appear to be numerous feeble ridges extending parallel with 

 the median carina. The elytra at first appear to have very- 

 wide striae and narrow interstices, but this is not the case, as 

 the striae are really very narrow (this is very noticeable pos- 

 teriorly) and supplied with irregular punctures; these are 

 rather large on the basal half, and each appears to be supplied 

 with granules that really belong to the interstices. The inter- 

 stices are much wider than the striae, and each, except the 

 suture, is more or less distinctly ridged along the middle, and 

 with a conspicuous row of punctures on each side of the ridge. 

 The dentition of the four hind tibiae is suggestive of 

 P sepholacipus . 



TYRTiEOSUS BIFOVEICEPS, n. Sp. 



Black; antennae and tarsi reddish. 



Head with coarse and somewhat irregular punctures in 

 front; a rather deep and somewhat pyriform impression 

 behind each eye. Eyes separated the width of rostrum at 

 extreme base. Rostrum rather long and thin, notched on 

 each side of base; basal half with rather coarse punctures, 

 subseriately arranged, and leaving a median carina, which is 

 distinct only at extreme base, apical half with small 

 punctures, but absent along middle. Prothorax and elytra 

 with outlines much as in preceding species; metasternum, 

 abdomen, and femora much the same. All tibiae dilated to 

 apex, the four hind ones not bidentate at outer apex. 

 Length, 9 mm.

The types of this and the preceding species are uniques; 

 their shape and general appearance are much the same, and 

 the sculpture of the present species might be regarded as 

 simply an exaggeration of that of the preceding ; but the four 

 hind tibiae are so different, inter se, that I have not hesitated 

 to describe them as distinct. The depression behind each eye 

 is much as in the preceding species, but is rather less sharply 

 defined; the one behind the right eye is somewhat obscured 

 by an oblique (but not shining) ridge, but the other is simple. 

 The type is certainly somewhat abraded, but the clothing that 

 is left consists of more or less ochreous setae, and was 

 apparently very similar to that of the preceding species. The 

 prothoracic punctures are rather larger than in that species, 

 and with a less tendency to become confluent. The elytra 

 about the basal half appear to have striae much wider than 

 the interstices, owing to the punctures there (although large) 

 not being sharply defined, but on the apical half of the elytra 

 the striation is deep, narrow, and sharply defined, the inter- 

 stices much wider than the striae, and, except the suture, each
