Insects injurious to the Cotton Plant. 161 



a powerful and offensive smell will be perceived, very similar to 

 that given out under similar circumstances by its European and 

 more domestic namesake." — Tropical Agriculturist, p. 24. 



" There are, moreover, red and black bugs, which sometimes 

 suck the seeds of the cotton plant at the period when the capsules 

 open. When seeds so gnawed get accidentally between the rollers 

 of the gin, they are crushed flat, and cause the wool to be soiled 

 with the animal impurities of the bug." — Ure, loc. cit. p. 131. 



Apate monachus, of Guiana. — Dr. Ure observes, " this species 

 of Scarabe, the Apate monachus, is a third enemy of the cotton 

 plant. The larva of this insect begins its attack by boring a hole 

 in the green bark of the cotton tree ; it penetrates into the alba- 

 mum, eats it with a revolving motion under the bark, and proceeds 

 then to the wood and pith ; the branches thus attacked dry up and 

 perish." — Ure, loc. cit. p. 130. 



This insect may be identical with the boll or bore worm of the 

 planters, which Mr. Turner, in a communication to Dr. Royle, 

 supposes to be the larva of a Coleopterous insect, probably a 

 Curculio. 



Referring now to the species, of which there is more positive 

 information to be obtained, I will place them in two divisions ; 

 the first containing those which have already been described, 

 and the second such only as are for the first time brought for- 

 ward as injurious to the cotton plant. In the first division may 

 be mentioned the smeared or cotton moth, L'halcena oblinita of 

 Abbot and Smith's insects of Georgia, figured on plate 94 of that 

 work, and shortly described at page 187, loc. cit. in the following 

 terms, " Ph. noctua, spirilinquis cristata, alis lanceolatis, ccenis 

 punctis nigris marginem versus effluentibus." This, more fully 

 described from the figure, has the fore wings above pale blueish 

 ash grey, covered with indistinct irregularly shaped darkish spot- 

 like markings on the disk, and a row of more distinct round spots 

 of the same colour parallel to the exterior margin ; the hind 

 wings white, with the nervures yellowish, and with a row of black 

 marginal spots. The head and thorax are of the same ash grey 

 as the fore wings, and the abdomen is yellowish white, with the 

 last four or five apical joints tinged with ash grey. The cater- 

 pillar is black, with a broad irregular lateral yellow band on each 

 side, and the joints of the body transversely margined with the 

 same colour ; the joints are marked above with red spots and
