148 FAMILY EVAXIID^E. 



as much as the tliird joint ; the palpiger distinct. Tlie head behind 

 the eyes and vertex is more or less narrowed, a carina of varying 

 distinctness separating it from the gular regions. 



The neck is short. The pronotum (Fig. 19) consists of a trans- 

 verse vertical piece, constricted in the middle and usually smooth 

 and polished ; the lower edge is more or less produced forward into 

 a short transverse collar; the humeral angles (Fig. 19) are promi- 

 nent or rounded ; the upper edge is emarginate in the centre, the 

 mesouotum fitting into the emargination ; the propleurse and venter 

 are not distinct, but small and concealed beneath the head, as is 

 always the case in the subfamily (Fig. 19). The mesonotum and 

 scutellum form together a more or less convex area, and are sepa- 

 rated from each other by a transverse straight suture that is often 

 not plain ; the anterior and lateral grooves are absent, the parapsi- 

 dal grooves are not present in an}' species in our fauna, or at least 

 not more tlian a trace of them anteriorly ; in West Indian and 

 other exotic species they are distinct, but when so are usually placed 

 a little nearer the middle than in Evania ; the mesopleur^e have a 

 highly polished impunctate or minutely punctulate area occupying 

 more or less of tiieir upper surface (Figs. 1, 6 and 7); this area is 

 generally broken above by a circular pitted area, and has usually 

 some irregular pits in the middle; its shape and extent, and the 

 depth and shape of a large oblique fossa or depression traversing 

 the forward part of it, and forming a receptacle for the femora are 

 characters of s])ecific importance; anterior to the depression the 

 pleurae are swollen into an oblique broadly rounded ridge, the punc- 

 tation of which is usually sparser than on the dorsum, but similar 

 to the venter, from which it is not separated. This area I have 

 spoken of as the anterior swelling of the mesopleurse. The meta- 

 notum (Fig. 63) is a very narrow transverse strip, depressed between 

 the scutellum and propodeum, the edges of which form gradually 

 sloping walls for it (Fig. 63). On the metapleui-se there is ante- 

 riorly a very narnnv punctured area, interrupted mesally, behind 

 which there is an oblique well marked carina, parallel to and behind 

 this carinie is a broad fossa of varying depth, and the natui-e of the 

 reticulations in this fossa and on the propodeum just behind it is of 

 great s[)ecific importance (PI. V); these may be long and narrow 

 with few or no cross bars, or nearly square, and there may be from 

 one to three rows; one or two oblique carinie may be present, one
