HYMENOPTERA 



The order Hymenoptera is one of enormous extent, including the ants, bees and wasps, saw- 

 flies, gall-flies, ruby-wasps, ichneumons, etc. They possess two pairs of membranous wings which 

 are destitute of scales and more or less transparent ; the anterior wings are larger than the posterior. 

 In some species, however, one or both of the sexes may be apterous. The females are in some 

 families provided with a sting, in others with a sawing, boring, or piercing apparatus. In the 

 sawflies the abdomen is broad at the base where it joins the thorax, and there is no sharp distinction 

 between the two regions, the lateral outline of the body being therefore continuous ; but in the 

 other groups the base of the abdomen is suddenly contracted into a slender ' waist ' or petiole of 

 varying length in different species. These differences are utilized as a means of dividing the order 

 into two sub-orders : the Sessiliventres, in which the thorax passes almost imperceptibly into the 

 abdomen, and the Petiolata, in which there is a deep constriction between them, and the transition 

 is therefore abrupt and sharply defined. 1 This difference in structure is accompanied by striking 



1 The expressions ' thorax ' and ' abdomen ' are here used in a somewhat loose sense. In the Petiolate 

 Hymenoptera the first segment of the abdomen is completely fused with the thorax, and the ' waist ' or stalk 

 is formed by the second (and sometimes the third) abdominal segment. The petiole or constriction is there- 

 fore, strictly speaking, not between the thorax and abdomen, but behind the first segment of the latter. It is 

 usual to speak of the thorax, plus the first abdominal segment, as the alitrunk, and to restrict the term abdomen 

 to the part behind which commences with the true second segment.
