Ephutomorpha macracantJia, sp. n. 



$ . Nigra ; segmento dorsali primo secnndoque linea angusta 

 apicali utrinque, tertioque linea basali utriiique argenteo-pilosis ; 

 secundo macula magna elongata utrinque, quarto quintoque 

 macula magna mediana griseo-pilosis ; capite magno, sub- 

 rectangulari, fronte inter antennas prodiicta, bidentata ; thorace 

 spina parva laterali utrinque ante medium ; area pygidiali 

 longitudinaliter striata. 

 Long. 11-14 mm. 



? . Mandibles very strongly bidentate at the apex ; second 

 joint of the flagellum nearly twice as long as the third. 

 Head very large, subrectangular, sligtitly narrowed poste- 

 teriorly, coarsely punctured ; a carina from the eyes, which 

 is produced above the base of the scape, forming a porrect 

 tubercle on each side between the anteunse. Thorax and 

 median segment coarsely reticulate, a little longer than the 

 greatest breadth, a spine on each side before the middle, 

 rather abruptly narrowed behind the spine, the anterior 

 angles not strongly rounded, the anterior margin about half 

 as wide again as the posterior, the truncation of the median 

 segment almost vertical. Abdomen sessile, the second 

 segment much liroader than long, closely and finely punc- 

 tured-rugose. Pygidial area longitudinally striated, smooth 

 at the apex. Intermediate and hind tibise strongly spinose. 

 There is a spine on each side at tlie base of the tirst 

 abdominal segment beneath.

This is another species of the sangid/iiccps-grou^, and 

 approaches that species very closely in the structure of the 

 head. The differences are marked in the stronger sculpture, 

 the bidentate mandibles, the shape of the thorax, with the 

 small lateral spines and without the small spines at the 

 apical angles, in the striate pygidium, the spinose tibiae, the 

 form of the patches of pubej>cence, aud the colouring. The 

 relationship to sanguiniceps is more remote than that of 

 latidentata.

I cannot find any structural difference between these 

 forms, and therefore look upon them as mere colour-varieties 

 of one species, hlanda occurring more commonly in the 

 south of Tasmania and concinna in the north. The species
