292 PHYTOPHAGA. 



Eab. Mexico 1 2 , Guanajuato (coll. Salle), Oaxaca (Edge, SalU) ; Guatemala (coil. 

 Salle). 



Only two specimens from the last-named locality are contained in the Salle collection ; 

 Mr. Champion did not met with this insect. 



2. Phrynocepha deyrollei. 



Phrynocepha deyrollei, Baly, Trans. Ent. Soc. 1876, iii. p. 444 \ 



Eab. Mexico 1 , Guanajuato, Yolotepec, Capulalpam, La Parada, Oaxaca, Puebla 

 (coll. Salle) ; Guatemala (coll. Jacoby). 



The smaller size (less than half), black underside, and more finely punctured elytra 

 distinguish this species from P. pulchella. The typical description was drawn from a 

 single male specimen contained in the collection of Mr. Baly. The female insect, of 

 which many specimens, together with the other sex, are contained in the collection of 

 M. Salle, shows the same proportionate differences as in the case of P. pulchella, and 

 some of these specimens have the elytra obsoletely costate throughout ; others again 

 are more bluish in colour and not so opaque as in the type, but there are scarcely any 

 other differences to be found to justify their separation. 



3. Phrynocepha elongata. (Tab. XVIII. figg. l, 2.) 



c?. Elongate, blackish blue below; four first joints of antennae, head, thorax, and legs fulvous; elytra dark 

 blue, opaque, impunctate ; tarsi dilated. 



5 . Larger and broader, tarsi more elongate ; antennae more robust. 



Length 3-3| lines. 



Head deeply rugose-punctate, with a triangular, medially depressed ridge at the vertex ; frontal tubercles 

 strongly raised, elongate ; antennae half the length of the body, not thickened at the base, the third and 

 fourth joints of equal length ; four lower joints, and the base of the fifth, fulvous, the rest black ; thorax 

 narrowed in front, the sides much rounded at the middle, surface very finely and rather closely punctured, 

 middle of the disk obsoletely longitudinally raised, the sides and the base with some very obsolete depres- 

 sions ; scutellum black ; elytra parallel, elongate, opaque, entirely impunctate, of a dark bluish colour ; 

 tarsi very broadly dilated. 



Eab. Mexico, Cordova (SalU), Oaxaca (Edge). 



Although in its general appearance this species does not much resemble the preceding 

 two, I have no doubt about its proper place in this genus ; it differs, however, in the 

 shape of the antennae, which are not widened at the base, but of equal thickness, and 

 in the less dilated tibiae ; in other respects, the elongate head, small eyes, and shape of 

 the thorax are identical with those of its allies. P. elongata may at once be separated 

 by the equal third and fourth joints of the antennae, their colour, and by the elongate 

 shape of the insect. In the female the joints of the antennae are much more robust 

 and shortened, and the tarsi more elongate, but there is no other difference of any 

 importance to be seen. The basal thoracic groove in this insect is almost absent, or 

 only very indistinctly indicated, in which it differs therefore from P. pulchella.
