Continental specimens of reputed Bi'itisla insects — such as Aglia Tau, 

 Gluphisia crenata, &c. I had never looked on the box as containing 

 anything of value till I read Mr. Mason's note on Plusia himaculata 

 at p. 1G3 of this volume. I then referred to this box, and there, sure 

 enough, was the missing specimen, along with several other apparently 

 British specimens of curious Plusics. 



I lost no time in communicating my discovery to Dr. Giinther, 

 F.E.S., and hearing from him that the Museum would be glad to re- 

 ceive this box of insects, I took it there and handed it to him on the 

 22nd June. It had been an inmate of this house for 38 years !

MACLEAY. 



by b. g. nevinson, m.a., f z.s. 



Phan. Boucaedi. 



Niger subnitidus. Clypeus einarginatus et valde bidentatus angulis 

 utrinque obtvsis. Thorax omnino grosse punctatus, antice ceneus angulis 

 obtusis, ad basin bi-impressus. Elytra striata interstitiis subconvexis minute 

 punctatis. Corpus subtus rufo-hirtum metasterno punctata medio canalicu- 

 lata, pygidio ceneo crebre functato. TibicB anticce quadridentatce in utroque 

 sexu sine tarsis. 



Mas major. Caput cornu erccto, transverse trituberculato, tuberculo medio 

 vix majore. Thorax abrupte in medio declivis utrinque profunde foveolatus, pro- 

 cessu superiore obtuse quadridenticulato, denticulis lateralibus majoribus sed vix 

 divergentibus. 



Femina. Frons transversim eariuata et trituberculata. Thorax omnino grosse 

 punctatus, antice declivis, apice medio transversim et areuatim carinato, pone 

 carinam leviter depressus. Long., 22 mm. 



Hah. : Nicaragua (Boiicard). 



This interesting species comes close to Ph. Pluto, Har. The 

 clypeal teeth are very long and slender, and the head horn sharply 

 tridentate, the teeth being more approximate than in Pluto. The 

 median process of the thorax is obtusely quadridentate, the exterior 

 teeth being barely produced, instead of, as in Pluto, being strongly 

 divergent. The whole of the thoracic surface, including even the 

 shining declivous portion, and the deep depression on either side of 

 it, is strongly punctured. The stria? of the elytra are broad and 

 opaque, the inter.stices narrow and shining on their summits, and
