reacliing a trifle beyond the base of the head and fourth to the 

 middle of the fore coxae. Pronotum widened posteriorly, 

 hind margin convexly rounded. Anterior margin a little 

 emarginate, the interolateral angle acute and prominent, 

 Scutellum separated. Tegminal pads long and slender, promi- 

 nently tuberculate anterolaterally (as also the wing pads). 

 Prosterna sulcate, but not striated for stridulation, fore coxae 

 almost contiguous. Meso-and metasterna not sulcate, appar- 

 ently not divided, middle and hind coxae remote, the left from 

 the right, the hind coxae articulated remote from the hind 

 margin of the metasternum. Each of the tergites (except the 

 apical) has a slender lateral spine which is an elongate tubercle 

 on the first ones, but the last three are elongate, laterally 

 porrect except the apical one (on the penultimate segment) 

 which is oblique. According to Swezey, the whole nymphal 

 period occupies 29 to 34 days. 



Fam. Anthocoridae. 



These bugs are probably mostly insectivorous, being fierce 

 foes of Aphids, Chermids, Psocids, Bark-beetles, young leaf- 

 hoppers, etc., though they perhaps also feed on minute fungi. 



The only notes on their metamorphoses are those of Swezey 

 (*^), who has partially studied them. 

 15 Triphleps presequens and 16 Physopleurella mundulus. 



The eggs are elongate oval with a raised collar at the 

 micropyle end. They are deposited singly on leaves, etc. 



Fam. Miridae. 



The known ova are inserted, much as in Asiracids, in the 

 leaves or stems of plants. The metamorphoses of Poecilocapsus 

 lineatus (*^) and Eelopeltis theivora C^), etc., have been 

 studied. 



This family is mostly phytophagous, but some species are 

 insectivorous, caterpillars, butterfly's eggs, aphidae, etc., form- 

 ing their prey. Miris dolahratus has been reported as attacking 

 a Dipterous adult, but it is scarcely credible, the bug having 

 probably been really a Reduviolns. Plagiognathus ohscurus 

 is recorded as biting a human being.
