LYCUS. 3 
4. Lycus godmani. (Tab. I. fig. 2, ¢.) 
Niger, thorace ochraceo; elytris rubricatis, basi ochraceis, his sutura usque ad medium, illo vitta mediana 
nigricantibus. 
Mas elytris infra humeros rotundato-ampliatis ; prothorace lateribus subparallelis, angulis posticis fere rectis, 
paulo productis. Long. 15 millim., lat. 10 millim. 
Femina elytris magis ovalibus, minus ampliatis; prothorace basi latiore, anigulia posticis acutis, lateribus 
explanato-elevatis. Long. 14-18 millim., lat. 7-10 millim. 
Hab. Mexico, Misantla (Hoge, 3 2 ), Cordova (Sallé, 2 ). 
This distinct and beautiful species forms a transition to the Lycostomi, while retaining 
in a considerable degree the inflated form of typical Lyct. The abdominal segments are 
of the normal structure; the seventh segment in the male is acutely cut out in the 
middle. In some specimens the abdomen has the sides yellow, but is usually black, 
with the head and limbs of the same colour. ‘The elytra are brick-red, shading into 
ochreous at the base; the third nervure is but little raised, the sculpture between very 
intricate ; while intermediate longitudinal nervures can be traced, there are no trans- 
verse cells, but confluent and rugose punctuation. The females have the sides of the 
prothorax more expanded and reflexed than the male (possibly owing to their being 
larger specimens) ; it is carinate in front, obsoletely channelled in the centre of the disk. 
A central vitta, the scutellum, and suture as far as the middle of the elytra are black. 
The figure is from the Misantla specimen. 
5. Lycus scutellatus. 
Niger, prothorace elytrisque rubris, his circa scutellum et ad apicem late, illo vitta mediana nigris. 
Mas elytris apicem versus dilatatis, segmento ventrali septimo apice haud exciso. Long. 15 millim. 
Femina elytris minus dilatatis. 
Hab. Mexico, Cordova (Sallé, 3 @ ). 
This appears to be a variable species. Of the three examples in M. Sallé’s collection 
the two males have almost half of the elytra black, while one wants the black scutellar 
patch; and this example is of paler yellow, and has the base of the femora, the rostrum, 
and sides of the abdomen yellow. The female has only the apical third and the 
scutellar region black. The legs are black; but the anterior two pairs at the extreme 
base and the sides of the abdomen are yellow. 
The elytra are strongly costate, with subrugose interstices, the third nervure less raised 
than the others. The black apex of the elytra sufficiently distinguishes it from L. godmani, 
to which it is clearly allied. 
6. Lycus sallzi. 
Niger, femorum basi et abdominis lateribus flavis, prothorace elytrisque ochraceis, his basi ac tertia parte 
apicali, illo vitta mediana nigris; elytris postice paulo ampliatis, interstitiis lineis transversis nonnullis 
reticulatis. Long. 18 millim., lat. 10 millim. 9°. 
Hab. Mexico, Puebla (Sallé, ¢ ).
