262 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [May 8, 



My specimen from Singapore has testaceous antennse, except the 

 two basal joints. Mr. Lamb's specimen has black antennae, except 

 the underside of the third joint, which is of a cobalt blue. M. J. 

 Thomson does not mention the antennas at all. 



Glenea manto. (PI. XXVIII. fig. 7.) 



G. nigra; prothoraee dimidio basalt, elytrisque plaga media 

 magna communi et macula apicali pube crassa albida (yel 

 ochrucea), indutis. 



Black, with a short black pubescence, mixed with a few setulous 

 hairs ; the posterior half, or rather more, of the prothorax, a large 

 median patch common to both elytra, and a spot at the apex of each 

 densely coveted with a very coarse whitish or ochraceous pubescence ; 

 head with two white stripes in front ; prothorax slightly rounded at 

 the sides, scarcely contracted behind ; scutellum rounded, black ; 

 elytra tapering posteriorly, the pubescence nearly hiding the punc- 

 tures in fresh specimens, the external mucro at the apex of moderate 

 length ; body beneath and legs testaceous, sparsely pubescent ; an- 

 tennse brownish. Length 5-6 lines. 



Similar in the disposition of its colours to Glenea funerula, 

 Thorns.* ; but the pubescence {inter alia) of that species, so far as 

 the white portion of it is concerned, is exceedingly short and dense, 

 so as to look like a sort of incrustation. The white colour, how- 

 ever, varies ; in my Sarawak specimens it is of a pure ochreous tint, 

 in Mr. Lamb's specimen it is snowy white. 



Glenea anthyllis. (PI. XXVIII. fig. 6.) 



G. corpore pube densissima sulphurea, nigro maculata induto ; 

 elytris ante medium maculis duabus, apicem versus fasciis 

 duabus latis (aliquando ad suturam interruptis) nigris. 



Everywhere covered, except the legs and antennae, with a dense 

 bright sulphur-yellow pubescence spotted with black ; head with the 

 vertex and stripe between the eyes black ; prothorax with four 

 spots, or the two anterior united and forming a band ; elytra rather 

 short, the apex nearly directly truncate, the outer angle suddenly 

 produced into a mucro, a large round spot anteriorly on each, pos- 

 teriorly two bands, one nearly apical, either united or one or the 

 other more or less interrupted at the suture ; body beneath entirely 

 yellow; legs pale testaceous ; antennse black. Length 6 lines. 



Near G. sulphurella, AVh., which has, however, many-spotted 

 elytra without apical bands. Found also in Sumatra and Borneo. 

 Another Glenea in the collection is closely allied to G. fricator, 

 Dalm., but with a yellowish head, not black. The whole of the 

 genus Glenea will require more ample materials than any we now 

 possess before we can be sure of the veritable species. What is 

 generally considered to be conclusive evidence is not wanting to 

 show that a form so entirely different as G. grisea is but the male 



* Stibara funerula, Arch. Ent. i. p. 141. At least if I am right in my deter- 

 mination of it.
