look for the parasites on the fruit fallen under the trees ; I found 

 many articulates, which were classified by specialists of the Washing- 

 ton Bureau and they are the following ones : 



A larva of Elateridae, belonging to Melanotus or some allied genus. 

 As far as known, the larva? of this genus live underground on the 

 roots of various plants. 



Stelidota geminata, Epuraea labilis. Both belong to the family 

 Nitidulidae, or sap beetles, and are known to feed on decaying fruit 

 and similar substances. 



A Staphylinid beetle of the genus Osorius, the species being in 

 all probability undescribed. This is certainly not injurious to fruit, 

 the species of this genus living in the ground. 



Larva of Anastrepha (Trypeta) ludens Loew. 



A Curculionid larva, probably belonging to the genus Conotrack- 

 elus. 



Species of this genus attack and injure healthy fruit, and an effort 

 should be made, therefore, to breed the perfect beetle. This insect, 

 however, was never found any more as injuring the fruit. 



A Carabid larva belonging to the subfamily Lehimae. The larvae 

 of this subfamily of Carohidac are predaceous. 



Froctotrypes n. sp. Parasitic in larva of some insect. 



A Staphylinid of the genus Homalota. The species of this and 

 allied genera are certainly not injurious .to the fruit. 



A Coleopterous larva. (Dennestidael) 



Apharaeta n. sp. Probably parasitic on Anastrepha or else on 

 some Dipterous scavenger. 



I have not tried to cultivate in vitro, the Froctotrypes or the Apha- 

 raeta, because they seem to me of very little efficacy, even when 

 they have the best climatic conditions, and moreover they are very 

 scarce, and therefore the plague is causing great damages in the 

 Cuernavaca fruit, where the orchardists are still more indifferent 

 than at Yautepec, and do not pay any attention to the destruction 

 of the fallen fruit. 



I have made up my mind to keep up during the year the study of 

 the parasites of Trypeta ludens, at the various stations. Neither did 

 Mr. Froggatt find, at Yautepec, any important parasite of the orange 

 worm, and as to the parasites recommended by Compere, and which 

 he claims to have discovered in Brazil, they have been useless, accord- 

 ing to the information of Mr. Froggatt and Mr. Lounsbury. 



As to the Hexamerocera hrasiliensis, advocated by Von Ihering, thus 

 far it is not known whether it is efficacious.
