suture nearly to the middle, the intervals between that and the apical 

 sutural dark area being very narrowly piceous. Body beneath with 

 the breast piceous and abdomen dark brown, femora dark above and 

 at apex, tibiae and tarsi dark. Length 6.8 mm.; width 3.5 mm. 



Type, female, CAS, from the valley of the Rio Monzon, Tingo, 

 Maria, Peru, collected by E. I. Schlinger and E. S. Ross, Dec. 2, 1954.

 to H. peruensis with slightly different markings.

Figure 86 



Between 5.5 and 7.5 mm. in length, oblong oval, somewhat shiny 

 although alutaceous, the elytra strongly costate with the intervals 

 geminate striate punctate; pale yellow brown, the head on top and 

 sometimes below shining piceous, the elytra with a piceous lateral 

 vitta extending part way down the side to below the middle, a short 

 sutural vitta not reaching the middle, a large spot at the apical curve 

 on each elytron and a short apical sutural vitta; breast piceous, legs pale. 



Head with the interocular space about half its width, occiput 

 polished, finely punctate, frontal tubercles somewhat swollen with a 

 median depression above, lower front depressed; piceous, sometimes 

 the lower front pale or in part pale. Antennae deep brown to piceous 

 with the terminal three joints pale, tip of last joint dark. Pro thorax 

 a Uttle wider than long, with slightly curved sides and a transverse de- 

 pression, alutaceous and in places densely and finely punctate; pale 

 yellow brown. Scutellum tending to be pale, sometimes dark brown. 

 Each elytron with 7 or 8 costae, the intervals being geminate striate 

 punctate, pale yellow brown with a wide piceous lateral vitta extend- 

 ing not quite to middle, and another shorter sutural one near the apex, 

 and a large spot at apical curve. Body beneath pale with the breast 

 shining piceous, legs pale. Length 5.7-7.5 mm.; width 3.2-3.7 mm. 



Type, female, MCZ 30680; two paratypes, one USNM, one MCZ; 

 all from Salinas, Beni River, collected by M. Stuart, July 1895. 

 There are also five specimens, all females, from Cochabamba, Bolivia, 

 collected by Germain; specimens from Siamas and Rurrenabaque, 

 Rio Beni, Bohvia collected by W. M. Mann, October 1922, from 

 Loma Alta, Bolivia, collected by Pinckert, May 21, 1957; Misiones 

 Province, Argentina, Monros' collection, USNM. 



Remarks : Bowditch has attached the manuscript name heniensis to 

 this species. It is closely related to H. marginalis (Fabricius) and 

 others with the front of the face depressed and the elytra strongly 

 costate.
