structure of the clypeus which so closely corresponds with that of Oedema- 

 iopsis, conduce to the opinion that it is best placed, at least tentatively, 

 under Dicjdegnia. I must own, however, that Forster's meagre diagnosis 

 of this genus is quite unintelligible to me and I simply adopt the name 

 because such points as he indicates are possessed by my insect, and I am 

 not aware that any species have before been described under this genus. 



1. anomala, sp.n. 



Head black with short grey pilosity ; palpi, extreme apex of clypeus, 

 cheeks, a subtriangular facial mark, and the internal orbits to ocelli broadly, 

 white ; remainder of mouth and face ferrugineous. Antenne infuscate, 

 with the scape rufescent beneath. Thorax dark red or badious, with fine 

 grey pilosity, mesonotum black ; pronotum and propleurae, callosities 

 before and beneath radix and beneath hind wings, lateral marks on meta- 

 thorax and the dentiparal areae, flavous. Scutellum flavous. Abdomen 

 entirely brunneous, with the apices of the second and seventh segments 

 flavous, and of the remainder rufesrent. Legs dark red with the hind 

 femora brunneous ; anterior coxae and trochanters entirely, apex and a 

 large mark before base of the hind coxae above, and the three central 

 joints of the hind tarsi, white. Wings hyaline with the stigma ochraceous 

 and radix flavidous. 9 • Length, 7 mra. 



As I have remarked above, this species is somewhat incongruous wherever 

 it may be placed. The subpetiolate abdomen, broadly pentagonal areolet 

 and position of the petiolar spiracles ally it with the Crypt inae, irregular 

 areolet, elongate legs and apically compressed abdomen with the Ophioni- 

 nae ; and it has as much relationship with the Trjphoninae as has Thy- 

 wan's, to which it, in spite of the areolet, appears most closely associated. 



I possess only a single female, kindly presented to me by Mr. Stanley 

 Edwards, who took it at Lynton, in Devonshire, in 1890. 



THYMARIS, Forster. 



Verb. pr. Kheinl. 18(38, p. 151 ; Thymanis, Thorns. O. E. ix (1883). 'J08. 



Head as broad as the thorax, circularly narrowed behind the eyes, with 

 the vertex only slightly broader than long ; clypeus arcuately discreled, 

 subconvex and apically very slightly rounded; eyes densely and very finely 

 pilose, prominent, large and extending to base of mandibles, which are 

 weak and apically narrowed with the lower tooth the smaller ; cheeks 

 short and not buccate ; face of V anteriorly contracted. Antennae nearly
