TEMNOCHILA, 407 
. Hab.: Muxico, Parada (Sallé), Las Vigas (Hoge).. 
Although very closely allied to 7. sulcifrons, the distinctions that will be gathered 
from the above diagnosis seem -to me indicative of another species, of which, however, 
we have received only three examples; one of them—the only male—is an aberration 
in which the pigmentary matter is deficient, leaving the ground-colour reddish instead 
of black. This sort of deficiency occurs in other species of the genus. : 
24. Temnochila smithi, sp. n. (Tab. XIII. fig. 9.) 
Subdepressa, nigro-viridis, supra viridi-aurata, antennis nigris; capite posterius fortiter, sat crebre, anterius 
subtilius punctato ; prothorace medio longitudinaliter late depresso, basin versus fortiter angustato, margine 
laterali crasso, in medio sinuato-depresso et denticulato, sat crebre minus fortiter punctato; elytris sat 
nitidis, subleevigatis; abdomine parce minus fortiter punctato ; area submentali levigata. 
Long. 14-20 millim. 
‘Mas, area submentali medio fasciculo sat magno armata; abdomine segmentis 1°-4™ ad latera punctis adjectis 
parum numerosis. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith), Mochitlan in Guerrero 
(Baron), Yolotepec (Sallé). 
__ This species is closely allied to 7. sulcifrons and T. derasa; but is distinguished by 
the deeper and broader depression along the thorax, the almost polished elytra, and 
the golden tint of the upper surface, and by the prosternum being more prominent 
behind the coxe. Although this latter character brings it somewhat near to the 
species of the next group (Z. polita &c.), yet the shape of the thorax with its thick 
lateral margins is quite the same as we find characteristic of 7. planipennis and its 
allies ; the channel on the head is very deeply impressed, as in 7. swlcifrons. 
Mr. H. H. Smith secured a series of about twenty examples of this elegant insect in 
July and August 1888; the single example from Yolotepecis a variety with the surface 
comparatively dull. 
25. Temnochila diffinis, sp. n. 
Nigro-viridis, supra enea, antennis nigricantibus ; capite prothoraceque crebrius fere subtiliter punctatis, illo 
anterius minus profunde canaliculato; elytris seriatim subtilius remote punctatis ; prosterno pone coxas 
prominulo sed haud conico-elevato. 
Long. 13 millim. 
Mas incog. 
Fem., segmentis ventralibus sat crebre et fortiter punctatis, segmento ultimo inimpresso. 
Hab. Mexico, Jalapa (Hoge, M. Trujillo), Bobo (Hoge); GUATEMALA, Panajachel 
5000 feet (Champion). 
Head moderately broad, moderately closely and finely punctate. Thorax somewhat 
rounded at the sides in front, with a rather deep impression close to the side-margin 
behind the middle; behind this a good deal narrowed towards the base ; lateral margin 
not very coarse, the front angles but little produced ; the punctuation fine. Elytra quite 
finely and remotely punctate. Prosternum moderately finely, sparingly punctate.
