Heud abruptly naiiuwed and prolonged anteriorly, not (juite as 

 broad as the thorax, obliquely narrowed behind the rather small but 

 prominent eyes; frontal channel deep, only moderately broad, and end- 

 inc^ iust in front of the eyes; interocular foveae small and distinctly 

 separated from the eves. Thorax of ahnost equal length and breadth, 

 very 4io-htly wider at the middle than elsewhere, a good deal narrowed 

 anterioidv; the groove near the base extends to the lateral impressions 

 and at tlie middle, forms a very small angular fovea. Elytra a third 

 k.nger than tlie thorax, broader than they are long, considerably 

 narrowed towards the base, which is just perceptibly wider than that 

 of the thorax; sutural striae well marked, deep and foveiform at the 

 base, the dorsal impressions short l)ut still deeper and broader, and 

 only' indefinitely prolonged backwards. Hind-body nearly as long as 

 the elytra, narrowed and gradually deflexod posteriorly, its basal three 

 segments equal, finely and distantly punctate. 



Legs elongate, femora moderately clavate ; anterior tibiae gently 

 curved below the middle, the intermediate rather stouter, neither bent 

 nor densely pubescent near the extremity, slightly arched externally, 

 the posterior similarly curved, with a conspicuous spine on the inside 



below the middle. ci-aa 



On comparison with the male of tlie nortliern //. .sf emails, 2^44 

 (Ann. Mag. Nat. Hist., ser. 6, vol. 12, p. 168), it will be at once noticed 

 that the head and thorax of this species are evidently narrower; the 

 interocular foveae are only about half as large, and, instead of touch- 

 ing the eyes, they are distant from them; these organs are smaller; 

 the 5th and 6th joints of the antennae are slightly longer, the terminal 

 is subconical and truncate at its base, wliereas the corresponding joint 

 in 2744 is oblong-oval and narrowed towards the base; the tibiae also 

 differ, the intermediate pair of 2744 being slightly bent and obviously 

 pubescent near tlie extremity, and the insect itself is more robust. The 

 structure of the underside is nearly similar in lioth, but in this species 

 the inetasternum is more deeply concave longitudinally and the apical 

 segment is large and subrotundate. 



Ji'em. — Body stouter, with tliicker antennae; the head and thorax 

 more slender tlian in the same sex of 2744.

Oblong, transversely convex, without tubercular elevations, varie- 

 gate; head and thorax' opacpie, fusco-piceous, the explanate sides of the 

 latter reddish, elytra pitchy-red, tlie bare spots shining; tarsi and 

 antennae fusco-rufous, the legs variegated with coarse pale and fuscous 

 setae. 



Head flat between the elevated antennal tubercles, gi-anulate, and 

 bearing numerous erect, squamiform, flavescent setae. Thorax a third 

 broader than long, granulate, with a small median basal depression; 

 its fulvescent setae finer than those on the head and somewhat concen- 

 trated in patches, the most conspicuous being a pair of elongate frontal 

 ones; the sides are fringed with coarse outstanding setae; the anterior 

 lobe is large, and projects as far as the front of the eye; there is a
