. I may add that I had 

 passed the spot about three weeks previously, but had seen nothing of the Plagiodera 

 in any stage, though I had swept the willows with my net. I shall be glad to dis- 

 tribute unset specimens of the beetle to any C'oleopterist wlio may wish for them. —

Tripla.v wnea, iSchall., and T. russica, L., at Gibside. — Early in the morning 

 (about 5.30 a.m.) of July 8tli, I found Triplax xnea, Schall., in some fungi growing 

 on elm in Gibside. Returning with my friend Mr. Wallace on the evening of the 

 22nd, we shook some more fungi, and besides turning out several T. xnea, were 

 lucky enough to come across T. russica, L., an insect hitherto unrecorded from the 

 Northumberland and Durham district. On Saturday, the 24th, I examined this 

 part of Gibside more closely, and soon found an elm overgrown with fungi to a 

 height of about 20 feet, and not far from it a holly also overgrown ; and made some 

 observations, which may prove interesting. 



T. asnea and T. russica occurred in almost equal numbers at the foot of the 

 tree, whilst from a height of over four feet T. xnea had the advantage in numbers, 

 and at a height of over eight feet there were scarcely three examples of T, russica 

 to fifty T, xnea ! What is the reason ?
