In its size and coloration so much resembling Jf". tetragrammicus, 

 that it is possible to confound the two species; but sufficiently distinct. 

 Blacliish-brown, with slight griseous pubescence ; head small ; front 

 black ; mouth yellow ; labial palpi black externally, tbe terminal joint 

 much swollen before the apex ; antennae longer than the thorax, mode- 

 rately clubbed at the apex, black, the apex of the joints narrowly ringed 

 with yellow, the basal joint yellow beneath ; occiput swollen, yellow, 

 with two rows of quadrangular black points, which anastomose and 

 form two transverse lines ; two geminated spots in the middle near the 

 pro-thorax ; pro-thorax broadly excised in front, greyish-brown, with a 

 line in the middle, and a band on each side (separated into two) yel- 

 lowish ; meso-thorax similarly marked ; the bands are interrupted on 

 the thorax, and in a way separated into spots ; abdomen long, thin, 

 brown, with a yellow spot on each side of the base of the antepenulti- 

 mate segment, and probably also on the preceding segment ; legs weak, 

 veiy pubescent or ciliated with greyish-yellow, the apex of the thighs, 

 the tibiae at the base, in the middle, and at the apex, annulated with 

 black ; spurs of the anterior legs as long as the four first of the 

 tarsal joints ; wings long, narrow, hyaline, with the neuration veined 

 with yellow and brown, especially on the longitudinal veins, a short 

 oblique brown line on the posterior border of the anterior wings, where 

 the oblique branch of the fifth longitudinal vein unites with the margin ; 

 a similar spot before the apex ; pterostigma white, marked with brown 

 internally ; posterior wings without spots, the nervures visibly ciliated. 



Madeira. I have seen four specimens, and also the Fabrician type 

 in Banks' collection. 



M. catta pertains entirely to Eambur's group of M. tetragram- 

 micus. Brulle (1. c. p. 83) cites M. lituratits of Olivier as found in 

 Madeira, and suspects the example to be a variety with the abdomen 

 more obscure, and the spots on the wings much less marked. But 

 lituratus, Oliv., from the south of France, and from Greece, is probably 

 a distinct species, equalling M. nemausiensis of Scriba and Burmeister. 



Lastly, M. hjalinus of Olivier figured on pi. 3, fig. 5, as found in 

 Madeira, is to me totally unknow}i. The figure is bad ; perhaps it will 

 belong to the group of M. distinguendus of Eambur. 



No. 33. 



{To be concluded in our next.)
