THE CANADIAN ENTOMOLOGIST. 103 



making the metanotum nearly a third longer than the pronotum. Median 

 carina distinct but faint on the metanotum, on the pronotum visible only 

 as longitudinal rugosites. Lateral carina? present only on the metanotum,. 

 and there very blunt, scarcely more than rounded shoulders. Thorax 

 obtusely angled behind, in front truncate, but considerably produced in the 

 middle. Lateral lobes subperpendicular, subangulate at the posterior 

 angle. Interspace between both meso- and metathoracic lobes very 

 strongly transverse. Tegmina and wings very long and slender, especially 

 the former, which is nine times as long as the middle breadth. Humeral 

 shoulder slight. Intercalary vein moderately strong, transversing nearly 

 the middle of its area. Posterior femora moderately slender, the dorsal 

 carina considerably elevated. 



This genus has a general resemblance to Trimerotropis, Conozoa, 

 Psinidia and Anconia, but differs in some particulars from all of them. It 

 is probably the most nearly allied to Anconia, by reason of the slight 

 development of the median carina on the pronotum, but is readily 

 separated from that monotypical genus by the form of the frontal costa, 

 the rugose metanotum and the more elongate elytra. 



3. ARAEOPTERYX PENELOPE, nOV. sp. 



One female; Prescott; September 29, 1900. 



Head of a uniform reddish brown colour with a number of somewhat 

 minute fuscous spots on the facial carina? and the margins of the fastigium 

 and frontal costa. Eyes quite prominent, almost globular, not so long as 

 the infraocular portion of the genae and concolorous with the head. 

 Antenna? black, except the first and second segments, which are light. 

 Thorax reddish brown, with the prosternum pallid. The sides with an 

 oblong black mark extending diagonally across the middle, directed 

 upwards and backwards and terminating before it reaches the posterior 

 border of the metathoracic lobe. This is very probably a variable 

 character, as it differs slightly on the two sides of the present specimen. 

 Elytra more than twice as long as the posterior femora, very slender, 

 gently inclined backwards distally and membranous over most of the 

 apical half. Ground colour a shade lighter than that of the thorax and 

 somewhat irregularly maculate throughout with fuscous, the infuscation 

 being most conspicuous on the humeral angle and an oblong space at the 

 end of the basal half of the costal margin, where it is quite dense. Wings 

 considerably more than twice as long as the greatest width, base reddish 

 pink in colour, beyond hyaline with infuscation along some of the veins
