292 MODERN CLASSIFICATION OF INSECTS. 



death. He thus describes the larva : " Hexapus, pallide ochracea, 

 nuda, nitida,orenigricante; " adding (vol. xv. p. 511.), " Corpus spinulis 

 omnino indistlnctis exasperatum ; tracheae fuscoe ; mandibular ferru- 

 ginete ;" pupa " nitida^ oblonga, flavescens, linea dorsali ochracea, 

 oculis, mandibulis, membrisque saturatioribus." The habits of the pa- 

 rasite are thus doubtingly described : — " Nidis Xylocopaj Teredinis 

 nutritur. Forsan dum larva cibum apibus preparatum avide consu- 

 mit, hospes fame perit. Mox matura proprium nidum excavat ? in- 

 troitum claudit ac metamorphosin subit." W. Sells, Esq. of Kingston, 

 possesses Mr. Guilding's specimen of this larva, which is transfixed 

 with a pin and dried; so that it is now much more slender than repre- 

 sented above : it is also much more curved (like a Lamellicorn larva), 

 with deeply constricted segments ; the six legs very short, and the 

 extremity of the body entire. 



M. Westermann (in his letter to M. Wiedemann, published in Sil- 

 hertnmiiis Rev. Ent. No. 3.) has stated that in Java, Horia maxillosa 

 and testacea (G. Cissites Latr.) are found in houses, where they do 

 much damage to the wood work, by forming deep furrows, serving as 

 a retreat for their larva?; but, from the statements of Guilding given 

 above, it is evident that the Horise were parasites, and that the 

 injuries were caused by some other insects upon which the Horiaj feed. 



The fifth family, Mordellid.e * Leach, is distinguished by the 

 general form of the body, which is elevated and arched, with the 

 head inserted very low (^Jig. 33. 6. Mordella fasciata slightly mag-
