STRONGYLOCEPHAiiUS AGRESTIS. ^ 



vertical point. Pronotum, taken with the sciitelhim, 

 nearly twice the length of the head ; striated trans- 

 versely. Elytron coriaceous, rather short, and without 

 a limbus. Wings as in Acocephalus, the next genus. 

 Hind legs spined on the outer, and finely cihated on 

 the inner, sides. First tarsal joint rather longer than 

 the other two taken together. Genitalia of the 

 males complex, the pygofer ending with two pairs of, 

 or four, unequal projecting processes. 



Only two species hitherto have been recorded as 

 British.

Male. Variable both in colour and size. Some 

 specimens are very dark, others rufous-yellow, and 

 others bright and mottled with brown spots. Head 

 gibbous, ochreous-brown, with the ocelli (or their 

 representatives) near to the anterior vertex. Trans- 

 verse striations in the head and pronotum obvious. 

 Scutellum almost immaculate. Elytra rather longer 

 than the abdomen, with brown bars and spots chiefly 

 disposed along the nervures. Costa with twelve or 

 more dark spots. Legs pale ; the front pair banded 

 with black. Anal nerves on the wings stouter than 

 the rest. Head in profile obtuse, and showing a sharp 

 ridge. Pygofer with two pairs of cornua and a 

 ciliated Cauda. Free portion of the penis subcylin- 

 drical, and barbed at the apex (Edwards). 



Female. Greyish yellow, and larger than the male. 

 The dark blotchings on the elytron much reduced in 

 number, and sometimes wanting.
