new Species of Histeiidae. 177 



the base, widest behind the anterior angle ; the thorax is 

 deeply cut out to receive the head ; the elytra, the two 

 humeral and six dorsal striae are all complete, the third dorsal 

 is bent in the middle, the fourth is bow-shaped and joined 

 to the sutural at the base, the interstices between the sutural 

 and fourth striae are wide, the elytral surface is densely 

 punctulate and under the microscope each puncture is seen to 

 be joined to others by very fine striae ; the propygidium and 

 pygidium, the punctuation consists of fine points intermixed 

 with larger ones, some of the latter are minutely ocellate ; 

 the prosternum, keel narrow, striae joined anteriorly, parallel 

 at the sides but diverging before the base ; the mesosternum, 

 the marginal stria is bisinuous following the outline of the 

 anterior edge, a second transverse stria is oblique at the sides 

 and forms an angle in the middle ; the metasternum and 

 mesosternum are alike evenly, not closely, punctulate; the 

 first abdominal segment is margined anteriorly and laterally 

 and has large shallow punctures on the anterior border. 



This species is somewhat similar to Phylloscelis Arecha- 

 valetce, Mars., which is, as Herr Schmidt states, a species of 

 Discoscelis.

Homalopygus amnicola, sp. n. 



Oblongo-ovatus, parum convexus, undique punctatus, piceus, nitidus ; 

 an tennis pedibusque rufo-brunneis ; fronte dense subocellafco- 

 punctata ; pronoto utrinque bistriato, stria post capitem ia medio 

 interrupta ; elytris, striis 1-3 posticis abbreviatis, 4 antice cur- 

 vata, suturali basi abbreviata ; propygidio pygidioque distincte 

 punctatis ; prosterno bistriato, striis anticis conjunctis ; meso- 

 sterno, stria integra leviter impressa ; metasterno utrinque 

 bistriato. 



L. 3 mill. 



Oblong-ovate, rather convex, piceous, shining; antennae 

 and legs reddish brown ; the head wholly punctate, punctures 

 large and somewhat ocellate but shallow, obsoletely striate 

 over the eyes ; the thorax punctured, points on the outer 

 bordrrs smaller than those of the head, and they gradually 

 become smaller and fewer nearer the disk, on the disk they 

 are fine and sparse, the sides are bistriate, outer stria well 

 away from the margin, very fine, and bending inwards 

 anteriorly, internal stria also very fine and shortened ante- 

 riorly, interstice widest anteriorly, both striae are rather 

 oblique at their bases, behind the head is a transverse stria 

 interrupted in the middle which appears to be an appendage
