258 Mr. G. Lewis on 



Eblisia exortiva, Lew. Ann. Mus. Genova, vi. p. 636 (1888). 



This species appears as an Idister in ray catalogue o£ 

 1905, but as the tarsal grooves are not curved, it is well to 

 place it in Eblisia until further revision of the genus is 

 made. 



Hister quadrimaculatus, L. 



Herr H. Bickhardt has furnished this species with a 

 twentieth name, one suggested by its superficial coloration. 

 Not long since four other names were given on similar 

 trivial characters, and 1 think that the multiplication of 

 names of this kind is much to be deprecated. 



Pachycrcerus baconi, sp. n. 



Oblongiis, parum convexus, niger, nitidus ; fronte punctata, stria 

 Integra ; pronoto stria lateral! antice interrupta ; elytris striis 

 1-3 integris, 4-5 suturalique brevibus, margine apicali punctato ; 

 prosterno angustato bistriato, striis parallelis; mesosteruo stria 

 arcuata ; pygidio vix dense puuctato ; tibiis anticis 5-dentatis. 



L. 2 =-3 mill. 



Oblong, rather convex, black and shining ; the forehead 

 feebly convex, distinctly and somewhat closely punctured, 

 stria complete and rather fine ; the thorax punctured like 

 the head except in the scutellar region where the points are 

 finer, lateral stria rather near the edge and it ceases behind 

 the eye ; the elytra, apical margin punctate, dorsal striae 1-3 

 complete, 4 dimidiate, 5 short not reaching the apex nor the 

 middle of the disc, sutural shortened at the apex and reaching 

 the disc, subhumeral very short and basal ; the propygidium 

 and pygidium are rather closely punctured, the latter is not 

 smooth at the apex ; the prosternum, the keel is narrow and 

 the lateral striae parallel ; the mesosternum is obtusely 

 acuminate anteriorly and the stria arched not marginal; the 

 anterior tibiae are 5-dentate. 



This species is very similar to P. verulamii, Lew. ; it is a 

 little smaller and slightly narrower. Both have a narrow 

 prosternal keel and the mesosternal stria of each is of similar 

 outline. The punctuation of the head, thorax, and pygidium 

 is very distinct in baconi and the thoracic stria is similar in 

 both species, but the lateral margin is widest in verulamii.
