the Australian Longicornia, 555 



anothei* on the fourth upper abdominal segments, and a band on 

 each of the three inferior basal segments, clear lemon-yellow; sterna 

 and legs covered with a whitish pile ; prothorax rounded at the 

 sides ; elytra diverging posteriorly, each terminating externally in 

 an acute angle, which, owing to a short incurvation, is slightly 

 hooked, the external margin gradually incurved behind the 

 shoulder. 



Length 10 lines. 



This is one of the best marked species of the genus, although 

 allied to Hesthesis cingulatus. The form of the elytra, beginning 

 to diverge at about half way from the apex of the scutellum, and 

 the clear lemon-yellow of its numerous markings, are sufficiently 

 distinctive. I have seen only one example. 



Dr. Howitt mentions a " common" species at Melbourne hav- 

 ing red antennas, which appears to be near Hesthesis cingulatus. 

 This is probably undescribed. 



2. Hesthesis murinus. 

 H. niger ; elytris integris, linea suturali postice curvata, alba ; 



abdomine supra fascia alteraque infra albis. 

 New South Wales. 



Black ; elytra greyish ; front, anterior margin of the prothorax, 

 a band on the upper and another on the lower basal segments, sil- 

 very-white ; a short oblique patch of the same colour towards the 

 posterior margin of the elytra, connected with a paler stripe along 

 the suture ; prothorax nearly as long as broad, rounded at the 

 sides, covered with a sparse greyish pile ; elytra rounded at the 

 sides, nearly truncate at the apex; femora brownish-red; body 

 beneath with scattered greyish hairs. 



Length 6 lines. 



As the elytra in Hesthesis only cover the metathorax, the 

 whole abdomen above is visible through the transparent wings ; 

 and it is therefore necessary to observe, that the first or upper 

 basal segment of the abdomen does not correspond with the basal 

 segment beneath, and that this forms one of the five abdominal 

 rings in connexion with the second upper, and so on for the re- 

 mainder. 



Mr. Newman describes the males o^ Hesthesis as having 12- 

 jointed antennae. This is an error. The eleventh joint, it is 

 true, is notched in the middle, as it very often is in this family, 

 but the slightest examination will show that it is only a notch. 



It is very likely that in some individuals of the same species
