NOMIOIDES DECEPTOR, n. sp. 



Prsccedenti colore et pubescentia simillima, sed ab ea differt facie 

 utroque sexu longiore, a pulchello, variefjatoque thoracis pilis 

 squamiformibus facile distinguenda. 



Another species of very similar coloration and vestiture to the last ; 

 in the two males however which I possess one has a short black 

 band on the basal segment of the abdomen only and the other has 

 one on the 2nd segment also, in both the apical segments are more 

 or less piceons, in the two females both show a short black band on 

 the basal segment only, both sexes may be known from either fallax 

 or squamiger by the longer face. This is distinctly longer than 

 wide in the (^ , and oval not round in the $ , the face of the 9 much 

 resembling that of pulchellus although a trifle wider, the ^ has the 

 face much less constricted than in p^ilchellus and the farinose scale- 

 like pubescence distinguishes both the sexes from that species as well 

 as from variegatus or fallax. 

 Long. 85-4 mm.

NOMIOIDES EXCELLENS, n. sp. 



Precedentibus multo major scutello viridi seneo, flavo bimaculato, 

 abdomine utroque sexu flavo segmentorum apicibus nigro faaciatis. 



A species of almost twice the bulk of any of the preceding. It 

 has a round wide head in both sexes as in the 5 of deceptor and 

 is clothed with white deciduous pubescence as in that species and 

 squamiger but differs from both of them in its much larger size, and 

 in the colour of the scutellum ; this only bears two testaceous spots 

 as in the $ of variegatus, and the mesonotum of the $,just in front 

 of the scutellum, is testaceous. This also is a character of variegatus 

 but the broader face will distinguish it at once from that species in 

 the 5 and the pale abdomen with regular dark fasciae in the (^ . 

 These fascia? in both sexes are wide and cover the apices of the 

 segments, whereas in both squamiger and deceptor the fasciae in the
