Subfani . OxruAi.my.K. 



Genus Oxvii ai.oa, \\\\ 



Oxyhaloa variabilis, sp. n. 



? . Rufo-castaiicous. Vertex of head riifo-castaneous, a 

 clear testaceous baud between the auteuuic, geiiic testaceous ; 

 frons, clypeus, labrum, palpi, and antenna; shining black. 

 Pronotum with two oblique impressions anteriorly, with a 

 few minute punctures from which spring short slender hairs. 

 Tegmiua with the veins fuscous, sparsely pubescent, very 

 variable in length, in some examples reaching tip of abdomen, 

 in others lanceolate and extending no further than the third 

 tergite ; thirteen costals ; diseoidal field i-cticulate. Wings 

 as variable in length as the tegmina, flavid at base, the icst 

 infuscated; veins fuseous, ulnar vein with eight to nine rami, 

 the basal ones transverse. Abdomen broad, black above, 

 the margins of the segments narrowly rufous, beneath rufo- 

 castaneous ; supra-anal lamina short with rounded posterior 

 angles, not emarginate ; subgenital plate jjrojecting l)eyond 

 the supra-anal lamina, fuscous, ample, its margin sinuated ; 

 cerei short, fuscous, tipped with rufous. Legs black, apices 

 of coxa; and femora rufous, tibial spines rufous. 



Total length from 1(3 mm, to 13'5 mm. ; length of body 

 from IG mm. to 12'5 mm. ; length of tegmina from 11 mm. 

 to 8 ram. ; breadth of pronotum from 6'2 ram. to 5 mm. ; 

 lengtli of pronotum from 4"5 to 4 mm. 



Interior of Djibouti (Hermann) ; one example (Paris 

 Museum). 



This is the smallest species of the genus, and is remarkable 

 on account of the variation in size of the wings and tegmina ; 

 apparently this variation bears no relation to the variation 

 in size of the individual, for one of the smallest specimens 

 has long tegmina and one of the largest has these organs 

 much reduced. 



Genus Paraplecta, nom. nov. 



(= CirpAis, StKl) 



The name Cirphis, created by Stal in 1876 (O^fv. A'et.- 

 Akad. Forh. xxxiii. p. 74) for a cockroach {C. pallipcs) from 

 Daraara Laud, is preoccupied, having I)ecn applied by Walker 

 in 1805 to a genus of Noctuid moths.
