On a new Genus and Species of Mantodea. 437 



LIII. — Description of anew Genus and Species (Parymenopus 

 Davisoni) of Mantodea from the Oriental Region. By J. 

 Wood-Mason, Superintendent of the Indian Museum, and 

 Professor of Comparative Anatomy in the Medical College 

 of Bengalj Calcutta, 



[Plate XVII. A.] 



A unique specimen of the interesting Orthopterous insect 

 described below is contained in a small collection of Man- 

 todea which has recently been sent to me for determination 

 by Mr. William Davison, Curator of the Raffles Museum, 

 Singapore, after whom I have much pleasure in naming the 

 species. 



Paeymenopus *, gen. nov. 



? . Allied to Ilymenopus, Serville. Eyes less produced 

 and devoid of non-faceted corneal spines, of which not a 

 vestige remains. 



Median lobe of vertex not produced into a horn, its ante- 

 rior end terminating in a slightly excavated isosceles-trian- 

 gular vertical area, which answers to the fluted front face of 

 the frontal horn in the allied genus. 



Pronotum oval, narrower, granulated on the disk, distinctly 

 toothed at the sides, with a moderate constriction near the 

 hinder end. 



Organs of flight shorter. Tegmina with the first branch of 

 the anterior ulnar vein only 2 branched, the v. plicata 4- 

 branched. Wings with the outer half of the anterior margin 

 and of the veins of the anterior area distinctly arched. 



Legs all identically the same in general form and struc- 

 ture ; the fore legs exactly the same ; the four posterior legs 

 with the inferior foliaceous crests of the femora moderate, at 

 their widest part hardly exceeding the greatest width of the 

 joint, and with all the other crests simple and unexpanded. 



Distribution. The Malayan subregion of the Oriental 

 Region. 



The absence of a frontal horn and of non-faceted corneal 

 spines readily distinguishes the new genus from the old. 



Parymenopus Davisoni, sp. n. 



$ . Head Indian-yellow, unmarked. Pronotum distinctly 



* From mipa ami Hymcnopus, generic w&\\m = Trapvixtv6iTovs = Pary- 

 menopus.
