Brockenhurst where Cross also found it, Perry Wood and Matley Bog in 

 the Now Forest still between the same dates, which render one chary of 

 acceptinn van Burgst's and Tosquinet's records.

 Ent. Ross. 1899, p. 136. 



A somewhat stout, rufescent-testaceous species, with the abdomen not 

 infrequently a little infuscate ; the largest species of Parabatus. Head 

 not constricted posteriorly, nearly as broad as eyes, ocelli large and orbits 

 subflavidous. Antennae .subattenuate and entirely testaceous. Thorax not 

 flavous-marked ; metathoracic transcarina always very distinct on either 

 side, its spiracles oval. Scutellum very strongly carinate laterally to apex. 

 Terebra reflexed and not longer than the truncate anus is high. Hind 

 tarsi stramineous or whitish. Stigma clear, sometimes pale, testaceous; 

 basal nervure continuous. Lengtli, 9-14^ nun. 



Distinct from P. lu'i-gaiiis in colour and the oval spiracles ; and from 

 P. la/inigula in larger size, distinct metanotal cristae, longer basal seg- 

 ment and its basal foveae, third segment margined to spiracles and more 

 strongly carinate scutellum. Doubtless all three were included under the 

 first name by (jravenhorst and the older authors, including Newport, 

 whose notes under that species probably relate to the present. 



First recorded as British by Bridgman (Trans. Ent. Soc. i88g, p. 420) 

 on a solitary bred female from Stornoway. It is noted from Sweden by 

 Thomson, as often common in (icrmany by Schm., bred in France from 

 Sanvlhn'pns rcTavana by (iaulle, and Belgium in Ma}- and August by 

 Tosq. With us it is frequently bred but uncommon on the wing : Fresh- 

 ford near liath (Charbonnier), Felden (Piffard), (Juestling in 1887 (Bloom- 

 field ; [omit P. '('irgaltis from Sussex "\'ict. Hist.]), and the New Forest 

 (Miss Chawner) ; I took one at Ipswich in 1893 and another female 

 aniong alders at Reydon near Southwold on 2nd July, 1906. ()n 8th May, 

 1 90 1, Montgomery sent me a male, just emerged from its own cocoon 

 within that of Ha/ias prasiiiana, from Chalfont Road, Bucks ; on 4th May 

 19 10, W.B. Davis sent a male, three of which had just emerged from 

 their own cocoons ex the same host at Stroud, (jIos.; on 13th May, 1909, 

 Parkinson Curtis sent a female from a "pupa" of the same host from 

 Cranborne, Dorset. Cross also bred a couple of females at Brockenhurst 

 in May, 1902, from Eupilhuia; Adams raised it from Dicranura furcula 

 m the New Purest in 1901 ; and W. F. W'attam has given me another 

 raised by him at Huddersfield from Pryp/idtiia pronuha. Two females 

 were bred by Eric Shaw from Manchester Hadcna pisi on loth June, 1903 ; 

 and Clutten sent me twelve cocoons of this parasite from the same host, 

 found at liurnley, on 30th December, 1901. The first male emerged on 

 4th Ai)ril following and 1 was attracted to it bv the noise its mandibles 

 were making upon the i anllxiard >>\ its Ixi.x ; the second was out on i2tli 

 morning; third on 13111, between i and 10 pm.; fourth and fifth on i4lh 

 by II a.m.; sixtli (first 9) ""i '^'h '») "' a. 111.; seventh (J) by 4 p.m. 

 the same day; eighth (9) <"^ 2olh by 10 a.m.; ninth (9) I opened and 

 preserved in spirits; the ti-nth and last ( 9 ) emerged on 21st between 

 II a.m. and 10 i).m.; eleventh died of mould as a larva; and the twelfth 

 cocoon produced the L'xe/ashs tiign'pis referied to at Iclui. Pjril. iii. 298.
