Coleoptera, 101 



This species is very like A, infumatus, Cdz., from Ceylon, but is 

 larger, the thorax is much less closely and more strongly punctured, 

 and the brown on the elytra is much more extended. 



38. Megapenthes andrewsi, Waterh., sp.n. (PL X, Fig. 7.) 



Piceo-flavus, parum nitidus ; capitis vertice thoraceque inf uscatis, 

 elytris fortiter striatis, f usco variegatis, striis confertim sat fortiter 

 punctatis, interstitiis parum convexis, crebre asperato-punctatis. 



Long. 14-17 mm. 



This species is one of those that resemble Agrotis in general 

 iorm, and must be placed near 31. agrotus, Cdz. 



Head convex, very closely and rather coarsely punctured ; dark 

 fuscous, the anterior margin obscure yellow, this colour ascending 

 .a little on each side. Thorax a little longer than broad, convex, 

 rather straight at the sides, very slightly narrowed before the 

 posterior angles, which are very slightly diverging, acute, with the 

 inner carina so near to the outer one that it is scarcely distinguish- 

 able viewed from above. The punctuation is densely and moderately 

 fine. There is an impressed line at the posterior part of the disk. 

 . The fully-coloured specimen has the thorax entirely dark fuscous, 

 except the posterior angles. Scutellum fuscous. Elytra deeply 

 striated, the striae strongly and very closely punctured ; the inter- 

 stices moderately closely and rather strongly asperate-punctate, 

 giving the surface an uneven appearance. The colour is sordid 

 yellow, with a spot on the shoulder, and the suture fuscous, 

 the fuscous colour dilating behind the middle. The under-side 

 fuscous, except the margins of the segments and the presternum. 



Varieties. — (1) Elytra with the dark colour extended at the base, 

 and the dilated portion behind the middle joined to the humeral spot 

 •on the seventh interstice. (2) Thorax with the margins and 

 a median line light brown. (3) Almost entirely pitchy yellow, 

 with a spot on the forehead, two discoidal spots on the thorax, 

 the shoulders and suture of the elytra rather darker. 



Taken in September and October, December and January, at 

 Plying Fish Cove.

 €eylon, found on the north coast in December, 1897, and March, 

 1898.
