Cameron, Description of three undescribecl species of Chalcididae. 207 



versely ; the labrum light brown. Mandibles black, brown at the 

 base ; they are large, broad , bluntly tridentate , the inner tooth 

 less distinct than the others. Eyes large , distinctly converging 

 above ; they are closely pilose ; the nialar space half the length 

 of the antennal scape. Behind the head is quite transverse ; the 

 temples are absent above and are narrowed below. Prothorax 

 large , nearly as long as it is wide at the apex , towards which 

 it beconies gradually widened ; it is smooth. Mesonotuni finely, 

 closely shagreened ; the apical two - thirds are broadly depressed 

 in the centre. Scutellum large , longish oval , rounded at the 

 base and apex , widened gradually , but not much , towards the 

 apex , the sides below with a narrow furrow ; it has a,n oblique 

 slope ; on eitherside of the base is a stout semi - circular pro- 

 jection , bordered by a transverse furrow behind. Metanotum 

 depressed in the niiddle , the apex bordered by a furrow ; the 

 spiracles large , oval ; below them is a longitudinal furrow ; the 

 lower edge projects. The abdomen is hardly so long as the 

 thorax ; it is sessile and becomes gradually narrowed towards the 

 apex ; its back is rounded, the apices of the segments are trans- 

 verse ; the last dorsal segment projects over the ventral as a 

 broad, bluntly rounded at the apex, spine. The 4 front legs are 

 long and slender, the middle much longer than the anterior ; the 

 anterior spur short, the middle large, broad, three fourths of the 

 length of the metatarsus ; the posterior minute ; the hind tibiae 

 are narrowed at the base , becoming widened towards the apex : 

 they are compressed , especially above , where they are narrower 

 than they are below ; the tarsi are also compressed above at the 

 base ; the metatarsus is thicker than the others and is as long 

 as all of them united. 



The antennae are rather slender , thicker towards the apex, 

 the last Joint is obliquely truncated ; the basal two joints of the 

 flagellum are much shorter than the 3'''^ , which is longer than 

 them both united ; they are equal in length. The head is a 

 little wider than the thorax ; the ocelli are in a triangle. 



This species appears to be a Metapehna , as defined by the 

 tables of Ashmead (Mem. of the Carnegie Museum, I, 288). 

 According to this Author the Halidea of F o e r s t e r (= Halidayella 

 D. T.) is the same genus (l. c. p. 376). Probably he is correct 

 in this , but no mention is made by the German Author of the 

 eyes being hairy. 



Philopison carinigena Cam. 



The systematic position of this genus has been unfortunately 

 omitted in the description-in Deutsch. Ent. Zeitschr. 1908, p. 560. 

 It belongs to the Eurytomidae and to the Eurytomini.
