450 SNODGRASS 



HALMENUS CHORISTOPTERUS sp. nov. 



Distribution. — Charles Island. 



Description of the Type. Female. — Differs very markedly in the 

 following structural characters from all of the Indefatigable specimens 

 of H. robusius. Tegmina relatively very small and widely separated, 

 reaching only slightly beyond the second abdominal tergum ; their 

 posterior ends rounded, lateral margins symmetrical. Pronotum 

 strongly carinate mesially and latero-dorsally, lateral ridges not so 

 sharp as the median. 



General color yellowish-reddish-brown, much darker, than in U. 

 robustus. Black prozonal band not continued upon the metazona ; a 

 yellowish- white stripe borders the black prozonal band inferior ly ; the 

 whole of the lateral lobes of the pronotum below this stripe rugose, 

 mottled with reddish and yellowish-white. Tegmina brown bordered 

 laterally with white. One specimen of H. robustus has the right 

 tegmen bordered with pale brownish near the base. Abdomen brown 

 with small black blotches along the sides of the terga. Black bands 

 of the posterior femora but faintly indicated, almost obsolete on the 

 outer sides. 



'Y\\Q type is the only specimen obtained. Its measurements are : 

 length of body 34; tegmina 4.8; prozona 4; metazona 3.5 mm. 



HALMENUS CUSPID ATUS sp. nov. 



Distribution. — Albemarle Island ; Iguana Cove at sea level ; Tagus 

 Cove between 3,500 and 4,000 feet. 



Descriptio7i of the Type. Fejnale. — Much resembles the Charles 

 type of H. choristopterus but differs in its much smaller size and in 

 much more acute angle which the front forms with the vertex, this 

 latter character being very conspicuous, the angle being about 55 

 degrees, while in H. robustus and H. choristopterus it is about 75 

 degrees. Tegmina well separated along the median line, narrow, 

 reaching little past the second abdominal tergum. Pronotum mesially 

 carinate; lateral angles not quite so prominent as in the Charles type., 

 much more so than" in H. robustus. 



Head dark reddish-brown ; front dusky ; a black post-ocular stripe 

 narrowly and faintly margined above with yellow. Antennae annulate 

 with black and yellow basally, mostly dusky on the distal half. Doi"- 

 sum of prozona same color as the head ; a wide lateral black prozonal 

 band as in other forms, below which a light yellow line, and below 

 this, on both the prozona and the metazona to the lower margin of the 

 pronotum, yellow punctate with brown and with a large black spot on
