ind wings are precisely the same colour as 

 he fore wings, and have a slender crescentic 

 iscoidal spot, but no distinct transverse lines, 

 xcept the slender interrupted marginal line, 

 which is common to all four wings ; the head, 

 thorax, and body are gray, and scarcely at 

 all spotted. 



The CATERPILLAR is thus described by Mr. 

 Crewe, under the name of Eupithecia distinc- 

 tata : " Ilather long and slender, tapering con- 

 siderably towards the head ; the ground colour 

 is dark green ; the central dorsal line, broad, 

 and purplish red; the spiracular line, indis- 

 tinct greenish yellow ; the skin is wrinkled, 

 and the back studded with numerous very 

 short stiff bristly hairs ; down the centre of 

 the belly is a whitish line ; the ventral seg- 

 mental divisions are yellowish." It feeds 

 on the flowers of the wild thyme (Thymus 

 serpyllum.} The CHRYSALIS is yellowish green 

 and olive, and changes on the ground, in a 

 slight earthen cocoon. 



The JIOTH appears on the wing in July and 

 August. It has been taken in Scotland, and 

 is common and generally distributed in Ire- 

 land. (The scientific name is Eupithecia con- 

 Istrictata. ) 

 284. THE CAMPANULA PUG. The fore wings 

 are pale dingy brown, with a clearly defined, 

 oblong, discoidal spot, and scarcely any other 

 distinct markings ; there are a few very in- 

 distinct dark marks between the costal and 

 sub-costal rays, and a few dark dots here and 

 there on the wing-rays, the wing-rays them- 

 selves being evidently darker towards the hind 

 margin, and this dark portion being intersected 

 by a slender white zigzag line, which in some 

 specimens terminates in a small white spot at 

 the anal angle of the wing; on the hind 

 margin, just within the fringe, is a slender 

 interrupted dark line ; the fringe itself is 

 dingy brown, interrupted by a few wedge- 

 shaped white spots, very feebly marked ; the 

 hind wings are slightly paler, with a small 

 discoidal spot, a few dark spots on the wing- 

 rays, and a slender interrupted marginal line ; 

 the head, thorax and body are of the same 

 colour as the fore wings, and indistinctly 

 dotted with darker brown. 



Mr. Crewe thus describes the CATERPILLAR : 

 " Ilather short and stumpy ; the ground colour 

 light ochreous brown ; the central dorsal line 

 very deep brown or black, intersecting and 

 uniting a chain of very strongly defined black 

 or deep brown lozenge-shaped spots, placed in 

 the centre of each segment ; sub-dorsal lines 

 very slender and faint, blackish or deep brown ; 

 head, dingy brown or black; spiracular and 

 central ventral lines, dingy black or brown ; 

 central dorsal spots becoming confluent, and 

 merged in the central line on the anterior and 

 posterior segments ; both spots and ground 

 colour varying considerably in intensity of 

 colouring. The skin is rough and wrinkled, 

 and sprinkled with a few whitish hairs. It 

 feeds upon the unripe seeds and seed-capsules 

 of the nettle-leaved campanula (Campanula 

 tracheliuni). Until nearly full-grown it lives 

 either in the dry corolla-tube, or just at the 

 crown of the capsule. In confinement it will 

 feed upon the garden species of campanula. 

 It is full-fed at the end of August and begin- 

 ning of September. The CHRYSALIS is enclosed 

 in a slight earthen cocoon ; its thorax and 

 wing-cases are golden yellow ; its body red- 

 dish ; the abdominal divisions and tips are 

 red." 



The MOTH appears on the wing in July. 

 The caterpillar has been found by Mr. Crewe, 

 who says: "A few weeks since, whilst 

 walking in a beech wood near Tring, I found 

 a number of caterpillars of some species of 

 Eupithecia unknown to me, feeding on the 

 seed-capsules of Campanula trachelium." Mr. 

 Crewe sent them to Dr. Ereyer, who at once 

 pronounced them to be the species described 

 above. (The scientific name is Eupithecia 

 campanulata.} 



Ob:. Mr. Doubleday seems to have no 

 doubt that this species is the Denotata of 

 Ilubner ; but as this problem can scarcely be 

 solved now, it seems desirable to continue 

 Herrich-Schffiffer's very appropriate name of 

 Campanulata, as there can be no doubt as 

 to the species intended by that eminent 

 lepidopterist. 



28-5. THE NARROW-WINGED PUG. The fore 

 wings are rather elongated, rather narrow, and
