5G Observations on various Insects 



is connected with the trefoils ; but as they are not known to affect 

 the crops, we need only refer to them here. 



13. Gelechia Anthyllidella. Hubners TinecE, fig-. 330. 



The caterpillars feed in April and June on the united leaves 

 of the red and white clovers, Antliyllis vulneraria and Onobryclds 

 sativa : the moths hatch in May and August. Another species is

p. 301. 



In spring and autumn the caterpillars are found in little cases 

 attached to the leaves of Lotus corniculatus, and the moths from 

 them make their appearance in June and July. A third species 

 of these little moths is

p. 295. 



The moths being always found in clover-fields, it is presumed 

 that the caterpillars feed upon the leaves, but at present tliey are 

 unknown. 



On the 12th of February, 1841, Professor Henslow sent me 

 some tares ; at the base of the calyx were 2, 3, or 4 little maggots, 

 which had eaten out the germen, but sometimes without touching 

 the base of the pod or the corolla (fig. 22). They were of a pale 

 vellowish-white, with orange, forming an interrupted line down 

 each side of the back, and spreading towards the apex, which 

 was slit; they were granulated or punctured, with a pair of short 

 rigid bristles on each side of the head (fig. 23 ; 24 the same 

 magnified). They were probably the larvae of some Apion, but 

 they all died, owing to the tares being kept too dry. 



On the 12th of July, 1848, 1 examined about an acre of vetches 

 in a field, three-quarters of which had the flower-heads dis- 

 torted, and could produce very little or no seed. The leaflets in 

 many instances were blotched with brown, and on opening the 

 heads I found numbers of maggots concealed in and between the 

 calyces ; they ate into the base, and were visible only on forcing 

 open the calyces : some of the heads were advancing to flower, 

 and in the withered flowers were one or two of these maggots, 

 which had entirely consumed the incipient pod, VVliether these 

 were the maggots or not of Apion jwmoncc I am unable to say. 

 At the same time there were also many ochreous apterous larvae 

 of some Thrips, and likewise little lead- coloured transparent ones 

 running amongst the heads of flowers, which were the larvae of a 

 Nitidula, or some other little beetle. These were accompanied
