2. Phanomcris fragilis, Hal. 

 Colastesfragilis, Hal., Ent. Mag., iv., 56, ? . 



$ . Black ; palpi and legs dull testaceous ; wings infiimated ; 

 terebra very short. <y . Hind coxae, femora above in the middle, 

 tibiae at the tips, and tarsi, infuscated ; segment 2 striolated at the 

 base. <y 5 . Length, 1^ ; wings, 2| lin. 



? . " Head a little narrower than the thorax, subglobose, very 

 smooth ; antenna3 about as long as the body, slender, 24-jointed ; 

 thorax elongate, attenuated before and behind ; prothorax narrow ; 

 mesothorax very smooth, the sutures rudimentary ; metathorax 

 somewhat scabrous ; abdomen oblong, lanceolate, 1st segment 

 very short, somewhat scabrous, or roughened with punctures, not 

 carinated ; the remaining segments very smooth, fusco-piceous ; 

 terebra very briefly exserted ; legs ochreous ; wings narrow, in- 

 fumated, stigma and ner^^.lres fuscous, the former elliptical, lanceo- 

 late, receiving the radius in the middle ; prae- and pobrachial 

 nervures approximated in the middle ; pobrachial areolet of the 

 hind wing shorter than ^ the prsebrachial."— Haliday. 



The <y has 31-jointed antennae ; mesothoracic sutures almost 

 obsolete; metathorax with a few minute wrinkles, very shining; 

 abdomen black. Sides of segment 1, and suturiform articulation 

 pale ; wings slightly infumated, as in no other allied species. 

 Occiput not visibly margined. Suturiform articulation distinct, 

 not crenate. Legs sometimes marked with fuscous. Otherwise 

 like the ? . 



The Foi'sterian genera being often so constructed as 

 to admit but one species, it is dijfficult to refer to its 

 place any form with which he was not acquainted. The 

 present insect seems best to agree with I'lmnomcris, on 

 account of the distinct suturiform articulation. 



The ? was taken near London by Walker. A <? by 

 Fitch in the New Forest, and two more by Bignell in 

 Devonshire.

 Forst., Verb. pr. Eheinl., 1862, p. 235. 



Suturiform articulation obsolete. Head protuberant at the l)ase 

 of the antennae. Mesothoracic sutures distinct, punctulate. Eadius 

 originating beyond the middle of the stigma.
