492 CLASS INSECTA. 



pery, with hairs of a yellowish grey underneath. Found on 

 umbelliferous flowers. 



T. fasciatus, S. fasciatus, Lin. Oliv. ihid. ix. 84, a little 

 smaller, black, with thick yellow hairs ; cases of this last 

 colour, with three black bands, transverse, and interrupted 

 at the suture. Very common in spring, upon flowers. 



T. Eremita, S. Eremita, Lin. Oliv. ihid. iii. 17- Large, 

 of a brown black ; edges of the head raised ; three furrows 

 upon the eorslet. Found on the trunk of old treeS;, in the 

 interior of which dwells the larva. 



T. hemipterus (female), *S'. hemipterus, Lin. Oliv. ibid^ 

 IX. 83, xl. 103, and. those of some other species of North 

 America, are remarkable for the corneous auger, in the form 

 of a dart, at the posterior extremity of the abdomen, which 

 serves to introduce their eggs. 



These species commonly remain upon the ground, where 

 they walk very slowly. The last articulation of their maxil- 

 lary palpi is proportionally shorter and thicker than that of 

 other trichii. It has appeared to me that the first of the 

 posterior tarsi considerably exceeded the following in length, 

 while in the other trichii it is very little longer. 



The second division {Goliathidce) is distinguished from the 

 preceding in the character of the chin, which is much more 

 large, broad, and covers the jaws. 



In some the chin is concave in its middle, having the figure 

 of a widened heart, or of a transverse square. The interior 

 extremity of the hood is neither denticulated nor corneous. 

 The corslet is in the form of a heart, truncated at the two 

 ends, and narrowed abruptly behind, or in the form of a 

 transverse square, rounded laterally. 



The first articulation of the antennae is very large, trian- 

 gular, or in an inverted cone. The palpi are short ; the last 

 articulation of the maxillary palpi is elongated. The external 

 side of the first two legs presents two teeth.
