of some Hemipterous Insects. 91 



This differs from the Dryptocephalcs Brullei (^Storthia livida 

 Pertij), aspenda and cydnoides (Storthia) Pcrtij, in having the head 

 only two-lobed ; the eyes are much larger than in D. Brullei. I 

 have given it the subgeneric name of Cephaloplatus. 



A mutilated insect, from the Congo expedition, in some re- 

 spects coming near the description of the JEl'ics lanceolata and 

 hastata of Fabr, and Megarhynchus acanthurus Hope, has the long 

 rostrum o^ Atelocera, but, instead of an oblong second joint to 

 the antenna, has it cylindrical. I describe it under the name of 



JE,Ua f gracilis. 



A. pimctatissima, pallide virescens, capitis margine, thoracis parte 



anticd lincdque suhmarginali abhreviatd nigris. 

 Long. lin. 7, lat. 2^. 

 Hab. Congo, In Mus. Brit. 



Head much acuminated, indistinctly cloven for nearly half its 

 length, beak pale green, four-jointed, reaching to base of hind 

 pair of legs, second joint longest, the fourth black, antennae (mu- 

 tilated). Thorax widest behind, in front with two abbreviated 

 submarginal black lines, and a small smooth space on each side 

 of them, having a black spot on the inner angle. Scutellum 

 somewhat pointed, half the length of abdomen. Hemelylra 

 (membranaceous part) with seven rather straight veins, and indis- 

 tinct ones between them. Abdomen somewhat serrated on the 

 margin, gradually narrowing towards the tip, palest beneath in 

 the middle and on the margin, which has also five black spots. 

 Legs pale yellow, the tibiae slightly ciliated. 



Mlia (^Megarhynchus, Laporte) ccenosa. 



y£7. sordide hrunnea, scutello subtusque palUdioribus, capite Jisso, 

 acuminato, thoracis ^^otrie posticd in spinam validam porrectd ; 

 antennarum apicihus fulvis. 

 Long. lin. 8-81. 

 Hab. Gambia. In Mus. Brit. 



Head cloven, black. Antennae black, five-jointed, first short, 

 second, third and fourth nearly equal, fifth rather longer, fulvous 

 at tip. Thorax in front slightly serrated, punctato-rugose be- 

 neath, with an interrupted lateral palish line. Scutellum rounded 

 at end, pale brown, with three longitudinal rows of unequal ele- 

 vated points. Membranaceous part of hemelytra with black spots 

 on the sides of the seven rather straight nerves. 



This insect is not uncommon in collections from the Gambia, 

 and may prove a dark coloured variety of Megarhynchus mar- 

 ginellus, Hope.
