12 Mr. 0. E. Janson on new Coleoptera 



broadly rounded and margined at the sides, basal angles 

 rounded and leaving the epimera largely exposed ; basal lobe 

 large, broadly rounded and slightly emarginate at its apex, 

 sparsely punctured on tlie disk and much more coarsely so 

 towards the sides ; besides this punctuation the whole surface 

 when examined under a lens is seen to be very densely and 

 minutely punctured. Elytra narrowed behind and conjointly 

 rounded at the apex, the apical sutural angles in some 

 specimens a little rounded, the disk of each with six deep 

 iurrows bearing chain-like rows of coarse semicircular punc- 

 tures, the interstices very convex and smooth, the sides with 

 three rows of very coarse punctures merging into a coarse 

 transverse strigosity towards the apex. Pygidium transverse, 

 depressed, and coarsely strigose, the underside slightly 

 impressed in the centre in the male, in the female rather 

 more obtuse at the apex and with a large deep central 

 impression on the underside. Beneath coarsely strigose and 

 punctured at the sides ; mesosternal process very large, 

 obliquely divergent, slightly curved and almost vertical 

 towards the apex, which is a little compressed and obtuse ; 

 in some specimens there is a more or less distinct tooth or 

 keel on the inner edge near the apex. Legs short, femora 

 strigose and lightly fringed with short black hairs ; anterior 

 tibise with two lateral teeth, which are more or less obsolete 

 in the male, but large and very acute in the female. 



I received a specimen of this remarkable and distinct 

 insect some years back from Mr. Anthony, but considered it 

 inadvisable to describe it as new upon a single example. 

 Messrs. Meek and Pratt have since met with it sparingly. 

 The strongly arched body, ovate form, deeply sulcate elytra, 

 short legs, &c. will readily distinguish it from Lomaptera. 

 In one female specimen the pygidium is only slightly 

 impressed, as in the male. 



Lomaptera Pratti, sp. n. 



Yiridis, nitida, capite subtus, coxis femoribusque anterioribiis 



nifescentibus et rufo pilosis ; prothorace lateribus punctatis ;

loevi, in apice productis. 

 Long. 33-36 mm. 

 S . Pygidio subter medio subplano, abdomine sulcato, tibiis auticis 



muticis.
