THAMNOTETTIX SUBFUSCULA. 81 



Very like the preceding insect, but darker, and more 

 covered with brown punctures. 



Male. Head pointed, with a brown inter-ocular 

 streak, which is sometimes disjoined. Two black 

 punctures near to the anterior border of the pronotum. 

 Frons yellow and black. Pronotum semilunar in form, 

 marked with numerous small dashes and spots, as also 

 is the scutellum. Abdomen brown, with a large 

 opening on the pygofer showing a minute Cauda. 

 Legs streaked. Elytra long and rounded at the apices, 

 with yellow veinings, indicating the fuscous brown 

 areas. Wings large and grey. The sutural nervures 

 forked and very stout. 



The female is paler and less highly ornamented than 

 the male. The last ventral segment emarginate, and 

 provided with a medial central tooth. 



Some examples are very dark in colour, and then the 

 pale neurations on the elytra become almost obsolete.
