This insect belongs to the section in which are M. scapularis, 

 quadrimaculata, dumetorum, lupuli, &c. In colour it some- 

 what resembles M. quadrimaculata ; but the bladder-like form 

 into which the overlapped side margins are produced posteriorly 

 will be found sufficient to separate it from every other known 

 species. 



There appears to be only one example in the collection. 



Monantkia Fieberi. 



Slightly dusky cinnamon-brown, darker across the elevated 

 posterior portion of the overlapped sides of the pronotum, and 

 also in that portion of the elytra posterior to the cells ; anterior 

 margin of the elytra with two rows of meshes throughout. 



Head black. Grown with five pale brownish-yellow spines 

 placed as follows, viz. a short one in the centre in front, 

 another on either side of the last (approximating and appear- 

 ing to form but one between the antenna?), and one along the 

 inner margin of each eye, its apex curving round until it 

 touches the base of the anterior pair. Antennae pale brown ; 

 first, second, base of the third, and fourth joint entirely darker. 

 Eyes black. 



Thorax. — Pronotum, sides at the base for a very short 

 distance straight, then slightly convex towards the hinder 

 angles ; hood very small, anterior margin almost straight ; 

 the overlapped side margins swelled up posteriorly, viewed 

 from above united and enclosing the middle keel, from the side 

 somewhat semiovate, flattened above ; side keels of the scu- 

 tellar process brown at the base, slightly diverging posteriorly. 

 Elytra, sides gradually but gently rounded to beyond the 

 middle, at which last they are widest, then sinuate to the broadly 

 rounded apex ; marginal field with two rows of transparent 

 meshes, becoming larger beyond the middle, in which last 

 some of the reticulation is dark brown and forms almost a 

 patch ; base of three or four of the reticulations in the sinuate 

 portion next the anterior margin with a brown spot ; round 

 the apex dark brown. Legs brown : tibice pale brownish 

 yellow : tarsi pale brownish yellow, third joint brown.

This insect also belongs to the same section as M. monstrosa, 

 from which, however, it is easily separated by the difference 

 in form of the overlapped side margins, which in M. Fieberi 

 unite posteriorly and enclose the middle keel of the pronotum 

 — a character which will also distinguish it from any other in
