THE VELVET WATER-BUGS. 



609 



with fuscous; under surface piceous, shining, thickly covered with a 

 minute grayish pubescence. Antennae shorter than in any of our other 

 species, joint 1 dull yellow, 2 — 5 dark brown, 1, 3 and 5 subequal in 

 length, 2 and 4 much shorter. Pronotum narrower with sides more 

 constricted at middle than in consolidus ; disk with a more distinct median 

 groove and punctures scarcely evident. Beak reaching first ventral. 

 Length, 1.8—2.1 mm. (Fig. 151, a). 



Miami, R. P. Park, Bassenger, Sarasota, Ft. Myers and Dun- 

 edin, Fla., Nov. 23 — April 16. Occurs beneath boards and 

 other cover about the margins of ponds and ditches, often in 

 company with consolidus. Common at Ft. Myers in the muck 

 of an extinct wet weather pond. It is a darker, narrower, more 

 parallel-sided species than any of our others, with white mark- 

 ings of clavus and corium and short second antennal distinctive. 

 Originally described from Chapultepec, Mexico, and not before 

 recorded from this country. Champion's figure does not agree 

 with his description, as it shows but three pale spots on mem- 

 brane. The relative lengths of antennal joints in the figure 

 also differ somewhat from his description 

 and from those of the Florida specimens. 

 His unique type is in the Vienna Museum. 

 All of the numerous specimens at hand of 

 both this species and consolidus are macrop^ 

 terous.

 Severin, 1896, 51. 



Oblong, elytra subparallel. Head, except 

 tylus, pronotum, scutellum and apex of corium 

 Fig. 152. Female, x 17. dark f uscous-brown ; tylus and coriaceous part 

 of basal two-thirds of corium dull brownish-yel- 

 low; bucculae, beak, first antennal and legs straw-yellow; knees, tibia? 

 and tarsi tinged with fuscous; pale markings of clavus and corium much 

 as in concinnus, the submarginal line on corium less distinct; markings 

 of membrane as in consolidus. Antennae distinctly shorter and stouter 

 than in concinnus, joints 2 — 5 dusky-brown, their relative length as in 

 key. Pronotum broader across humeri than in either consolidus or 

 bilineatus, the sides therefore appearing more constricted in front of 

 humeri than in those species, disk with a well defined median groove, 

 coarsely, sparsely, unevenly punctate. Coriaceous part of corium clothed 

 with conspicuous prostrate yellow hairs. Both macropterous and bra- 

 chypterous forms are known. Length, 1.8 — 2.1 mm. (Fig. 152).
