oblique; connexivum exposed from about half the leugth of 

 corium ; membrane almost reaching abdominal apex, the 

 veins longitudinal; bucculae strongly roundly elevated for 

 about their apical halves; rostrum reaching the posterior 

 coxae, first joint reaching base of head, second nearly twice 

 as long as third and fourth together; sternum centrally 

 sulcate; legs of moderate length, anterior tarsi with the 

 second joint shortest, posterior tarsi mutilated in type ; 

 abdomen beneath moderately convex. 



In general appeai'ance allied to ^lia, from which it is 

 altogether distinct by the subequal length of the lateral and 

 central lobes of the head ; allied to Ltubentius by the elevated 

 bucculae and sulcated sternum, but differing among other 

 characters by the non-sulcated abdomen beneath. 



Pseudalia dementi, sp. n. 



Bright ochraceous with prominent longitudinal black 

 fasciae ; two central black fasciae commencing at apex of 

 head, where they are fused and continued, through head, 

 pronotum, and scutellum, on the apical area of the latter 

 they are attenuated and terminate a little before apex, 

 lateral margins of head black ; pronotum with a sublateral 

 fascia and a short basal one between it and the two central 

 fasciae ; extreme lateral margins of scutellum black ; corium 

 with two broad black fasciae united at base, but not on 

 apical margin ; membrane greyish, with longitudinal black 

 fasciae broadly covering the veins ; connexivum ochraceous ; 

 body beneath ochraceous, with two longitudinal black fasciae 

 on each side and a central fascia on abdomen, these fasciae 

 are a little narrower than those above and on the head are 

 somewhat broken ; legs ochraceous, subapical annulations 

 to femora, apices of tibiae, and the tarsi black ; above 

 strongly coarsely punctate, especially in the black fasciae, 

 some of the intervening pale spaces being levigate and 

 impunctate ; antennae ochraceous, fourth and fifth joints 

 more or less infuscate ; sides of the buccula>, apical area of 

 head beneath, acetabula, and the anterior and posterior 

 margins of the sternal segments more or less strongly 

 punctate ; other structural characters as in generic diagnosis.
