JALYSUS.—PARAJALYSUS, 163 
and the scutellum is armed with a small and suberect spine. ‘Three Neotropical and 
one Nearctic species have been enumerated, a fifth is here described from Central 
America. 
1. Jalysus mollitus, n.sp. (Tab. XVI. fig. 4.) 
Head ochraceous; eyes fuscous. Antenng ochraceous, obscurely speckled with fuscous; first joint much the 
longest, second a little shorter than third; fourth short, incrassated, fuscous, with the base and apex 
ochraceous ; base of the second and base and apex of the third joint also much paler in colour. Pronotum 
coarsely granulate; anterior lobe ochraceous; posterior lobe fuscous, with a pale central longitudinal line. 
Corium and membrane ochraceous. Legs ochraceous, distinctly speckled with fuscous; femora with the 
incrassated apices paler at the extremities; apices of tibie# and tarsi fuscous. Body beneath ochraceous ; 
base of abdomen somewhat testaceous; central portion of underside of head, margins of prosternum, and 
disk of mesosternum fuscous ; rostrum ochraceous, with the apex somewhat pitchy. 
Long. 73 millim. 
Hab. Guarimata, Cerro Zunil (Champion). 
This is a very variable species,—the posterior lobe of the pronotum in some specimens 
being only variegated with fuscous; in others it is concolorous with the anterior lobe ; 
the fuscous speckles on the second and third joints of the antenne are frequently con- 
fluent or subconfluent, giving those joints the appearance of being fuscous in coloration ; 
the scutellum, clavus, and membrane are also frequently suffused with fuscous. The 
granulated pronotum allies it with J. tenellus, Stél; but it is most closely allied to 
J. (Metacanthus) pectoralis, Dall. (the type and only example of which, in the British 
Museum, is from an unknown locality and mutilated as described), from which it 
appears principally to differ by the more robust thorax. 
PARAJALYSUS, n. gen. 
Allied to Jalysus, but differs in having the lateral angles of the pronotum strongly spinous. Base and anterior 
lobe of pronotum also sometimes spinous as in type described. Corium impunctate as in Jalysus, and 
apex of clavus reaching membrane as in that genus. 
1. Parajalysus spinosus, n. sp. (Tab. XVI. fig. 5.) 
Antenne fuscous, first joint about equal in length to second and third, fourth joint subequal in length to 
second, incrassated, with the apex a little paler. Head pale ochraceous, with the eyes black. Pronotum 
with the anterior lobe pale ochraceous, and armed on the disk with a long erect black spine; posterior lobe 
golden yellow, coarsely punctate or subgranulose, with the lateral margins and a central levigate line pale 
luteous, lateral angles armed with a long black spine directed upwards and outwards, and a long erect 
spine of the same colour slightly directed backwards about centre of posterior margin. Scutellum blackish, 
with a small luteous tubercle at base. Corium ochraceous, basal costal margin luteous. Membrane pale 
ochraceous and subhyaline. Legs castaneous, with the incrassated apices of the femora somewhat paler ; 
apices of the tibie and tarsi fuscous. 
Long. 5 millim, 
Hab. Mexico (Mus. Berol.); GuatemaLa, Duefias (Champion). 
This species is only known to me by a single carded specimen from Guatemala (which 
is here figured but does not allow me to describe the underside of the body), and a 
Mexican specimen (without abdomen) in the Berlin Museum.
