380 Mr. C. O. Waterhouse on new Coleoptera. 
the punctuation of the interstices is fine and sparse. The 
pubescence is very short and rather coarse, and would pro¬ 
bably never be very close. The mesial projection of the pro¬ 
sternum has a deep impressed line all round, the enclosed part 
sparingly and rather strongly punctured ; mesosternum rather 
thickly but obscurely punctured. The epipleura of the elytra 
is very closely, finely, and obscurely punctured. Tarsi long, 
especially the posterior pair. 
The only described species which appears to have long tarsi 
like the present species is M. grande , Thomson, from which 
it differs in having the thorax more transverse, and the epi- 
pleurae of the elytra not smooth.

Monomma abstrusum , sp. n. 
Ovale, leviter convexum, nitidum, piceo-nigrum, brevissime fulvo- 
pubescens; thorace irregulariter subtiliter punctato, angulis 
anticis prominentibus, obtusis; elytris thorace 2-| longioribus, 
sat fortiter striato-punctatis, striis apicem versus evanesceutibus, 
circa scutellum fossato-punctatis ; prosterni projectura vix mar- 
ginata, ltevi; tarsis sat longis.

Rather a short broad species, closely allied to the preceding, 
but much smaller and relatively shorter and more oval. The 
thorax is very distinctly but not very thickly punctured, the 
punctuation unequally distributed. Elytra with lines of 
rather strong punctures, which do not extend to the apex, the 
interstices almost without punctuation ; the rather coarse ful¬ 
vous pubescence is irregularly distributed. The prosternal 
projection has its margins slightly raised, quite smooth and 
shining, as is also the mesosternum. 
This species is closely allied to the preceding, and has long 
posterior tarsi; but it is a much shorter species ; the projec¬ 
tion of the posterior margin of the thorax over the scutelium 
is unusually acute. Scutellum transversely cordiform. The 
punctures of the elytra around the scutellum are large and 
horseshoe-shaped. The prosternal process and the meso¬ 
sternum are smooth.
