90 PHYTOPHAGA.—SUPPLEMENT. 
Saxinis saginata (p. 36). 
To the locality Mexico, add :—Cuernavaca (Sallé), Oaxaca (Hége), Chilpancingo in 
Guerrero (H. H. Smith). 
This is the largest species of the genus and it has the lateral lobe of the elytra 
distinctly angulate; the elytra themselves are very deeply but not very regularly 
punctate-striate. According to Dr. Horn, 8. sawcia, Leconte, is synonymous with the 
present insect. | 
8 (a). Saxinis hogei. (Tab. XXXVII. fig. 11.) 
Metallic greenish-blue ; antenne black; head closely punctured; thorax closely and strongly punctured at 
the sides; elytra very strongly punctate-striate, the interstices impunctate and rather convex, a sub- 
quadrate spot on the shoulders rufous. . 
Length 13-2 lines. 
Of somewhat posteriorly narrowed shape, the. head closely and strongly rugose-punctate, the vertex strigose, 
the labrum and palpi black; antenn not quite extending to the base of the thorax, black, the second 
and third joints obscure fulvous ; thorax twice as broad as long, the sides but slightly rounded, the disc 
remotely, the sides closely and strongly, punctured ; scutellum deeply punctured ; elytra flattened, but not 
visibly depressed below the base, very deeply and closely punctate-striate, the interstices smooth and 
shining, subcostate, the lateral lobe rather rounded and moderately produced, the shoulders with the usual 
subquadrate fulvous or rufous spot. 
Hab. Mexico, Ventanas in Durango, Tupataro in Guanajuato (Hoge), Amula and 
Xucumanatlan in Guerrero (Smith). 
In its metallic-blue colour S. hégei most nearly resembles S. sonorensis, though 
differing from that insect and most of its allies in the impunctate and rather convex: 
interstices of the elytra. SS. saginata is a very closely allied species, but is larger and 
more robust. The numerous examples obtained all agree in the above particulars, and 
although they may possibly represent only a small variety of S. saginata, I must 
consider them at present as distinct, no intermediate specimens having come under my 
notice. 
6. Saxinis hirtipennis. 
Dark greenish-blue ; head strigose-punctate; thorax shining, closely punctured at the sides; elytra more 
opaque, closely punctate-striate and clothed with short pubescence, each with a subquadrate fulvous 
humeral spot; below densely pubescent. 
Length 23 lines. 
Of broad and flattened shape, metallic greenish-blue, the head very closely longitudinally strigose and finely 
punctured, the eyes reniform; antenne extending to the base of the thorax, black, the basal joint obscure 
metallic blue, the third joint slender and more elongate, the following joints strongly transverse; thorax 
twice as broad as long, the sides evenly and strongly rounded, the anterior angles produced into a blunt 
point, the surface transversely convex, very deeply and closely punctured at the sides, more remotely and 
finely so on the disc; scutellum strongly and closely punctured ; elytra slightly depressed below the 
scutellum, flattened on the disc, distinctly and regularly, but not very strongly, punctate-striate, the 
interstices finely transversely rugose, sparingly punctured, and clothed with a very short whitish pubes- 
cence, the shoulders occupied by a subquadrate fulvous spot extending inwards to the sixth row of
