and Species of Longicorns. 275 



narrower prothorax, sparse pvibescence, and femora without 

 spines at the apex, most nearly approaches the typical forms 

 of the genus, such as D. columbina, Serv. ; in colour it is 

 somewhat like D. ruipes, Bates. The long hairs beneath the 

 antenna in this and allied genera are, I believe, only found in 

 the early life of the insect, and are not dependent on sex, as 

 Lacordaire supposes. 



Melegena cyanea. 



M. nitida, violacea, elytris cyaneis, sparse erecto-pilosa ; capite vage 

 puuctato, labro palpisquc flavis ; antennis tenuibus, sctaceis, cor- 

 pore fere duplo longioribus, articulis diiobus basalibus flavis, 

 caeteris apicem versus infuscatis, basi sordide fulvis ; prothorace 

 paido longiorc quam latiore, disco subquadrituberculato (2 . 2), 

 vage punctate ; scutello nigro ; elytris modice elongatis, pubc 

 subtilissima sparse vestitis, apicibus subemarginatis, baud spi- 

 uosis, sat fortiter punctatis, punctis apicem versus evanescentibus ; 

 corpore infra nitide violaceo, pube subtilissima sericante induto ; 

 pedibus fulvis, femoribus intermediis et posticis parte clavata 

 violacea. Long. 6 liu. 



Hah, Cochin China. 



A proportionally shorter form than the Borneo M. puhi- 

 peunis, with more slender antennae, the apices of the elytra 

 not mucronate, &c. Melegena, inter alia, is distinguished 

 from Noemia by its coarsely facetted, reniform eyes. (See 

 Trans. Ent. Soc. ser. 3. iii. p. 659.) 



Temnosternus vitulus. 



T. piceus, pube grisea tectus ; capite dense pubescente, linea media 

 excepta ; prothorace valde disperse punctate, vittis tribus minus 

 pubesceutibus ornato ; elytris oblongo-ovatis, remote punctatis, 

 apicibus oblique truncatis, augido exteriore breviter mucronato, 

 postice fascia lata pubescente, margiuibus dcnudatis, ornatis, 

 singuHs costis duabus longitudinalibus munitis, costa exteriore 

 abbreviata ct minus determinata ; corpore infra castaneo, uitidis- 

 simo, lateribus pubesceutibus. Long. 5 liu. 



Hah. Queensland (Wide Bay). 



Something like T. planiusculuSyWh.; but that species, ^'?^/cy• 

 alia, has the elytra gradually drawn out into a point. 



Ancylonotus nasicornis. 



A. fuscus, pube plerumquc fuscescente tectus ; capite inter antennas 

 fortiter excavato, supra clj^jeum coruu triangulari porrccto ar- 

 mato ; scapo modice elongato, articulo tertio flexuoso, duobiiH 

 soqucntibus conjunctim longiorc; prothorace transverse, anti('(>
