separated from the metasternum by a straight crenulate stria ; 

 the metasternum and first abdominal segment are rather more 

 clearly punctate than the mesosternum ; the legs slender, with 

 the anterior tibiae conspicuously swollen before the middle. 



The widening out of the prosternal striae is a generic 

 character in SdctoU'x.

Stictotix frontalis. 

 Limnichus frontalis, Macl. Trans. Eut. Soc. N. S, W. ii. p. 172 (1871). 



Late ovalis, convexiusculus, rufo-brunneus, nitidus ; fronte conspicue 

 bicarinata; elytris 12-striatas ; metasteruo punctato, punctis in 

 medio luniformibus. 



L. 2 miU. 



Broadly oval, somewhat convex, reddish brown ; the head, 

 surface granulate, vertex concave, concavity bordered on either 

 side with a well-marked oblique carina ; the thorax nearly as 

 wide again at the base as in front, lateral margin narrowly 

 elevated, granulate within the anterior angles and behind 

 the neck, marginal stria behind the head obscurely crenulate ; 

 surface punctuation very distinct, somewhat large, shallow, 

 and not quite circular, the interstices between the punctures 

 are abcut the width of the punctures themselves; the elytra, 

 there are twelve striae on each elytron, that which is appa- 

 rently the outer humeral is punctiform, the sutural is joined 

 at the base to the third from the suture, the two intervening 

 striae represent probably one stria formed as two. In S. Mar- 

 moni, Lew., where the sutural is joined to another in a similar 

 manner, there is only one intervening stria. The interstitial 

 punctuation, so peculiar in this genus, is arranged in rows ; 

 the propygidium and pygidium are coarsely, rather densely, and 

 evenly punctured; the prosternum, the lateral strise are tine, 

 carinate, and oblique before the coxte, the anterior lobe has 

 a rather broad granulate border along the anterior edge 

 and a very few and ye,xy much scattered punctures, some 

 incompletely circular ; the mesosternum has punctures set 

 transversely, several are crescent-shaped, the transverse stria 

 is widely crenulate ; the metasternum is curiously punctured, 

 the punctures in the median area are crescent-shaped, on the 

 outer area circular, neither are closely placed ; the legs are 

 slender, tibige not dilated; the antennee, basal joint nearly as 

 long as all the others together. 



The outline of this species is broader than any other of 

 the described species of this genus.
