NEMATUS CAPRE./E. 101 



/. As in c, but with only a narrow yellow band over 

 the eyes. 



Male aberrations : 



g. Entirely black except the anal parts ; the 

 tegulse black, the knees, and the basal three fourths of 

 the tibiae pale white. 



h. The legs pale luteous, black at the base, the 

 three apical segments of abdomen and a dull yellow 

 ring round the eyes luteous. The apical joints of the 

 tarsi fuscous ; the mouth and tegulae black. The 

 stigma luteous. This was bred along with the ? 

 aberration e. 



i. As in h, but tegulae luteous, the mouth white; 

 on the abdomen the anal parts only are yellow. 



j. The labrum, knees, tibiae, and tarsi whitish, 

 the rest of the body black. 



Jc. As in i, but the abdomen luteous except the two 

 basal abdominal segments above. 



This most variable species has a considerable resem- 

 blance to hcemorrhoidalis, but they are easily separated 

 by noticing that the head in caprece is considerably 

 dilated behind the eyes, that the third joint of the 

 antennas is curved on the underside and is shorter than 

 the fourth ; the ground colour is different, it being a 

 reddish testaceous yellow, and it shows none of the 

 livid white colour so noticeable in hcemorrhoidalis, 

 while the stigma is whiter. 



In addition to the colour varieties enumerated above, 

 it may further be pointed out that the position of the 

 second recurrent nervure varies, it being sometimes 

 placed almost in the middle of the second cubital 

 cellule, while oftener it is almost joined to the second 

 cubital nervure. The antennae again are apparently 

 longer and thinner in some females than in others, and 

 the curvature in the third joint is scarcely apparent in 

 some examples, although very well marked in most 

 specimens. Many males, too, have the antennae and 

 pleurae more pilose than in others. The size of the 

 third cubital cellule is subject to variation ; in a few
