Tribe VI. SCYMXIXI. 



This tribe embraces a large number of small species readily 

 recognized by the distinct pubescence of the upper surface. The 

 genus Sniilia, though composed of apparently glabrous forms, is 

 combined with the other genera, on account of a similarity in struc- 

 ture. In all our forms the antenme are scarcely as long as the 

 head, thorax deeply emarginate in front and rounded behind; front 







and middle legs more or less contractile, with the thighs sulcate be- 

 neath for the reception of the tibhe. Casey separates the tribe into 

 six genera, four of which are represented in Indiana.

ti. Thorax not deeply emarginate ; antenme apparently 11-jointed, free; 



front coxae moderately separated. 



1>. Thorax with a fine, obliquely impressed line behind the front angles; 



liiidy apparently glabrous, yet finely pubescent under high power; 



tarsal claws simple. XV. SMILIA. 



lib. Thorax without an oblique line near the front angles; body always 



distinctly pubescent : tarsal claws bifid. 



c. Clypens prolonged for a considerable distance before the eyes, the 

 sides converging; antenrue inserted in small shallow emargina- 

 tions just before the eyes: prosternum flat, not at all detlexed 

 toward the tip. generally bicarinate. XVI. SCYMNTS. 



cc. (Mypeus extremely short before the eyes, truncate with rounded 

 angles, the antenna- inserted under its sides adjoining the eyes; 

 prostermnn transversely convex, not carinate, broadly and grad- 

 ually detlexed, forming a protection to the mouth in repose. 



XVII. STETIIORUS. 



(/. Thorax very short and broad and deeply emarginate in front; antenna? 

 apparently 0-jointed : front cox;e very widely separated.

Here belong very small rounded species formerly classed under 

 tin 1 genus PC it I Uiit. Of the six listed from the United States, one is 

 known from Indiana.

Oval, convex. Filiform black, shining. Thorax nearly smooth, the 

 impressed line near the front angles line and indistinct. Elytra rather 

 coarsely, sparsely and somewhat unevenly punctate. Length .S-l mm. ( Fig. 

 193.) 



Throughout the State; frequent. April Ki-May 20. Occurs 

 especially on fruit trees inl'esled \vifh San -Jose scale and one of the 

 most beneficial beetles pi-eying upon that injurious insect.
