ARCTURUS GRANULATUS, new species. 



Body narrow, elongate, about 

 four times as long as broad, 4 

 mm. : 15| mm. Surface of body 

 rugose, with the anterior and pos- 

 terior margins of all the segments 

 furnished with a row of tubercles. 

 Abdomen covered with low tu- 

 bercles. 



Head a little wider than long, 

 \\ mm.; 2 mm. Front deeply 

 excavate, with the antero-lateral 

 angles produced. There is a small 

 median point. The eyes are large, 

 round, composite, and paced close 

 to the lateral margin, about half- 

 way between the anterior and the 

 posterior margins. The rugosities 

 on the posterior half of the head 

 form two Ioav elevations, one on 

 either side of the median line. 

 The first pair of antennae have the 

 basal article large and dilated; 

 the next two articles are slender 

 and subequal; the fourth article is 

 about twice as long as the preced- 



ing article and extends to the end of the second article of the second 

 pair of antennae. The second pair of antennae have the first article 

 very short; the second is longer and is about 1J mm. long; the third 

 is 2J mm. in length; the fourth is twice as long as the third, being 

 5 mm. long; the fifth is almost as long as the fourth, being 4J mm.; 

 the flagellum is 2 mm. long and is composed of seven articles.
