UHLER ON INSECTS. 395 



Perhaps, when a fuller series of these small species has been amassed, 

 it will be possible to recognize this form. 



Nothing short of actual examination of the type will enable us to know 

 precisely to what genus this insect belongs. 'As all the minute forms 

 thus far collected, which approach the Characters given above, pertain 

 to the genus 3Ielana3thus, we infer that this one will prove no exception 

 to the general rule. 



LoBONOTUS, new genus. 



Elongate oval, but greatly widened in front, and with the head very 

 longj'narrow, and almost triangular. Head much longer than wide, tri- 

 angularly rounded in front, the margin barely reflexed, the lateral lobes 

 not depressed, but slanting toward the outer margin, as in many of the 

 Pachycoriclw ; tylus narrow, long, raised a little above the lateral lobes, 

 and forming the apex of the head ; the submargin destitute of spines, 

 but probably bristly (in perfect specimens); eyes almost inclosed by the 

 protracted front angles of t"he pronotum . Eostrum very long and slender, 

 the bucculre nearly as long as the throat, inclosing the basal joint, and 

 obliquely widening posteriorly ; the basal joint shortest; second joint 

 slender, a very little compressed, very long, but shorter than the 

 third ; the third very long, slender, much longer than the second ; 

 fourth very slender, a little shorter than the second. Antennae mod- 

 erately long, slender; the basal joint stout, not reaching the apex of 

 the head ; second joint slender, longer than the third; third a very little 

 stouter, and becoming thicker toward the tip. Pronotum much wider 

 anteriorly than at base, the anterior margin very deeply sinuated to re- 

 ceive the head, the sides anteriorly forming long and wide lobes, the 

 outer margins of which curve bluntly toward the head ; the transverse 

 line broad and shallow ; the lateral margins bald, the edge slenderly 

 recurved ; posterior margin subtruncated. Prosterual groove deep, with 

 steep sides, the marginal flaps arched, but not very broad. Anterior 

 tibire very moderately depressed, and armed on the edge with but very few 

 spines. Ostiolar scale placed far out on the episternum, near its outer 

 margin, broad, rounded on the outer margin, acute at the inner end, and 

 with the osteole placed at that point. Scutellum quite long, acute, not 

 sinuated next the tip. Corium long and narrow, the costal margin a 

 very little curved, the edge destitute of setigerous pits; membrane 

 short, narrow, and with few nervures. 



L. anthracinus, new sp. 



Deep black, shining, a little tinged with rufous on the hemelytra ; head 

 long, triangularly rounded, sloping in front and on the sides, closely, rather 

 coarsely punctate, the base strongly convex, destitute of punctures ; ocelli 

 small, placed near the eyes aud behind the line of their base; eyes large, 

 brown, almost inclosed by the prominent angles of the pronotum. Eos- 

 trum reaching beyond the basal seguients of the venter ; ocherous, sleu-
