22 Mr. J. O. VVestwood's Observations 



(a minute apparent joint at the base of the third joint not being 

 computed) (fig. Sc). The neuration of the hemelytra (fig. 3 e), 

 and the male (fig. 3 h) and female abdomen (fig, 3 d), are almost 

 identical with those of Vhymala crassipes. 



Thus it will be seen that Latreille characterized his first section 

 from a male specimen of Fhymata crassipes, and his second section 

 from a female of Phymata erosa. 



The following is a description of a new and remarkable species 

 in this genus which difters in several respects from its generic 

 characters. 



Phymata Integra (n. s.) (PI. 2, fig. 1.) 

 Pallide albido-lutea, thorace elongato, antice attenuato, lateribus 



subrectis, capite baud bifido. 

 Long. corp. lin. 5^. 



Habitat ? In Mus. Britannic, 



Totum corpus pallide albido-luteum, abdominis marginibus 

 fusco-maculatis ; hemelytrorum corium concolor, membrana 

 apicalis subhyalina, nubila fusca versus basin, venis pallidis. 

 Pedes antici concolores, femora postica fascia centrali apice- 

 que fuscis, tibiis tarsisque fuscis, illis fascia media lutea. Ab- 

 domen lateribus rotundatis, nee angulatis. Thorax elongatus, 

 antice attenuatus, in medio transverse sulcatus, portione pos- 

 tica carinis duabus divergentibus, lateribus fere rectis ; an- 

 gulis posticis lateralibus margineque postico utrinque versus 

 basin scutelli tuberculatis. Caput crassissimum, antice baud 

 bifidum; antennae mutilata}, articulo Inio brevissimo, Sdo 

 brevi. 

 Obs. — E Phymatis reliquis differt thorace elongato lateribus 

 fere recto, abdomine rotundato capiteque integro. (PI. 2, fig. I a.) 



The genus Mackocepiialus is distinguished by having the an- 

 tennae short and thick (fig. 4 a), alike in both sexes, inserted at 

 the front of the head, generally porrected and not reposing in a 

 lateral groove of the thorax, the head being in fact too long and 

 cylindrical to admit of it ; the scutellum is very large, covering 

 the entire hemelytra and wings, and extending to the extremity 

 of the body as in tlie genus Sculellcra, &c., leaving however the 

 sides of the abdomen exposed : the hemelytra being thus pro- 

 tected have the leathery part greatly reduced in size, and the mem- 

 branous part enlarged ; the veins are also very few in number 

 (fig. 4 c). The rostrum is about as long as the head (fig. 4 a, li). 

 The fore leg is represented in fig. 4 d, the hind tarsi in 4 e, the 

 extremity of the male abdomen in A-f, and of the female in 4 g.
