Haliplus concolor Leconte. 



Haliplus concolor Leconte. Ann. Lye. Nat. Hist., V, 1852, p. 201. 



Species entirely rufous. Length 2.5 mm. 



Head sparsely punctate, the punctures very small ; labruni truncate, the 

 anterior margin with a row of fine sets. 



Pronotum with a pair of small, basal, dark areas, punctate, the disc 

 sparsely so, punctures of the sides and front smaller than those of the base. 

 Prosternal ridge margined, deeply grooved in front, punctate. Posterior 

 coxae rounded behind, punctate, reaching the fourth segment of the abdomen ; 

 abdominal segments shining, smooth, a few scattered punctures being present. 



Each elytron with ten rows of punctures of the same color as the elytra ; 

 punctures not so deeply impressed towards the tip ; intervals with few small 

 punctures ; apices of elytra rounded, not sinuate. 



Re-described from one specimen collected at Brownsville, Texas. 

 In the collection of Prof. H. F. Wickham, Iowa City, Iowa. 



Habitat. — Colorado River (Leconte) ; Texas (Brownsville, H. F. 

 Wickham). 



Type. — In the Museum of Comparative Zoology, Cambridge, Mass. 

 Described originally by Leconte from one specimen from the Col- 

 orado River. 



Haliplus connexus, new species. 



Color pale yellow, rarely rufous, with black spots and margins on elytra. 

 Length 4 mm. 



Head punctate except a small area on vertex ; eyes nearly circular in 

 outline ; labrum emarginate, rounded at the sides, a row of fine setse on 

 anterior margin ; antennae testaceous. 



Thorax entirely pale yellow, rarely rufous ; pronotum punctate except a 

 linear transverse area on disc, the punctuation stronger at base than at sides 

 and front ; punctures of same color as thorax ; paired basal impressions want- 

 ing ; prosternal ridge margined, convex transversely and longitudinally, not 

 grooved, sharply declivous in front, sides slightly constricted in region of 

 prothoracic legs, widening again anteriorly. Abdominal segments smooth and 

 shining, the last one triangular in outline and punctate at apex and sides, the 

 base impunctate; the remaining segments except the third, each with a row of 

 punctu'res on posterior margin. Legs pale yellow, posterior coxae punctate, 

 rounded posteriorly, extending to the fourth segment of abdomen. 



Elytra with black spots and margins more or less connected by fine lines 

 as shown in Plate XV, the spots and margins not so large and more con- 

 nected than in H. fasciatus Aube. The sutural stripe never reaches the first 

 row of large punctures in front of the median black spot as it always does in 

 fasciatus and this makes one of the most available characters for separating 

 these closely allied species. Each elytron has ten rows of shallow punctures
