160 Mr. G. Lewis on 



The oblique basal stria or carina on the thorax seems to 

 connect this species with P. jAicicolUs and suhjylicatus, Sch. 

 In P. carinistrius all the striae are more or less caiinate.

Phoxonotus suturalisj sp. n. 



Ovalis, convexus, picens, nitidus ; fronte utrinque marginata; pro- 

 noto stria marginali Integra, tuberculis 4 basi ; elytris sutura 1- 

 tuberculata, stria 4'> 3-tuberculata ; prosterno lato bistriato, striis 

 antice divergentibiis ; mesosterno perspicue punctate, stria ad 

 suturam irregulariter impressa. 



L. 4 mill. 



Oval, convex, piceous, shining; the head striate on either 

 side, surface very finely punctured; the thorax, marginal 

 stria complete, but extremely fine behind the head, with four 

 transversely placed tubercles, the two inner ones being well- 

 marked ; the elytra, humeral striae carinate and complete, 

 1 dorsal apieally shortened and somewhat indistinct at the 

 base, 2-3 basal and not well-defined, 4 represented by three 

 tubercles, the other stria3 are wanting, behind the scutelluni 

 there is a sutural tubercle common to both the elytra, surface 

 finely and evenly but not closely punctured ; the pygidia are 

 punctured like the dorsum ; the prosternurn, striae carinate 

 and gradually but widely diverge in front; the mesosternum 

 is marginate anteriorly, clearly but not closely punctured, 

 and the sutural transverse stria is fine and irregularly crenate ; 

 the tibiae resemble those of tuberculatus, Mars. 



The sutural tubercle on the dorsum distinguishes this 

 species from the four others known. P.fri/i, Lew., has a 

 sutural stria at the base of the mesosternum which is evenly 

 and finely crenulate ; lectus, Lew., has this stria faint and 

 very irregular, and in suturalis it is irregular but clearly 

 defined.
