56 Mr. G. Lewis on 



Hister pyxidatus, Lew. Ann. & Mag. Nat. Hist. iii. p. 282 

 (1889), n. syn. 



Ulster phar-aonis, Sch. Ent. Nachr. xv. p. 90 (1889), n. syn. 

 = Sister montanus, Mars. Mon. p. 413, p. 10, f. 33 (1857). 



I have the type of the first named and a cotype from the 

 author of the second. Marseul's description and figure of 

 montanus are very good, but both Schmidt and myself over- 

 looked it. 



Hister belti, Lewis, n. n. 

 Hister castaneus, Lew. Ann. & Mag. Nat. Hist. xv. p. 465 (1885). 



This species requires a new name, because Hololepta 

 castaneus, Menetr., 1832, apparently is an older name for 

 Hister smymceus, Mars., 1854. I have now named it after the 

 captor, Mr. Thomas Belt, whose book ' The Naturalist in 

 Nicaragua* is well known. 



Peranus bimacuJatus, Linn. 



Hister bimaculatus, L., differs from Hister corvinus, Germ., 

 which is the type of Thomson's genus Atholus, by the 

 characters which distinguish Peranus. 



Pachycrarus hyalus, sp. n. 



Oblongo-ovatus, parum convexus, virescens, nitidus, pedibus obscure 

 brunneo-rufis ; fronte concava, tenuiter punctulata ; pronoto 

 undique punctato, stria marginali antice interrupta ; elytris striis 

 5 et subhumerali dimidiatis, l-4suturalique integris ; propygidio

 tibiis anticis 5-dentatis, dente apicali bifido. 



L. 4 mill. 



Oblong oval, rather convex, elytra brassy green, thorax 

 faintly coppery ; the head, forehead, and clypeus concave 

 without a transverse stria, surface finely punctulate ; the 

 thorax, marginal stria anteriorly fine and slightly interrupted 

 behind the head, surface clearly and evenly punctured ; the 

 elytra, stria?, subhumeral and fifth dimidiate, 1-4 complete, 

 sutural almost touches the base and it has an adjacent basal 

 puncture ; the propygidium is wholly punctured like the 

 thorax ; the pygidium has smaller points and is somewhat 

 smooth at the apex ; the prosternum is bistriate, strife meeting 

 anteriorly and slightly widen out to the base ; the meso- 

 sternum is rather sharply acuminate and marginate; the 

 anterior tibiaj are 5-dentate, apical tooth bifid.
