NEMATUS GLUTINOSJJ. 127 



Green, or testaceous-green ; the space enclosing the ocelli, the usual 

 marks on mesonotum, a ring surrounding the cenchri, a small one 

 behind them, and a row of transverse stripes on dorsum of abdomen 

 (becoming narrower towards the apex), black. Antennae somewhat 

 shorter than the body, filiform, black, fuscous beneath, the third joint 

 a little longer than fourth. Head sharply bulging out behind the eyes ; 

 looked at from above, the front projects distinctly from the sur- 

 rounding part, and is furrowed between the antennae; the frontal 

 area is well denned, square at the apex; the antennal fovea is indistinct, 

 but a well-marked furrow comes down on either side of it from the 

 outer side of the frontal area and curves round the base of antennas. 

 The central furrow on vertex is well defined, broad in front, narrow 

 behind. Spurs a little more than one fourth of the length of meta- 

 tarsus, being as long as the cerci. Stigma greenish-white. 



The (^ has the antennae longer than the body, with the third joint 

 shorter than the fourth, the lower part of the body and the sides of 

 abdomen above are rufescent, the upper part black, the thorax entirely 

 so, save an incomplete ring on scutellum, the central portion of which 

 is black. The posterior tarsi are fuscous black ; the stigma fuscous. 



Length 2| 3 lines. 



Very similar to ~N. miliaris, but the front is wider 

 between the antennae, and does not project so much ; 

 antennal fovea less denned, head smaller, cenchri 

 smaller, spurs shorter compared to metatarsus, which 

 is itself shorter compared to the second joint ; abdomen 

 with a broad continuous black band ; the scutellum is 

 marked with fuscous in the centre, and the frontal area 

 is more distinct. 



The larva feeds on alder. It is green, the head of 

 a darker green, especially on the top; a black line 

 goes on the side from the top to near the eyes, and 

 another line runs from the top, half way down the 

 face; mouth brownish; mandibles blackish at the 

 top. The body is covered with tubercles of a darker 

 colour than the body, and generally irregularly- oblong 

 in shape. On the first and last segments they are some- 

 what irregularly arranged, but on the middle segments 

 they are usually in two pairs above, and three in a 

 line below these, while there is a longer, slightly 

 curved, one over the claspers, and one or two smaller 

 tubercles above it. Two curved lines are over the 

 feet, which are glassy white with brown claws. On 

 the back are two white lines ; there is no distinct 

 black line along the sides, beyond a thin white one
