Early Stages of Coleoptera. 343 



The abdominal segments i to 5 are rosy beneath, with a large 

 quadrate median basal brown spot and on each side of this a 

 large sub-orbicular or oval one. The remainintr segments 

 have as ground color a creamy white, the markings on the 

 sixth and seventh segments being the same as the preceding 

 ones. The last two are plain. The legs are creamy white 

 except the bases of the coxce and some longitudinal stripes on 

 the other joints, which are brown. 



Form elongate, somewhat depressed, tapering behind. 

 Length 36 mm. 



Head very small, covered in great part by the prothorax. 

 Most of the mouth parts and a quadrate mark reaching from 

 near the base to the frontal margin are castaneous. The 

 form of the head is peculiar, the appearance being as if a 

 tube were extended from the prothorax, the mouth parts and 

 antenna protruding from the end of this. I presume that the 

 head is strongly retractile. 



Antenute with the basal joint immensely thick, the second 

 shorter and much more slender, the third approximateh^ equal 

 in length to the second but of less diameter, the fourth very 

 minute. All bear bristles. In color the first joint is white, 

 the second is of the same color but with a brown band at 

 about the middle of its length, the remaining two being cas- 

 taneous. 



The mandibles are strong at the base, curved, extremely 

 slender and acute towards the tip. There is a strong sub- 

 basal tooth, directed sligntly upwards. 



Maxillce very thick, short, bristly, the joints decreasing rap- 

 idly in diameter. Without dissection I do not feel able to 

 pronounce upon details. 



Mentum apparently quadrate with the anterior angles pro- 

 duced. The palpi are short, bristly, and very thick. 



Prothorax longer than wide narrowed and rounded in front, 

 with a slight apical emargination, hind angles rounded. Sur- 

 face minutely rugose, a patch of large deep punctures being 

 arranged in irregular lines on each side of the middle. Near 

 the base is a vague transverse impression, more evident at
