tudinally, whereas in all the others it is more or less convex longitu- 

 dinally, the costae of the sulcature also are much shorter than in its 

 allies. Antilope can then he separated off by the concavity of the 

 metathorax above the insertion of the body, which is distinctly 

 shining, whereas in the others it is quite dull. We are then left with 

 ^-marginafus, i^-fasciatus, pm'ietiniis, and pictus. Trifasciatus may be 

 known by its long thorax, the mesothorax being longer than wide 

 across the tegulae ; ^-viarginatus differs from the other two in having 

 only three abdominal bands ; finally, parietinus differs from pictus in 

 having the 1st segment of the body narrower, and its band largely and 

 suddenly dilated on the sides, while in pictus the bands are all linear. 



The third section {Symmorphus) has three species : crassicornis 

 may be known by its larger size, smooth and almost impunctate sides 

 of the mesothorax ; gracilis has many abdominal bands, the thorax 

 truncate in front, and its angles mucronate ; sinuatus has only three 

 abdominal bands, the thorax rounded in front, and the angles not 

 mucronate. 



Mr. Bridgman first called my attention to parietinus, and remarks 

 that there is a first-rate figure of it in Curtis's British Entomology ; 

 there is no doubt, I think, that all the species are good and distinct, 

 they only want a little careful examination.

A NEW EUDROMUS, AND THREE NEW SPECIES OF LEPTURIDM 

 FROM MADAGASCAR. 



BT H. W. BATES, F.L.S. 



In the few remarks I published in the January number of this 

 magazine on the remarkable carabideous genus Eudromus, I alluded to 

 the probability that more species yet remained to be discovered on the 

 highlands of central Madagascar. It so happens that the next col- 

 lection arriving in London from that island contained a strikingly 

 distinct and beautiful new species of this genus, which I take this 

 early opportunity of describing. 



In the same small collection, and in a previous one of similar 

 character, the extraordinary Lepturidw of Madagascar were well 

 represented ; there being, besides Sagridola maculosa (Gruer.) and 

 Logisticus rostratus (C. 0. Waterhouse), three new species of large 

 size, one a new genus, the descriptions of which are here added.
