took the perfect insect on the wing. The length of the female is 

 5 lines, and of the male 4 lines. They are both of a dark bronze 

 colour, the head and thorax thickly covered with yellowish brown 

 hairs. Antennae black, six -jointed, the last three joints forming the 

 club ; they are a little longer in the male than in the female. As the 

 form of these antennae is somewhat different from that of the other 

 species of this genus, I have given, at fig. 7, an enlarged represent- 

 ation of a male and female antenna. The compound eyes approach 

 much nearer to each other on the crown of the head in the male than 

 in the female. The abdomen is bronze-coloured, and covered with a 

 short, shining, silky, procumbent pubescence ; in the male the fourth, 

 fifth and sixth segments have a black velvety spot in the centre (fig. 6). 

 The legs are light yellow, having the coxae and femora bronze. The 

 coxiE and femora are covered with long soft black hairs ; the tibiae are 

 armed with two spines; on the under side of each joint of the tarsi, 

 except the last, is found an oblong sucker with a soft margin, which 

 I have represented, enlarged, at fig. 11 ; the wings are yellowish, with 

 a fuscous costal nervure ; stigma brown, and a brown stripe running 

 obliquely downwards from the costal nervure, and thence forward 

 again to the stigma ; behind this is a smoke-coloured spot. This 

 marking is less distinct in the female : see fig. 5, and for the neuration 

 of the wing fig. 12. 



The perfect insects were very sluggish, and when in the shade 

 remained motionless ; on being brought into the sunshine they flew 

 backwards and forwards with a heavy flight, making a humming noise. 

 I opened a female for the purpose of examining the saw, and found 

 that in this species its form is much the same as in the other known 

 Cimbices, only somewhat less curved at the extremity (fig. 8). The 

 edge of the saw was distinctly furnished with implanted dentate lobes, 

 which projected considerably (fig. 9). 



From the larvae of these saw-flies were produced both sexes of 

 Exetastes Cimbicis, V. VolL, a new species, of which 1 have given a 

 description in the ' Bouwstoff"en voor eene Fauna van Nederland' 

 (Materials for a Fauna of the Netherlands), ii. 281. 



I take this opportunity of stating that a specimen of the very nearly 

 allied Abia fasciala, F., has been added to the collection of the Nelher- 

 land Entomological Society, subsequently to the publication of 

 the Catalogue of Netherland Hymenopterous Insects, and of the 

 occurrence of which in this country no mention is made in the 

 * Bouwstoff'en voor eene Fauna van Nederland.' The specimen in 

 question was presented by Mr. Lodeesen, who, however, could not
