 'I'liis family very closely resembles the family Plcronudiihr, and the two are sep- 

 arated with difficulty, the only reliable character to separate them being the num- 

 ber of apical spurs on the hind tibise. In this family the hind tibire have lira apical 

 spurs, while in the Plrronutlidn' there is but one apical spur. It is a good character 

 l)ut not easily seen in the smaller species, and the greatest care and caution must 

 be exercised in examining specimens before they can be placed in their proper fam- 

 ilies. A very strong lens is required to see the spurs and sometimes it will be found
