THE GROUP OF MOLLIS. 71 



Nematus amliguus, Thorns., Opus., 624, 22 ; Hym. Sc., i, 109, 



33; Andre, Species, i, 148 ; Cat., 

 26, 211. 



Head much narrower than the thorax, shining, punctured, the face 

 below the antennae whitish-testaceous. Antennas bare, black, thin, 

 decreasing very perceptibly in thickness towards the apex, the third 

 joint apparently longer than the fourth ; in length the antennae are 

 longer than half the body, if not longer-than the abdomen. Thorax 

 black, shining, mesonotum very finely punctured, half shining, pro- 

 notum pale testaceous ; the cenchri are scarcely visible. Legs white 

 with a testaceous tinge, the femora with a broad black line on the 

 upper side, beneath with a black or fuscous line ; posterior tarsi and 

 apex of tibiae dark fuscous, almost black, the base of the tarsi being 

 paler, posterior tarsi equal to, if not longer than, the tibiae. Wings 

 scarcely hyaline, having a fuscous tinge, especially at the apex, the 

 costa and stigma testaceous ; the first transverse cubital nervure 

 very faint ; second recurrent received slightly in front of the second 

 transverse cubital ; the second cubital cellule has a horny point in the 

 centre ; the third is small, nearly square. Abdomen black, broader 

 at the base than the thorax, the apex bluntly pointed and pilose; 

 the saw scarcely projects, the external part surrounding it is testaceous, 

 and the posterior part of the ventral surface is of the same colour. 



The $ is smaller, and the antennae are thicker, the orbits are broadly 

 marked with testaceous, and there is a broad testaceous splash on the 

 pleurae ; the anal segment above and the posterior half of the ventral 

 surface are of the same colour. Also the posterior tibiae have more 

 than the apical half black ; the antennae are quite black. 



Length 2 2 lines. 



Ab. a. $ pleurae without a testaceous splash. 



b. <? femora not lined with black. 



According to Hartig the larvas feed on the red pine 

 and are green. It does not appear to be very common. 

 I find it on the larch near Glasgow in May. Mr. Dale 

 takes it in Dorsetshire. 



Continental distribution : Sweden, Germany. 



IV. THE GROUP OF MOLLIS. 



Body short, thick-set; vertex thick, strongly punctured ; 

 mesonotum finely punctured, pleura? coarsely punctured, 

 opaque or semi-opaque. Black, apex of abdomen white, 

 or testaceous, pronotum usually lined with white ; legs 

 white or pale testaceous, the base and more or less of 

 femora black. Antennce short, seldom longer than 

 abdomen and thorax, black, very rarely brownish beneath.
