278 PERCY SLADEN TRUST EXPEDITION 



Matutinus, gen. nov. 



Vertex of head a little longer than broad, somewhat narrow, concave, a little 

 broader at base than at apex, the lateral margins strongly carinate, the apex triangulate ; 

 antennae with the first and second joints robust ; face very much longer than broad, 

 centrally and laterally strongly carinate, the central carination prominent at apex, two 

 small ocelli on posterior margin-; clypeus nearly half the length of face, centrally 

 carinate ; pronotum a little shorter than head, tricarinate ; mesonotum slightly longer 

 than head and pronotum together, tricarinate, the disk longitudinally flattened ; tegmina 

 more than twice as broad as long, the veins few and longitudinal, obliquely triangulate 

 beyond middle, the costal membrane broad; wangs considerably broader than tegmina*; 

 posterior tibiae unarmed. 



145. Matutinus opulentus, sp. n. (Plate 49, fig. 16 a). 



Body above black ; vertex of head (excluding lateral margins), and a central 

 fascia to pro- and mesonota, pale ochraceous ; basal area of abdomen pale testaceous ; 

 body beneath imperfectly seen in the unique carded type ; face black ; antennae 

 ochraceous ; tegmina faintly ochraceous, claval area paler with a dark fuscous spot at 

 apex, the apical area somewhat broadly dark fuscous, this coloration angulated on its 

 inner margin, before apex a large ill-defined whitish spot on costal margin, a similar 

 but smaller spot near apex of inner margin ; wings very pale fuliginous, their apices 

 (excluding an upper apical pale spot) fuliginous f. 



Long. excl. tegm. 3 mm. Exp. tegm. 8 mm.

Adolendana, gen. nov. 



Vertex long, produced in front of eyes, the margins very strongly ridged, the 

 disk being thus longitudinally concave, apex triangulate, base strongly concave ; face 

 elongate, narrow from apex to region of eyes and then ampliated and again a little 

 obliquely narrowed to base of clypeus, before which there are two small ocelli, the 

 lateral margins strongly ridged and centrally longitudinally carinate ; apex truncate ; 

 clypeus about half the length of face, laterally ridged and centrally carinate ; pronotum 

 very short, anteriorly conically produced ; mesonotum large, a little longer than head 

 and pronotum together, longitudinally tricarinate ; abdomen somewhat laterally com- 

 pressed ; posterior tibiae without spines ; tegmina somewhat narrow at base, ampliately 

 widened towards apex which is rounded, the base of costal margin distinctly gibbous, 

 costal membrane wider at apex than at base, apical cells elongate and distinctly 



* Since the unique type was figured and before the description was written, the wings were unfortunately 

 mutilated in an attempt to reset the carded specimen. The peculiar venation of the wings therefore rests 

 on the accuracy of a painstaking and accurate artist.
