quite two times as wide as long, widest at base, distinctly narrower 

 in front than behind; sides strongly, obliquely attenuate from baso 

 to apical angles; posterior angles acute and projecting; anterior 

 margin nearly truncate at sides, with a broadly rounded median lobe ; 

 surface coarsely and rather densely punctate, the punctures deep and 

 irregularly placed. Scutellum oval, somewhat truncate in front. 

 Elytra a little wider than pronotum at base, slightly dilated behind 

 the humeri, feebly sinuate at posterior coxae, then arcuately attenu- 

 ate to the tips, which are truncate and rather strongly dentate ; sur- 

 face striato-punctate, the punctures fine, shallow, and distinctly sepa- 

 rated; intervals nearly flat, with a few coarse, irregularly placed 

 punctures. Abdomen beneath coarsely and rather densely punctate^ 

 the punctures variable in size and irregularly placed ; intervals finely, 

 densely granulose and sparsely clothed with fine semi-erect hairs; 

 first segment broadly and deeply longitudinally grooved at middle; 

 last segment broadly truncate at apex, with a small tooth on each 

 side, the yellow spot at each anterior angle sometimes quite large 

 and forming a fascia, but usually small and rarely missing. Pros- 

 ternum flat, sparsely and coarsely punctate, and the anterior margin 

 nearly truncate; prosternal process narrow, not or only obsoletely 

 sulcate at middle, parallel to behind the anterior coxal cavities, then 

 obliquely attenuate to the apex, which is acutely rounded. Anterior 

 femora strongly swollen at middle; anterior tibiae emarginate, flat- 

 tened on the inner side and armed with a large broad hook ; anterior 

 tarsi much broader than the posterior ones. 



Female. — Similar to the male, but the head is a little more convex, 

 yellow markings not as much extended, last ventral segment more 

 rounded at apex, and the yellow markings more prominent, the an- 

 terior tarsi more slender and the anterior tibiae not armed with a 

 hook at the apex. 



Length, 10-14.5 mm. ; Avidth. 4.5-6 mm. 



The name maculipennis was first used in this genus by Dejean 

 (1833), without giving any description, but Gory (1840) described 

 the species from a specimen in the Dejean collection from North 

 America. This species is distributed over the eastein United States 

 from Maine to Louisiana and westward to Missouri. It is closely 

 related to lineata, but can be readily distinguished from that species 

 by the yellowish elytral markings, more oval in form, and dis- 

 tinctly brassy tinge. The larvae is recorded as living in pine and 

 hemlock. 



It has been recorded by Fleutiaux and Salle (1890) from Guade- 

 loupe, but no specimens of this species have been examined from the 

 West Indies.
