One specimen. Smaller than E. 2>eruvian us ; the prothorax rufous, 

 with two black spots, the sides more rapidly convergent from the base, 

 and the basal f oveae much shallower ; the elytra more finely punctate, 

 witliout trace of seriate punctures on tlie disc ; the head smaller. The 

 finely, confusedly punctate, incompletely striato-punctate elytra, the less 

 rounded sides of the prothorax, and the very prominent mesosternal keel, 

 separate the present species from the similarly coloured Central 

 American E. margitiatvs Champ. These characters indicate that the 

 Brazilian insect referred by Seidlitz to E. marginatus must have been 

 wrongly identified, and it possibly belongs here. 



Synstrophtjs. 



Synstroj^hus Seidlitz, Naturg. Ins. Deutschl., v, 2, pp. 438, 442 

 (1898). 



Seidlitz gives Eiidrophus macrophfhahnus Reitt., from Jaj^an, as 

 the type of tliis genus, and correctly states that the N. American 

 E. repandus Horn must be included in it. An insect from Burma in 

 the British Museum is congeneric with them, the principal characters 

 being the non-crenulate posterior tibiae, the fusion of the episterna and 

 epimera of the prothorax, and the large, contiguous eyes. In E. 

 tnacrophthabmis and E. rejKindus the prosternal process is unemarg- 

 inate at the tip, whereas in the new species now added the process is 

 triangularly notched, showing that this character, used to separate 

 EustroyMnus from Eiistrnphujjsis, cannot always be relied upon for 

 generic diagnosis. Eustrophus roUei Pic, from Formosa, is said to be 

 related to E. macrophthalmus, and it therefore probably belongs here. 



1. — Syiidrophiis ater, n. sp. 



Elont^ate oval, acuminate posteriorly, moderately shining ; black above and 

 beneath, thickly pubescent, the hairs on the prothorax reddish-brown, those on 

 the rest of the surface much darker. Head small ; eyes contiguous ; antennae 

 rather short, joints 5-10 stout, triangular. Prothorax arcuately narrowed from 

 the base, closely, very finely punctate, the almost obsolete basal foveae bearing 

 three or four coarser punctures, which are longitudinally conflvient in one 

 example. Elytra long, rapidly narrowed from the Ijase, finely striato-punctate, 

 the interstices flat, closely punctate, the epipleura slightly hollowed anteriorly. 

 Beneath sparsely, finely, the abdomen densely, punctate. Prosternal process 

 rather broad, omarginate at tip. Mesosternal keel very prominent. Length 

 8^-8|, breadth 3J-3J mm.
