184 Mr. E. MacLachlan's Monograph of 



of two disconnected spots ; the costal veinlets and the 

 sub-costa and radius blackish fuscous, with short pale in- 

 terruptions ; the rest of the longitudinal veins pale, with 

 closely placed blackish points ; fuscous blotches, more 

 or less distinct, along the radius ; three sectors ; gradate 

 veinlets blackish, six to seven in the outer series, six in 

 the inner, and others at the base ; pterostigma reddish- 

 brown : posterior pair paler, whitish, very iridescent ; 

 pterostigma long, dark reddisk-brown ; costal veinlets 

 and radius, and sub-costa wholly blackish ; the other 

 longitudinal veins blackish in part, othermse pale ; gra- 

 date veinlets mostly blackish. 



Length of body 2j-2f lines; expanse of wings 7-8 

 lines. 



I have not seen males that I can confidently refer to 

 this species. 



There are three or four specimens in the British 

 Museum, all similar, and one of them bears the label 

 " pini ; " these are probably those from Scotland referred 

 to by Stephens ; all the other examples I refer to limha- 

 tus, and these are probably from Hertford. Stephens' 

 description agrees with Leach's examples, but not with 

 his own. It is also in Mr. Dale's collection, and may be 

 not uncommon. 



It is possibly identical with punctaius of Gozsy, 

 of which I have certified Austrian types; these latter, 

 though variable, do not show the transverse fascias with 

 such distinctness, and are, perhaps, slightly larger ; but 

 local influences may account for these slight differences. 



10. Hemeeobius atrifeons, n. s. 



Bright yellow, the sides of the head and the three 

 divisions of the thorax broadly shining fuscous, leaving 

 the yellow ground colour as a pale median line ; face 

 shining black ; antennce yellow, with narrow dark annu- 

 lations. 



Abdomen dark fuscous, with the margins of the seg- 

 ments, and a line on each side, yellow ; pubescence brown, 

 or golden-brown. In the ? the appendices are similar 

 to those of H. limhatus, but dark fuscous, with a yellow 

 callosity at the base ; the upper prong of the fork is pro- 

 bably slightly shorter, and thus equal with the lower.
