88 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



VII small, rounded and weakly sclerotized latero-ventrally. Dorsal setae : f.s. occasionally 

 present on segments I (0-2, average o-6) and V-VII (up to 3) ; usually one h.s. on I and each of 

 segments IV— VII. Pleural setae : absent on segments I, II and usually III, on segments IV-VI 

 consisting of dorsopleural setae : usually 2 h.s. on each of segments IV-VI, and ventropleural setae : 

 usually one h.s. and occasionally one f.s. on segments V-VI. Segment VII with 4-1 1 (average 

 8) f.s. and 3-5 (average 4) h.s., some of the posterior h.s. somewhat longer than rest. Ventral 

 setae : 3-14 (average 9), 3-14 (average 9), 0-9 (average 3-7), 0-7 (average 2-6), 0-6 (average 3-3) 

 and 1-9 (average 4-9) f.s. respectively ; h.s. : none on II, usually one on each side on III and 

 IV, and usually 4 on each of segments V-VII. 



Segment VIII with weak tergite and transverse sternite ; caudal extension forming a small, 

 simple lobe ; glandular pouch absent, replaced by a shallow depression and one long pointed 

 seta. No IXth tergite observed. Ante-anal setae absent, but 2-6 (average 3-9) small, circular 

 pores present. Posterior margin with 2-4 (average 3) h.s. on each side, one of these situated 

 more laterally on caudal extension. 



Genital segment. Penial sheath short, about | to | total body length (ratio 1 : 6-1-7 -3, 

 average 67), 152-186 (average 173) [x long and 30-38 (average 34) [/. wide ; lateral sclerotiza- 

 tions narrowly joined anterior to anus ; basal rod about as long as aedeagus, extending anter- 

 iorly from base of aedeagus to between £ and f of the distance to apex of the basal membranous 

 area ; apex of sheath without membranous extension. The area from base of sheath to tip of 

 aedeagus with 18-26 (average 22) small setae ; a cluster of small sensilla occurring ventrally 

 near apex of sheath. Aedeagus short (40-53, average 46 u. long), penial sheath and basisternum 

 longer, the ratios being 1 : 3-2-4-3 (average 3-8) and 1 : 1-57-2-29 (average 1-97) respectively. 



Material examined : 10 specimens, bred in the laboratory from material collected 

 by myself on Luzula campestris (L.) at the Imperial College Field Station, Silwood 

 Park, Sunninghill, Berks. ; males emerged during May, 1962 ; the species was 

 found to be bivoltine in the field. 



The INGLISIA Group 



INGLISIA 



Inglisia theobromae Newstead 



(Text-figs. 29 and 30) 



A medium-sized and moderately robust species, with comparatively long antennae and 

 moderately long legs ; with numerous setae on the body and appendages. When mounted, 

 total body length 1610-1790 (average 1710) u. ; width at mesothorax 370-420 (average 399) y.. 

 Wing expanse 2870-3270 (average 3032) \i. 



Head subcorneal in dorsal view ; in lateral view obliquely elongated, with the anterodorsal 

 bulge not pronounced ; length from apex to pronotal ridge 209-262 (average 245) u., width 

 across genae 251-277 (average 266) y.. Median crest well sclerotized, especially around the 

 posterior margin, which is obtuse ; weakly polygonally reticulated ; with 4-1 1 (average 7-2) 

 fleshy and 10-14 (average 13) hair-like dorsal head setae. Midcranial ridge dorsally absent ; 

 ventral part with median bar reduced posteriorly, the lateral arms widely diverging, and the 

 surrounding area weakly sclerotized and reticulated. Genae large, sclerotized, not reticulated ; 

 each with 5-1 1 (average 7) fleshy and 0-4 (average 1-2) hair-like genal setae. Eyes : four 

 pairs ; dorsal and ventral pairs large, subequal ; lateral pairs large, only slightly smaller than 

 dorsal and ventral eyes, subequal ; corneae of dorsal eyes 32-37 (average 35) u. in diameter 

 and 1 -6-2-1 (average i-8) times as much apart ; those of the ventral eyes 30-36 (average 34) y. 

 in diameter and o-6-o-8 (average 0-7) times as much apart. Ocellus small. Ocular sclerite
