32 PEECT SLADEN TEUST EXPEDITION. 



between eyes at base, the margins strongly sinuate before eyes, lobes about equal in 

 length or the apex of the central lobe very slightly prominent, coarsely punctate, 

 ocelli at base near eyes ; antennae with the first joint slightly passing apex of head, 

 second longest, third a little shorter than fifth ; rostrum almost reaching the apex of 

 third abdominal segment ; scutellum moderately convex, somewhat coarsely jranctate, 

 obscurely transvei'sely wrinkled, the apex depressed ; corium finely punctate ; meso- 

 sternum centrally longitudinally sulcate. 



Long. 9^ to 12 millim. 



Locality. Seychelles Islds. 



Allied to S. urolaboides, Sign., but difi"eriug by the longer and more elongate head, 

 longer rostrum, &c. ; from the other described species it may be distinguished by the 

 central pale line to the pronotum and scutellum. 



Subfamily Acanthosomatinse. 



MAHEA, gen. nov. 



Body depressed, in cJ posteriorly attenuated. Head shorter than pronotum, about 

 as long as space between eyes, narrowed in front of eyes to apex, the lateral margins 

 concavely sinuate and with the apical margin somewhat strongly reflexed, lateral lobes 

 slightly longer than the central lobe, but not quite meeting in front of it; antennse 

 four-jointed, basal joint stoutest, about reaching apex of head, second joint longest, 

 about as long as third and fourth joints together, third a little longer than fourth ; 

 rostrum reaching the posterior coxte, second joint slightly shorter than the third and 

 about equal in length to the fourth ; pronotum as long as broad, deflected and narrowed 

 anteriorly, lateral margins moderately concavely sinuate, anterior margin subtruncate, 

 a little produced behind eyes, posterior angles strongly produced in slender acute spines, 

 posterior margin concavely sinuate before scutellum ; scutellum longer than broad, 

 transversely depressed near middle, and thence narrowed to apex, the lateral margins 

 a little convex before and after the medial depression ; corium somewhat narrow, 

 posteriorly acutely attenuated and reaching tlie middle of the membrane, their posterior 

 inner margins concave, membrane slightly passing the apex of the abdomen, the veins 

 longitudinal ; sternum with a raised longitudinal process between the anterior and 

 posterior coxae; abdomen beneath centrally longitudinally ridged, on each side obliquely 

 deflected, in the 6 with an acute spine on the posterior angles of the apical segments, 

 in the ? more continuously spined from base, the spines on basal area very short, 

 and the third spine before apex broadened, flattened, and toothed ; legs simple, the 

 posterior tibiae curved ; the ? is also less posteriorly attenuated than in 6 ; tarsi 

 with two joints. 



7. Maliea sexualis, s^^. n. (Plate 4. figs, d 4, 4a; 2 7.) 



Head ochraceous, with coarse brown punctures, two longitudinal series of black 

 punctures on each side of the lateral lobes ; antennae castaneous, the basal joint more
