 H. patruelis, v. d. Wulp, is recorded from Celebes. 



Heligmoneura lascus, Walker. 



Types ( c? ? ) from Coleuso, New Zealand, also recorded 

 by Hutton from Auckland and Wellington, New Zealand. 



The types presented by Dr. Hooker are not identifiable, 

 but there are male and female specimens from New Zealand 

 (Col. Sinclair, 1845) and otliers (Col. Botton, 1854), which 

 agree with the description given by Walker. This species 

 and another new species from New Zealand, S. meridion- 

 alis, were placed by Hutton in the genus Sienoprosopis, 

 containing species from America, with the exception of one 

 from Bengal ; this species, however, belongs to Heligmoneura, 

 having the face very narrow, raised round the mouth, forming 

 a very slight tubercle (in Stenoprosopis the face has no 

 tubercle and the moustache is composed of only a few long 

 hairs), and appears nearly allied to H. gnava, v. d. Wulp, 

 from Java, Obi, Halmaheira, and Waigiou. Stenoprosopis 

 meridionalis, Hutton, Trans. New Zealand Inst, xxxiii. p. 23, 

 will probably prove to be a species of Heligmoneura. 



H. lascus is described as a small species with reddish- 

 yellow legs, the abdomen black, with rather broad greyish or 

 dull yellowish segmentations. Wings clear, grey at apex 

 and round posterior border. 



Length 12-13 mm. 



Description from fresh specimens from New Zealand
