This species is considerably smaller than the preceding ; it is 

 usually pitchy black with a more or less cyaneous tinge, antennae 

 and mouth red. Thorax proportionally more dilated and rounded 

 at the sides, and shorter, with the lateral margins less elevated, 

 and the posterior angles more prominent. Elytra distinctly punc- 

 tate-striated, with some larger impressions on the third stria 

 from the suture as in spinibarbis ; legs entirely red. Length 

 3-31 lines. 



It is found in immense profusion in marshy places in spring 

 and autumn. L. Janus is an immature example of this insect, 

 to which also L. indent atus must be referred. 



3. I*, montanus : " c&ruleus, thoracis margine later all ore 

 antennis pedibusque rufis."

" Similar to the preceding (fulvibarbis}, but known at once 

 by its more elongated structure, and especially by the form of 

 the thorax (PL I. f. 5) ; the upper surface is fine blue tinted 

 with greenish on the head and thorax; the head is narrower 

 and the eyes are less prominent than in L. fulvibarbis ; the 

 thorax is narrower, more depressed and elongated, it is divided 

 by an impressed longitudinal line, the disk on each side being 

 smooth, in front of the impression is a triangular space thickly 

 sprinkled with impressed dots and a similar space covered with 

 impressed dots behind, the margin is also punctated and the 

 sides are rufo-ferruginous ; the elytra are blue, with eight striae 

 composed of impressed dots, and in the specimens which I have 

 examined they are destitute of any impressions between the 

 third and fourth strise ; the mouth, antennae and legs are rufo- 

 ferruginous, the latter dusky at the tips of the femora ; beneath 

 pitchy blue, with the pleurae and sides of the abdomen deeply 

 punctate. Length 3| lines/" Mr. Stephens.
